SPECT, the acronym for Single Photon Emission Computed Tomography, is a nuclear medicine imaging modality, giving information about a patient?s specific organ or body system. The patient is injected with a radiopharmaceutical, which will emit Gamma rays. The radio activity is collected by an instrument called gamma camera and the image is reconstructed. SPECT is used to make three dimensional images of the heart, to perform brain studies and for skeletal scintigraphy. It is reasonable to speculate about a constant by perhaps a slower rate of in ....etc

ABSTRACT

The basic principles of Dual Energy X-ray Absorptiometry have been discussed in this presentation. DEXA is a instrumental technique used to measure bone mineral density (BMD), which is the widely accepted indicator of bone strength. DEXA scanner is the most widely used modern electronic machine to diagnose the disease osteoporosis, the thinning of bones. Human body being a heterogeneous system, use of a dual energy, rather than single energy, X-ray source is necessary for scanning. The interaction of the sample wi ....etc

Definition

With the proliferation of portable electronic devices, power efficient data transmission has become increasingly important. For serial data transfer, universal asynchronous receiver / transmitter (UART) circuits are often implemented because of their inherent design simplicity and application specific versatility. Components such as laptop keyboards, palm pilot organizers and modems are few examples of devices that employ UART circuits. In this work, design and analysis of a robust UART architecture has been carried out to minimiz ....etc

1. INTRODUCTION

Emission Computed Tomography is a technique where by multi cross sectional images of tissue function can be produced , thus removing the effect of overlying and underlying activity. The technique of ECT is generally considered as two separate modalities. SINGLE PHOTON Emission Computed Tomography involves the use single gamma ray emitted per nuclear disintegration. Positron Emission Tomography makes use of radio isotopes such as gallium-68, when two gamma rays each of 511KeV, are emitted simultaneously where a positron from ....etc
