1) The application called "Project PAMI" aims to reduce door-to-balloon times in cardiac cath labs by improving the user interface with Kinect. It allows zooming, panning, and navigating CT scans through gestures as well as controlling C-Arm movement with voice commands.
2) This could benefit millions by reducing mortality from acute myocardial infarction. It may also reduce radiation exposure for cardiac cath lab staff and allow them to aid in diagnosis and treatment.
3) The use of gestures and voice recognition with Kinect to control medical imaging and equipment is novel and innovative. It has potential to significantly improve workflow compared to traditional remote controls.

Study: Development of a precision multimodal surgical navigation system for l...JeanmarcBasteMDPhD
Minimally invasive sublobar anatomical resection is becoming more and more popular to manage early lung lesions. Robotic-assisted thoracic surgery (RATS) is unique in comparison with other minimally invasive techniques. Indeed, RATS is able to better integrate multiple streams of information including advanced imaging techniques, in an immersive experience at the level of the robotic console.
Our aim was to describe three-dimensional (3D) imaging throughout the surgical procedure from preoperative planning to intraoperative assistance and complementary investigations such as radial endobronchial ultrasound (R-EBUS) and virtual bronchoscopy for pleural dye marking.
All cases were operated using the DaVinci SystemTM. Modelisation was provided by Visible PatientTM (Strasbourg, France). Image integration in the operative field was achieved using the Tile Pro multi display input of the DaVinci console.
Our experience was based on 114 robotic segmentectomies performed between January 2012 and October 2017. Progressively, we have reached the conclusion that the use of such an anatomic model improves the safety and reliability of procedures. The act of operating is being transformed and the surgeon now oversees a complex system that improves decision making.
It is in this dynamic and innovative setting, that my peers and I are curating an intensive training on this precision multimodal surgical system.
« Revolution in RATS » will be held in March 7th and 8th 2019.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

3. 1.) Description of Problem and Beneficiaries:
Acute Myocardial Infarction is one of the most widely cited causes of death among
millions in the world.
Statistics for the same are available at the end of this section. The statistics are far worse
for developing countries like India, Pakistan, China, and Thailand.
By using our gadget to improve the user interface of a cardiac cath-lab, we try to
reduce these mortality rates indirectly by allowing hospitals around the world to better utilize
their resources to provide better health-care to millions.
„‟We also reduce the „door-to-balloon‟ time or the time duration of the procedure that is
critical in order to significantly reduce the mortality rate due to acute MI (Myocardial
Infarction).‟‟

The above diagram is the general breakup of a cardiac cath-lab staff. The (red) marks the
optional staff required for the invasive procedure while the (blue) marks the necessary staff
required for a procedure.
Typically, the people employed at a cardiac cath lab are exposed to radiation during the
course of a procedure. Despite common preventive measures, several leading cardiologists in
India have been diagnosed with cancer. Cardiac care staff in the cardiac cath-lab are sufficiently
susceptible to radiation as well, even more so because they generally have longer shifts in
comparison to the doctors.1
Our implementation using KINECT reduces the exposure risk for all three categories of
staff in the cardiac cath lab helping devote greater resources to analysis of the CT obtained,
while maintaining the health of the cath-lab staff.
4. Common scenarios that occur when a RCIS needs to analyze a particular frame are:
(i) He requests the CVT (Cardiovascular Technologist) to zoom the „image‟ frame. The CVT
moves into the console room (wasting valuable door-to-balloon time) and zooms the image
followed by panning the zoomed image to the required part.
(ii) The technician has a delay in hearing/listening to the request of the RCIS, responds late, and
skips a few frames ahead. This results in wastage of time since the technician has to trace-back
the sequence frame-by-frame.
(iii) Due to non-central position of the technician in comparison to the „wireless sensor‟
available, the „remote‟ signal emitted does not sufficiently reach the „wireless sensor‟ making
navigation through the CT feed significantly more difficult.
a) Large scale (Benefits for the common man) : Reduce patient mortality rates by
reducing the „door-to-balloon‟ time by improving the user interface of the C-Arm and the video
control.
b) Medium Scale: Reduce radiation exposure for cardiac cath-lab staff, while improving their
utilization in diagnosis and treatment of diseases. More importantly, if the cath-lab staff isn‟t
required to control the video-feeds or the C-Arm movements in the cardiac cath-lab, then they
could possibly aid in greater amounts towards the diagnosis and treatment of the patient or in
other parts of the hospital.
c) Small scale: It would also benefit doctors by reducing their exposure time per invasive
procedure.

the RN.)‟
A list of important procedures required to reduce door-to-balloon times from:
http://en.wikipedia.org/wiki/Door-to-balloon#Improving_door-to-balloon_times
2.) Name and Description of Application:
Our application is named: „Project PAMI‟. This stands for „Primary Acute Myocardial
Infarction‟. Primary Acute Myocardial Infarction accounts for the greatest percentage of deaths
among cardiac-disease related deaths and can be significantly reduced by reducing the „door-to-
balloon time‟.
Application Description:
Our application deals with improvement in two particular areas of the cath-lab system,
replacing the normal Remote-Based User Interface with NUI and therefore, significantly
reducing the „door-to-balloon‟ time.
a) The User Interface for Video Analysis: The current video-analysis tools in a modern
cardiac cath-lab are significantly disorganized and „time-consuming‟. Several factors attribute to
this:
(i) The zoom in and scroll image tools are not readily available at the remote. For an analysis, an
additional person is required to work from the console, which is again generally in a separate
room. This often results in waste-age of „door-to-balloon‟ time. We plan to improve this by
providing two gesture recognize-able functions:
When both the hands are brought closer it‟s a zoom in and when they are taken away it‟s a
zoom out gesture. This way the physician can zoom in/out a particular frame in the scan to
observe the defects more carefully.
In addition, a cursor is provided after the zoom in gesture to scroll around the zoomed
segment. This cursor can be used for scrolling by tracking the movement of the using a „point‟
gesture. The direction point will cause the scrolling to occur at a pre-determined speed which can
be changed by the physician if required.
(ii) Standard controls that are provided on the remote are not sufficiently robust. The time delay
between the „button-press‟ and the „acknowledgement‟ on screen is significant. This causes
further increase in „door-to-balloon‟ time for a procedure, especially if the desired frame is
missed during the course of the procedure.
6. We plan to make it more natural by providing a push gesture, point gesture and a swipe-left,
swipe-right gesture in order to navigate through the frames obtained.
(b) User interface for C-Arm movement: C-Arm movement is in general done by a
radiologist technician. Most of the C-Arm movement is highly repetitive for a common
procedure. There are 5 common „C-Arm Angiographic views‟. We plan to give activate voice
recognition on basis of a particular gesture in order to navigate to a particular view.
For more clarification: Perform Gesture A Voice Recognition is activated „Request „RAO
20 Caud 20‟ is a sample procedure someone using our gadget would have to do.
The five common angiographic views are:4
i) „RAO 20,Caud 20‟
ii) „PA 0, Caud 30‟
iii) „LAO 50, Caud 30‟
iv) „LAO 50, Cran 30‟
v) „PA 0, Cran 40‟
Each of these views will be enumerated with a voice command, and Voice Recognition will be
activated using a gesture command.
[4] http://www.askdrwiki.com/mediawiki/index.php?title=Coronary_Angiography
3.) Originality and Innovation:
The C-Arm movement based on Voice Recognition while controlling the Voice
Recognition via simple gestures is original for this field.
This is possibly the first time the CT-scan and catheterization lab have been influenced
significantly by the use of Kinect‟s revolutionary NUI interface.
7. 4.) Pre-existing Source Code:

System Control
Physical Interface Blocks Software Architecture
•Geometry block •User Interface Layer
•X-Ray Generation Block •Application Layer
•Image Detection Block •Technical Layer
•Image Processing Block •Embedded Software Layer
•Image Display Block
•Image Storage Block
Application area: The User Interface Layer: This layer contains the software for the GUI
(the software interface on the data monitor and the Xper module) and NGUI (Geometry and
Review modules, view pads, etc). It translates user actions to elements (commands) of the
interface provided by the application layer. Furthermore, it provides information to the user
about the system state, based on state information provided on the interface of the application
layer. The UI layer is notified about changes in the application state by means of events
generated by the application layer. The UI layer is where a majority of programming tools and
interfaces are readily available for those who want to develop applications for Philips C-Arm.
This layer‟s access is sufficient for our requirements and its documentation is readily available in
two forms as open-source.

booklet.(Freely available)
8. 5.) Unique NUI Features:
We intend to design a multimodal system (speech + gesture) using the following NUI features in
our application.
i) Skeleton tracking:
We use the skeleton tracker of Microsoft Kinect SDK to track few vital skeletal joints of the
doctor performing the CT scan. We plan to track right hand to use it as a mouse control. The
position of the right hand is shown on the screen and the doctor can move his hand to select
predefined control buttons that are displayed on the screen.
ii) Push:
When the right hand is moved slightly in the direction of depth (i.e,z axis) a push is detected.
When a push action is performed on any one of the predefined buttons displayed on the screen,
the action is taken accordingly. For example, there are two buttons displayed on the screen: 1)
Start and 2) Stop. The doctor can move his hand to focus the mouse pointer on the start/stop
button and perform a push action. This will start/stop recording the CT Scan.
iii) Swipe right/Swipe left:
When the hand is moved swiftly to left/right a swipe left/right is detected. This gesture can be
used to navigate through the frames back and forth.
iv) Zoom-In and Zoom-Out:
When both the hands are brought closer it‟s a zoom out and when they are taken away it‟s a
zoom in gesture. This way the physician can zoom in/out a particular frame in the scan to
observe the defects more carefully. In addition, a cursor is provided after the zoom in gesture to
scroll around the zoomed segment.
v) Audio recognition:
This is the secondary mode of interaction, gesture being the first. The doctor will be able to
perform various actions on the CT recording just by calling out the appropriate word/sentence
like for ex “delete from start to this” will delete all the frames from the beginning to the current
one.
9. 6. Usability
The application should be very intuitive and easy to use, since, we want to minimize the
„door-to-balloon‟ time. All of the features mentioned in the NUI section, are simple to use and
very intuitive.
On consultation with doctors at Krishna Institute of Medical Sciences, while proposing
this gadget, their thoughts were that it would greatly simplify things. The gestures are simple to
use and would be recognizing a single person only, by taking advantage of skeletal tracking
provided by Kinect. The C-Arm movement would be easy to perform with Voice Recognition
stepping in only when actually required.
A one week training period might be required however, to let the physicians get
accustomed to the changes in the interface.
7.) Presentation and Polish:
Some of the things which we‟d like to stress upon for our presentation would be:
a) Case studies showing the importance of door-to-balloon time and their influence on patient
mortality rates.
(i) „Using a multivariate logistic regression model, the adjusted odds of in-hospital mortality did
not increase significantly with increasing delay from MI symptom onset to first balloon inflation.
However, for door-to-balloon time (median time 1 hour 56 minutes), the adjusted odds of
mortality were significantly increased by 41% to 62% for patients with door-to-balloon times
longer than 2 hours.‟
Source: http://jama.ama-assn.org/content/283/22/2941.full
b) Possible improvements in door-to-balloon time because of „our gadget‟.
(i) In multivariate analysis, six strategies were significantly associated with a faster door-to-
balloon time. These strategies included having emergency medicine physicians activate the
catheterization laboratory (mean reduction in door-to-balloon time, 8.2 minutes), having a single
call to a central page operator activate the laboratory (13.8 minutes), having the emergency
department activate the catheterization laboratory while the patient is en route to the hospital
(15.4 minutes), expecting staff to arrive in the catheterization laboratory within 20 minutes after
being paged (vs. >30 minutes) (19.3 minutes), having an attending cardiologist always on site
(14.6 minutes), and having staff in the emergency department and the catheterization laboratory
10. use real-time data feedback (8.6 minutes). Despite the effectiveness of these strategies, only a
minority of hospitals surveyed were using them.

One of these methods namely, „expecting staff to arrive in the catheterization laboratory 20
minutes after being paged‟ will be made much easier, since with lesser requirement of staff,
lesser mean delay in arrival of staff can be expected. More detailed case studies dealing with the
same would be appropriate as well.
c) Case studies showing the effects of radiation in the catheterization lab in hospitals.
