Minibeam Collimator That Improves Cancer Radiation Therapy
High grade brain tumors are incurable, are treated with conventional radiation therapy techniques, but are associated with considerable side effects. Dr. Kundapur's team have developed an effective way of treating these tumors through designing and constructing a collimator which produces very narrow beams of radiation called mini-beams (MBRT) using low energy x-rays. The advantage of using MBRT is that a therapeutic radiation dose can be delivered to the tumor while sparing normal brain. They have tested this on mice brain tumors with no damaging effect on brain cells and have initiated a large animal study using high energy mini-beam irradiation techniques.
