Principles of mdct
MDCT provides high resolution images through rapid acquisition of multiple slices during a single rotation. It uses multiple detector arrays rather than a single row, allowing acquisition of more data in less time. Image reconstruction involves back projection, iterative, or analytical methods to assign CT numbers based on x-ray attenuation. Applications include angiography, cardiac imaging, and virtual endoscopy due to improved temporal and spatial resolution compared to earlier CT technologies.
Mri coils
MRI coils play an essential role in generating MRI images. There are several types of coils that work together, including gradient coils, shim coils, and radiofrequency (RF) coils. Gradient coils use magnetic fields to spatially encode the MRI signal and allow for imaging in different planes. RF coils transmit and receive radiofrequency signals to and from the body, converting these signals into data used to construct the final images. Different coil designs, such as volume, surface, and phased array coils, are optimized for imaging different body regions and provide better signal-to-noise ratios.
Fluroscopy

Modern fluoroscopy systems use digital image processing and recording techniques to provide real-time visualization of internal structures during medical procedures.
Computer Tomography (CT Scan)
Computed tomography (CT scan) is a medical imaging procedure that uses computer-processed X-rays to produce tomographic images or 'slices' of specific areas of the body. These cross-sectional images are used for diagnostic and therapeutic purposes in various medical disciplines.
CT ITS BASIC PHYSICS
Computed tomography (CT) uses computer-processed X-rays to create cross-sectional images of the body. CT works by rotating an X-ray tube and detectors around the patient, acquiring multiple transmission measurements at different angles to reconstruct a 3D image. Image reconstruction involves algorithms like back projection and filtered back projection that use the transmission data to calculate the attenuation coefficients of different tissues and generate tomographic images representing slices of the body. CT numbers, measured in Hounsfield units, provide standardized values related to tissue density and visibility.

This results in a signal dependent on T1 and T2 properties. SSFP provides high signal-to-noise ratio and is used for cardiac imaging, flow imaging, T1/T2 mapping, and whole body imaging, but is sensitive to field inhomogeneities. Sensitivity encoding (SENSE) uses knowledge of multiple receiver coils' spatial sensitivities to unfold aliased signals and reduce scan time.
Multi spectral imaging
A multispectral image is one that captures image data from two or more ranges of frequencies along the spectrum, such as visible light and infrared energy.
In multispectral images, the same spatial region is captured multiple times using different imaging modalities.
MRI Presentation Final
Magnetic Resonance Imaging (MRI) is a medical imaging technique that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body. There are different types of MRI machines, including closed, open, and upright configurations. MRI is used to diagnose conditions such as brain tumors, hemorrhages, and multiple sclerosis. It works by aligning hydrogen atoms in the body using magnetism and radio waves, and analyzing the signals produced to form images of tissues and structures. Advantages include a lack of radiation and ability to image soft tissues, while disadvantages include cost and potential incompatibility with metallic implants.

Ultra Low Power Design and High Speed Design of Domino Logic Circuit
The tremendous success of the low-power designs of VLSI circuits over the past 50 years has significant change
in our life style. Integrated circuits are everywhere from computers to automobiles, from cell phones to home
appliances. Domino logic is a CMOS based evolution of the dynamic logic techniques based on either PMOS or
NMOS transistors. Dynamic logic circuits are used for their high performance, but their high noise and
extensive leakage has caused some problems for these circuits. Dynamic CMOS circuits are inherently less
resistant to noise than static CMOS circuits. In this paper we proposed different domino logic styles which
increases performance compared to existing domino logic styles. According to the simulations in cadence
virtuoso 65nm CMOS process, the proposed circuit shows the improvement of up thirty percent compared
existing domino logics.

Mobile application processors are soon to replace desktop processors as the focus of innovation in microprocessor technology. Already, these processors have largely caught up to their more power hungry cousins, supporting out-of order execution and multicore processing. In the near future, the exponentially worsening problem of dark silicon is going to be the primary force that dictates the evolution of these designs. We have argued that the natural evolution of mobile application processors is to use this dark silicon to create hundreds of automatically generated energy-saving cores are called conservation cores, which can reduce energy consumption by an order of magnitude. Conservation cores(C-cores) try to solve utilization wall and consequently Dark Silicon issues.Greendroid is a development library for the android platform. It is intended to make UI developments easier and consistent through your applications. This paper describes Greendroid, a research prototype that demonstrates the use of such cores to save energy broadly across the hotspots in the android mobile phone software stack.

Aneshesia
This document discusses different types of anesthesia. It describes local anesthesia as affecting a small area while the patient remains conscious. Regional anesthesia affects a larger area like a limb but the patient stays conscious. General anesthesia puts the patient into a medical coma to perform major surgery. It also discusses how anesthesia works, including using drugs to block nerve signals and relax muscles. Modern ventilators help regulate patient breathing during sedation. The document outlines the four stages of anesthesia from initial drug administration to loss of consciousness or circulation.
Cobalt 60
The document discusses cobalt-60 and its use in external beam radiation therapy. Cobalt-60 is a radioactive isotope that decays through beta decay, emitting two gamma rays with energies of 1.17 and 1.33 MeV. It is used as a sealed source in teletherapy units, where its gamma rays are aimed at cancerous tumors from multiple angles to destroy cancer cells. The main components of a cobalt-60 machine are the head containing the cobalt-60 source, a collimator to shape the beam, a gantry that rotates around the patient, and a patient support assembly. Cobalt-60 therapy has been used for almost 60 years to treat various cancers throughout the body due its precision and effectiveness.
Flouroscopy
Fluoroscopy uses X-rays to produce real-time moving images and is displayed on a monitor. It works by passing an X-ray beam through the body. The image intensifier converts the X-ray image into a brighter visible light image. It contains a photocathode that emits electrons when hit by X-rays, and an output phosphor that converts the electrons back into a magnified visible light image. This process amplifies and multiplies the number of photons. Fluoroscopy provides brighter images than older techniques and allows examinations to be done without complete darkness. It is used in procedures like cardiac catheterization, joint imaging, and IV catheter placement.
Gamma Camera
The gamma camera, also known as the Anger camera, was developed in 1957 to detect gamma rays emitted from radiotracers introduced into the body. It uses a collimator, sodium iodide crystal, photomultiplier tubes, preamplifiers, and other components to detect gamma rays and determine their position, which can then be plotted and displayed. The gamma camera is used to scan the whole body and produce anatomical images using computer reconstruction of the gamma ray emission data.
LINAC
A linear accelerator is a medical device used in radiation therapy to treat cancer. It contains components like a radio frequency power source, modulator, electron gun, and accelerator guide. Electrons are injected into the accelerator guide in pulses from the electron gun and accelerated using high-frequency electromagnetic waves supplied by the RF power source down the guide to produce a beam of x-ray radiation to treat tumors. Linear accelerators are used to treat cancers of the bone, head, neck, pelvis, and thorax by emitting precisely targeted beams of radiation.
PET
PET (positron emission tomography) is a noninvasive medical imaging technique that measures metabolic activity in the human body. It works by injecting a radioactive tracer labeled with a positron-emitting isotope. The tracer accumulates in tissues and organs with high metabolic activity. When the radioactive isotope decays, it emits positrons that interact with electrons, producing pairs of gamma rays emitted in opposite directions. These gamma rays are detected by a ring of sensors, allowing reconstruction of 3D images showing tracer concentration in different tissues. PET scans are useful for diagnosing and monitoring conditions affecting the brain, heart, cancer, Alzheimer's disease, and some neurological disorders.
SPECT
SPECT is a nuclear medicine imaging technique that uses gamma rays to create 3D images of the distribution of radiopharmaceuticals in the body. It employs a gamma camera that rotates around the patient to detect gamma rays emitted by radiotracers administered to the patient. Common radiotracers used in SPECT include technetium-99m, technetium-201, iodine-123, indium-111, and xenon-133. The gamma camera contains thallium-activated sodium iodide crystals that convert gamma rays into visible light. SPECT is used in cardiac, bone, renal, gastric, hepatobiliary, thyroid, pulmonary, and brain imaging.
X ray
This document summarizes the key components and functions of an x-ray machine. It discusses x-radiation and its properties. It then lists and describes the major parts of an x-ray machine including the x-ray tube, high voltage transformer, collimator, grid, Bucky table, and radiographic film. It also explains the purpose and workings of additional components like the auto transformer, x-ray console controls, and collimator.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

- 7. Problem Over Come: PMT’s were replaced by Photo cathode assembly. Advantage: Smaller in size Cheaper in cost. No need of separate supply.
- 8. 1) Sodium iodide (Na I). 2)Bismuth Germinate (BGO). 3)Cesium iodide (CI). 4)Cadmium thungstate (CdWO4).
- 9. 2) Gas FILLED: It has the same Efficiency as Scintillation crystal . We have to do it Air lock. * They are constructed with large metallic chambers, With baffles space approximately 1mm. * Each small chamber function as a separate radiation detector.
