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.

Famous quotes containing the words inverse and/or planning:
“Yet time and space are but inverse measures of the force of the soul. The spirit sports with time.”
—Ralph Waldo Emerson (1803–1882)
“Play for young children is not recreation activity,... It is not leisure-time activity nor escape activity.... Play is thinking time for young children. It is language time. Problem-solving time. It is memory time, planning time, investigating time. It is organization-of-ideas time, when the young child uses his mind and body and his social skills and all his powers in response to the stimuli he has met.”
—James L. Hymes, Jr. (20th century)
