Benefits and Applications

   Since the invention of the conventional CT, the technology has been used for array of medical procedures such as "tissue biopsy³, drainage of fluid such as in cysts, abscesses⁴, lymphoceles⁵, bilioma⁶, and hematomas⁷, pain therapy, study of knee or elbow motion, swallowing, and also a way to locate and stop excessive bleeding" (Imaginis Corporation).

   Early day biopsy would consist of a patient being struck with a needle as it is guided by the CT scan. The technician would have to stop between each image to reset as well as to move the patient accordingly (MedlinePlus Medical Encyclopedia: biopsy). With more improvements to the CT scanner, the difficulty has greatly been reduced. This is a great step towards being fully automated as well as entirely painless. The machine is also used to treat spiral injuries as well (JC, BC and RJ). A ruptured disc of the invertebrate was often referred to as an open surgery. Now, however, the surgeon can most often use micro-surgery to reset the disc with the aid of a CT scanner (Imaginis Corporation). Thus, the usage of CT or CAT scan greatly reduces the risks that are associated with open surgery.
