Inverse Planning
Inverse planning is a technique used to design a radiotherapy treatment plan. A radiation oncologist defines a patient's critical organs and tumour and gives target doses and importance factors for each. Then, an optimisation program is run to find the treatment plan which best matches all the input criteria.
The term "inverse planning" is somewhat of a misnomer; it was devised in contrast to the manual trial-and-error process known in oncology as "forward planning". It has stuck for historical reasons. Outside of the field of oncology, this procedure would be better described as "automated planning".
HIPO (Hybrid Inverse Planning & Optimization), developed by Pi-Medical Ltd., is one algorithm.
