Three-dimensional echocardiography allows clinicians to visualize the entire heart in a single image, unlike two-dimensional echocardiography. It has several advantages over 2D echocardiography for diagnosing congenital heart disease, including the ability to view cardiac structures in three dimensions which clarifies spatial relationships. While 3D echocardiography is limited in newborns by fast heart rates, it has proven useful for assessing complex congenital heart lesions, quantifying cardiac valves and ejection fraction, and aiding pre-surgical planning. The technology continues to advance and may enable applications like 3D printing of artificial heart valves in the future.

Join Dr. Dinesh Thavendiranathan of the University of Toronto for a discussion on 3D volume echocardiography in the left heart. Hear how volume echocardiography enables the acquisition of an entire volume of the heart in a single full cardiac cycle and facilitates faster and more accurate analysis via full automation of endocardial contours. Also learn about workflow improvements, more reproducible echo exams and ways to save costs
Radiology procedures such as ultrasound, MRI or CT scans are very useful in detecting and diagnosing cardiovascular anomalies. Fluoroscopy is mostly used in cardiac intervention.
Echocardiographic guidance is critical for procedural success of paravalvular leak closure. Transesophageal echocardiography (TEE) and particularly three-dimensional echocardiography represent the gold standards. Fusion imaging provides real-time integration of three-dimensional echocardiography and X-ray fluoroscopy and can further facilitate spatial orientation, wire placement and device deployment. Intracardiac echocardiography (ICE) is a secondary approach possibly beneficial in selected cases.

The assessment of right ventricular (RV) function remains one of the
most challenging and technically difficult tasks in echocardiography.
There are many anatomic and functional peculiarities that distinguish
the RV from the left ventricle, which pose significant challenges to the
conventional echocardiographic assessment of RV function and preclude the extrapolation of the knowledge and evidence accumulated
for the left side to the RV.
In the last years, RV strain imaging emerged as a superior metric of
RV systolic performance, overcoming some of the limitations of conventional echocardiographic parameters.1 RV longitudinal strain can
be measured by both tissue Doppler imaging and speckle-tracking
echocardiography (STE) techniques. The advantages of using the
speckle-tracking over the Doppler tissue imaging technique rely on
the independency of the measurements from the angle of insonation
and better reproducibility. Moreover, RV longitudinal strain measured using 2D STE has shown to be clinically useful in patients with
arrhythmogenic RV cardiomyopathy,2 and to have strong prognostic
value in a variety of diseases3 and also in the general population of
patients undergoing clinically indicated echocardiography.4

Abstract: Prosthetic paravalvular leaks (PVL) is an uncommon but serious complication after surgical valve replacement. Although surgery has been the traditional treatment of choice in hemodynamically significant PVL, percutaneous transcatheter closure is emerging as a novel and less invasive option for patients with high operative risk. Cardiac imaging, especially two- and three-dimensional transoesophageal echocardiography, plays an essential role in the diagnosis, guidance of intervention and subsequently in the evaluation of the outcomes of the procedure. The aim of this manuscript is to review the role of cardiac imaging techniques in the interventional management of patients with symptomatic PVL.
Digital Image Processing Assessment in Multi Slice CT Angiogram using Liner, ...IJERA Editor
Nowadays with heart diseases most of peoples are dying lock process to find problem agile fashion in remote areas. In this research help to peoples who are staying remote also to find problem in heart on which location and how much problem to near and finally gives best analysis methodology for automated analysis for MultiSlice CT Angiogram images. Multi slice CT scanner is used to identify heart disease. Multi-detector CT is considered convenient and reliable non-invasive imaging modality for assessment of human angiogram 3D images. Automatic hart segmentation from Computed Tomography (CT) is highly demanded. Accurate hart segmentation is a crucial for computer-aided heart disease diagnosis and treatment planning. After segmentation and future extraction then identify whether the patient angiogram waveform has disease or not. For that, Support Vector Machine method is used to confirm the presence of disease. Neural Networks can solve different types of nonlinear problems in image classification and retrieval process. After that majorly focus on research learning methodologies for improve performance of the Multi Slice CT Angiogram images. So, in this research is summarizing the problem with liner of RBF neural network, Non-Liner SVM and RBF NN with liner and non-liner. Final, RBF NN with liner and non-liner provided more value and proved as best compare with other existing methodologies. This methodology consumes less time for both learning as well as testing comparatively than any other methods like back propagation. This issue drastically improves the estimation efficiency and accuracy for real time 128, 256 slices CT scan angiogram images.
Lung cancer is one of the leading
causes of mortality in every country, affecting
both men and women. Lung cancer has a low
prognosis, resulting in a high death rate. The
computing sector is fully automating it, and the
medical industry is also automating itself with the
aid of image recognition and data analytics. Lung
cancer is one of the most common diseases for
human beings everywhere throughout the world.
Lung cancer is a disease which arises due to growth
of unwanted tissues in the lung and this growth
which spreads beyond the lung are named as
metastasis which spreads into other parts of the
body.
The objective of our project is to inspect accuracy
ratio of two classifiers which is Support Vector
Machine (SVM), and K Nearest Neighbour
(KNN) on common platform that classify lung
cancer in early stage so that many lives can be
saving. The experimental results show that KNN
gives the best result Than SVM. This report
discusses the Implementation details of our
project.
We have done data preprocessing, data cleaning
and implements machine leaning algorithm for
prediction of lung cancer at early stages through
their symptoms. We have used both classification
algorithms to find or predict the accuracy ratio.
Lung cancer is identified as the most common
cancer in the world that causes death. Early
detection has the ability to reduce deaths by 20%.
In the current clinical process, radiologists use
Computed Tomography (CT) scans to identify
lung cancer in early stages. Radiologists do so by
searching for regions called ‘nodules’, which
correspond to abnormal cell growths. But
identifying process is time consuming, laborious
and depends on the experience of the radiologist.
Hence an intelligent system to automatically
assess whether a patient is prone to have a lung
cancer is a need.
This paper presents a novel method which use
deep learning, namely convolutional neural
networks (CNNs) to identify whether a given CT scan shows evidence of lung cancer or not. The
implementation uses a combination of classical
feature-based candidate detection with modern
deep-learning architectures to generate excellent
results better than either of the methods. The
overall implementation consists of two stages.
Nodule Regions-of-Interest (ROI) extraction and
cancer classification. In nodule ROI extraction
stage, we select top most candidate regions as
nodules. A combination of rule based image
processing method and a 2D CNN was used for
this stage. In the cancer classification stage, we
estimate the malignancy of each nodule regions
and hence label the whole CT scan as cancerous
or non-cancerous. A combination of feature based
eXtreme Gradient Boosting (XGBoost) classifier
and 3D CNN was used for this stage. The LUNA
dataset and LIDC dataset were used for both
training and testing. The results were clearly
demonstrated promising classification
performance. The sensitivity, accuracy and
specificity values obtained for

Perspective
echocardiography. The technological limitations were too great
to perfect 3D echo in the early eighties. However, Moore law
beauty is present in the field of echocardiography. With the
advent of advanced matrix array transducers, three- dimensional
echocardiography became a reality for the cardiovascular
community in the early 90s.
Volumetric Acquisition
Three-dimensional echocardiography has many advantages
over 2D echocardiography. 2D echocardiography has many
technological limitations and barriers to gathering effective
clinical data on congenital heart disease. Three-dimensional echo
allows images to be presented in all three spatial dimensions:
height, width, and depth. Today, 3D echo offers the ability to
visualize the whole heart in one full volume image capture. Once
this image is acquired, a clinician can cut and crop, the data
necessary for diagnosis of congenital heart disease. The key to
good image capture is avoiding breathing artifacts, or extremely
high heart rates. Due to this limiting factor, 3D echo is not
applicable for neonate echo exams now.
Modes of Acquisition
There are a few dynamic modes of 3D echo that can be used in
either transthoracic or transesophageal modalities. The first mode
is live 3D echo. This mode allows for real time visualization of
cardiac structures. The next mode is narrow angle or zoom mode.
This mode allows for a focused examination of a cardiac structure.
There is reduced spatial resolution with this methodology. In
addition, full volume mode is best suited for performing ejection
fraction measurements. 3D color Doppler provides utility for the
grading of stenosis, as well as, assessing cardiac murmurs.
Atrioventricular valves
Three–dimensional echo is uniquely suited for the
quantification of vavular disease due to its way of imaging
non-planer valve leaflets, chordal structures, and papillary
muscles. Three-dimensional echo is vital for the presurgical and
postsurgicial follow up of cardiac valve replacements. Morever;
three-dimensional color Doppler has utility for assessing mitral
regurgitation. 3D echo technology made the TAVR procedure a
success story for interventional cardiology.
Congenital heart lesions
3D echo has demonstrated great utility in the diagnosis of
complex congenital heart lesions. In addition, 3D echo clarifies
the complex interspatial relationship between normal cardiac
anatomy and congenital septal defects. This knowledge is vital to
thepresurgicalplanningprocessforinterventionalcardiology.The
one current technical limiting factor in neonate echocardiography
is the fast heart of newborn babies. 3D echo has difficulty trying
to process those fast frame frames into an interpretable image.
Ejection fraction quantification
3D echo has improved the ability to acquire a more accurate
and reproducible ejection fraction. With 3d echo, there are no
geometrical assumptions for calculating an accurate left ventricle
volume. This is a great benefit for the pediatric echo community.
Future Directions of 3D echo
The future capabilities of this technology are likely to be just as
amazing as its initial rollout a decade ago. There will continue to be
technological advancements in transducers design, quantification
packages etc. In addition, the rise of three-dimensional printing
should create excellent symettery with 3D echo ultrasound. It’s
wholly conceivable a decade from now that 3d echo volumes,
will be fed, into a 3D printer for designing artificial heart valves,
patches, etc. The era of bio–printing of heart valves will arrive in
the twenty-first century.
Introduction
Three-dimensional echocardiography is a diagnostic imaging
tool used to assess and quantify cardiac anatomy and function.
The unique ability of visualizing cardiac structures in three-
dimensional ultrasound is obvious in 2016. Moreover, three-
dimensional echo is performed with either transthoracic or
transesophageal methods. This article will present an overview of
3d echo capabilities and limitations, as well as, a look at its future
applications.
3D Echocardiography
Over the past twenty-five years, the field of echocardiography
has experienced dramatic technological advancement in image
quality, portability, and quantification capabilities. Further, a
great deal of time and investment dollars was allocated to 2D
