Incorporating deliverable monitor unit constraints into spot intensity optimization in IMPT treatment planning
Purpose: This study is to investigate the feasibility and impact of incorporating deliverable monitor unit (MU) constraints into spot intensity optimization in intensity modulated proton therapy (IMPT) treatment planning. Methods: The current treatment planning system (TPS) for IMPT at our institution disregards the deliverable MU constraints in the spot intensity optimization (SIO) routine. It...

Radiation therapy is a non-invasive treatment modality for cancer patients. Radiation therapy treatment planning for cancer patients provides many challenging optimization problems. Various variables of a treatment plan need to be optimized so that the resulting plan can kill all cancerous cells while minimizing damage on the patient’s normal tissues. Intensity modulated proton therapy (IMPT) h...
متن کاملEvaluation of treatment planning system monitor unit calculations for three intensity modulated radiotherapy delivery techniques
Background: We have validated the monitor unit calculations from a commercially available treatment planning system (TPS) for three intensity modulated radiotherapy (IMRT) planning techniques for tangential breast irradiation by using ionization chamber measurements. Materials and Methods: Treatment plans were generated for forty-two breast patients by a forward planned field in field ...
متن کاملIntensity modulated proton therapy.
Intensity modulated proton therapy (IMPT) implies the electromagnetic spatial control of well-circumscribed "pencil beams" of protons of variable energy and intensity. Proton pencil beams take advantage of the charged-particle Bragg peak-the characteristic peak of dose at the end of range-combined with the modulation of pencil beam variables to create target-local modulations in dose that achie...
