Multi-chamber beam request sorting algorithm for proton therapy

Abstract

The invention discloses a proton treatment multi-chamber beam request sorting algorithm. The algorithm comprises the following steps: S1, firstly, determining a treatment time sequence and a calculation algorithm of a proton pencil beam scanning technology; on the basis of a time sequence and an irradiation field angle of a proton pencil beam scanning time request of each treatment room, a result of proton radiation Monte Carlo radiation dose simulation calculation and an actually measured dose is combined; s2, calculating beam irradiation time; s3, estimating the external irradiation personal dose of the proton treatment system; s4, performing proton beam request sorting algorithm logic; s5, after the treatment room is prepared, the beam is requested; s6, a technician enters a treatment room; s7, the overall beam requests the technician, and the technician executes the beam request; s8, judging the state of each treatment room, redistributing beams, and optimizing the waiting time of each treatment room, the proton treatment multi-room beam request sorting algorithm is provided, the unnecessary penetrating radiation body dosage of proton technicians is effectively reduced, the waiting time of each treatment room is optimally selected, and the treatment efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of proton therapy, and in particular relates to a multi-chamber beam request sorting algorithm for proton therapy. Background technique [0002] Proton therapy is the current method of precision radiation therapy for cancer. Based on the unique Bragg peak dose distribution characteristics of the proton beam, the Bragg peak dose control at different depths can be achieved by adjusting the proton beam energy, so as to achieve precise radiation therapy. Cyclotrons are widely used in proton therapy, and the proton beams they produce have the advantages of continuous and stable. At present, a large number of proton centers are being built in China, among which multi-chamber therapy systems account for a large share. [0003] Since the multi-chamber therapy system shares a proton accelerator, each therapy room needs to share the beam in turn. The multi-chamber therapy system in the prior art may have a certain am...

Problems solved by technology

[0003] Since the multi-room treatment system shares a proton accelerator, each treatment room needs to share the beam in turn. In the multi-room treatment system in the prior art, there may be a certain amount of radiation that penetrates the shielding body due to the proton beam, which will cause damage to the technician during use. Unnecessary radiation is caused, and the waiting time of patients in multiple treatment rooms cannot be optimized at the same time, resulting in the problem of low treatment efficiency for patients. For this reason, we propose a proton therapy multi-room beam request sorting algorithm
