This process was called inverse planning. From the beginning it was clear that IMRT approach need a different mathematical methods and algorithms to evaluate and to minimize the ...
Witryna1 gru 1999 · IMRT (NOMOS Peacock system; Sewickley, PA) has evolved from computer tomography (CT) concepts. A CT scan delivers uniform radiation exposure to the patient as it rotates around the patient's contour in a slice-by-slice fashion.
