Radiation therapy is used to kill cancer cells; however, normal cells are also damaged in the process. Currently, therapeutic doses of radiation can be targeted to tumors with great accuracy using linear accelerators in radiation oncology; however, when irradiating using external beam radiotherapy, the beam will always need to travel through healthy tissue, and the normal liver tissue is very ...
Diagnostic angiography images are captured of the aorta to determine the location of the patient's renal arteries, so the stent-graft can be deployed without blocking these. Failure to achieve this will cause kidney failure. With most devices, the "main body" of the endograft is placed first, followed by the "limbs" which join the main body and ...
