Importance of Technological Advancements in Understanding of Human Internal Systems

Description of Technique/Technology:

A computed tomography (CT) scan is a technique used for medical X-ray imaging that allows cross-sectional images of the interior body to be computerized. The images are then combined into a three dimensional image via the computer and provides detailed information. In order to capture these images, a patient must lie on a table inside an X-ray tube that rotates around the desired location while electronic sensors capture the patterns of electrical impulses. These patterns are then transferred to a computer where the data is integrated into a three dimensional image. With medical technology, the images can be projected and photographed in order to provide accurate results (“CAT Scan,” 2012).

2 uses of this technology/technique in the field of medicine * A CT Scan can be used as an extremely accurate way of detecting diseases or injuries in the body such as: traumatic injuries (blood clots or skull fractures), tumors, and infections. Other abnormalities often found include brain aneurysms, stroke, tumors of the brain, as well as tumors or inflammation of the spine (Stöppler, 2012).

* CT images are also used as basis for planning radiotherapy cancer treatment. CT is also often used to follow the course of cancer treatment to determine how the tumor is responding to treatment (Stöppler, 2012).

2 social/medical benefits
* In the field of Paleontology, CT Scans allow paleontologists to analyze the interior structures of fossils without breaking or damaging the fossils. Recent studies have revealed a dinosaur from the Late Cretaceous Period with complex tubes and chambers within the crest (Gallagher, 2012).

* CT images of body structures can guide radiologists in performing procedures such as: biopsies of suspected cancers, removal of internal body...
