echocardiogram uses sound waves to produce images of the heart. In this procedure, a radiologist uses a transducer (a transducer is an electrical device that converts a signal from one form of energy to another form of energy) to transmit and receive ultrasound waves, which are reflected when they reach the edge of two structures with different densities. The image produced by an echocardiogram shows the edges of heart structures, but it cannot measure the speed of blood flowing through the heart. Doppler
Radiologist Radiology is a branch of medical science. It uses x-rays as well as other types of technology to create images of the internal workings of the body. Radiologists use these images, which use a wide variety of imaging technologies, to diagnose and treat diseases. A radiologist’s job is to use radiant energy to create images from which to diagnose patients. As soon as this is done, the radiologist then communicates their findings to the patient’s physician; so a treatment plan can be made
chemotherapy, cancer, renal and trauma services etc. The QueenElizabethHospital has been ranked at three stars in 2001-02 and treats over 650,000 patients each year. The two aspects of physics which I investigated were: * Gamma Camera * Ultrasound Applications of physics. * Gamma camera The first application of physics that I witnessed was the Gamma camera in the nuclear medicine department. This basically involves the patient being injected with a gamma emitting-isotope, this
conventional radiography, and should be restricted to critically ill children who may need neurosurgical intervention (21). Iterative reconstruction and all appropriate dose reduction techniques should be used to reduce radiation exposure (22). Non-contrast-enhanced CT is the imaging modality of choice for suspected head trauma, and has the advantage of being readily accessible with relatively quick acquisition times (1, 23, 25). It is highly sensitive and specific for the detection of acute cranial injury

Medical imaging, as we all know, is the process of taking images of various parts of the human body for diagnostic and surgical purposes. Some of the popular medical imaging modalities are X-ray radiography, Magnetic resonance imaging, Medical ultrasound, Computed tomography etc. Since, these images contain clinical data of extreme importance for treatment follow-ups and are acquired at cost of radiation exposure, infrastructure, money and time involved. Thus, once acquired, the medical imaging data
of methods and in a number of different styles. The Digital image processing allows one to enhance image features of interest while attenuating detail irrelevant to a given application and then extract useful information about the scene from the enhanced image. Digital image processing is the use of computer algorithms to perform image processing on digital images. Digital image processing has the same advantages over analog image processing as digital signal processing has over analog signal processing
become one of the most stigmatizing bodily characteristics in our culture (Brink, 1994). In the Western culture, thinness does not just mean the size of the body, but it is associated with such qualities as being healthy, attractive and in control. In contrast, a fat body is viewed as a sign of poor health, inefficiency and lack of personal will (e.g. Kissling, 1991; Ogden, 1992; Cooper, 1998). Resent research has shown that the social stigma associated with obesity can have serious consequences for an
