Major advances in radiation therapy for cancer treatment

Radiation therapy has advanced dramatically in the past few decades and the rate of change is increasing rapidly. Innovations as a result of engineering and computer advances along with conceptual advances are making a dramatic difference.

Some of the new technologies include improved computer assisted treatment planning (smarter and faster and has more capability like auto-contouring, smart segmentation and improved algorithms) , continuous imaging guidance (fluoroscopic, stereoscopic, and cone beam CT), robotics, more precision, higher dose rates, gating of the beam to track moving targets, stereotactic treatments and hypofractionation (or giving much larger doses fewer times) – all with the goal of greater efficacy, less side effects and less time under treatment.
