Automation of Radiation Treatment Planning For Cervical Cancer
… The mortality rate can be reduced if radiation treatment becomes widely available. However, due to the lack of radiation treatment facilities and human resources, many cervical cancer patients in Africa are not able to receive timely treatments or advanced therapies. To increase the availability …

Segmented breast treatment planning incorporating 4D data acquisition
Conventional 3-D external beam radiation therapy for breast cancer, although a vast improvement over traditional therapy, does not take into account respiratory motion. With breast cancer patients, this motion can expose healthy tissues, such as the lungs, to higher doses than expected. More …
