1) What is a medical imaging device?

Medical imaging is the technique and process used to create images of the human body for clinical purposes. Medical imaging seeks to reveal, diagnose, or examine a disease. Some examples of medical imaging device are CT scans, MRIs, an ultrasound, and a PET scan.

2) Compare and Contrast the following: X-Ray, Digital Subtraction Angiography, PET, Ultrasound, and MRI in terms of uses, how they work, etc.

Radiography is the technique of examining the body by directing X-ray through it so can produce images on photographic plates or fluorescent screens. The main uses for x-rays to diagnosis disorders such as broken bones, gastric ulcer, to detect foreign objects such as glass or wooden pieces in different parts on the body, and x-rays are also used in dentistry to detect dental caries and periodontal disease. Positron Emission Tomography (PET) scan is an imaging technique that allows physicians to examine many organs of the body and is helpful in diagnosing many diseases, such as cancer. Special characteristics of the PET scan is that it is able to perform whole body scans on patients, useful in detecting early stage cancer, produces clear images, and can effectively pinpoint the source of the cancer. The ultrasound machine produces real time diagnostic pictures by using high frequency sound waves to echo off the body structure without harmful radiation. Uses of the ultrasound scan is to assess the growth and condition of baby inside he womb, breast scanning, abdominal imaging, and thyroid imaging. Being equipped with a powerful high field Magnetic Resonance System, Union MRI Centre provides a superior and reliable imaging service. Highly detailed diagnostic images can be produced, with our noninvasive radio wave and advanced computer system, for all parts of the body especially the brain, heart, pine, joints, soft tissues and blood vessels.
