Parallel quantum annealing target point distribution calculation method

Abstract

The invention discloses a parallel quantum annealing target point distribution calculation method which comprises the steps of establishing a tumor target area and damaged organ data model through CT or MR data image analysis and doctor diagnosis; then, performing quick calculation of key point dosage distribution through a Gamma ray three-dimensional orientation rotating focusing radiotherapy machine beam characteristic, comparing the key point dosage distribution with a clinically required radiotherapy target, defining a target function according to a prescription dosage of the target area and the tolerable dosage of the damaged organ, setting a choice rule according to a simulated annealing algorithm, and performing new calculation comparison, and finally obtaining an anticipated result; and finally, performing accurate calculation on dosage distribution according to the parameter which corresponds with the calculated anticipated result, and obtaining final dosage distribution in the irradiation area. According to the parallel quantum annealing target point distribution calculation method, automatic machine calculation is utilized in a calculation process, thereby reducing subjective factors such as physicist experience, realizing no requirement for calculation process intervention by a plan designer, and realizing relatively objective calculation result. Furthermore, reversed plan designing realizes advantages of reducing subjective factors such as physicist experience, increasing plan designing speed, improving economic benefit and social benefit of radiotherapy, and realizing better satisfaction for a clinical requirement.

Description

technical field [0001] The invention belongs to the technical field of radiotherapy dose calculation, and relates to the calculation technology of the reverse radiotherapy plan of a gamma ray stereotactic rotary focusing radiotherapy machine. Background technique [0002] Gamma ray stereotaxic rotary focusing radiotherapy machine is a stereotactic radiosurgery treatment equipment that integrates stereotactic technology and radiosurgery technology. Concentrated radiation is irradiated on the pre-selected target area in the body, and destroys the tissue in the target point once and lethally, so as to achieve the therapeutic effect of surgical resection or damage. Stereotactic radiosurgery is essentially different from general surgery, and it avoids the traditional The risks of post-operative bleeding, infection, and possible damage to vital functional organs created by open surgical procedures create a non-invasive surgical approach. [0003] Such as figure 1 As shown, the g...

[0006] However, the design of the forward plan needs to consider multiple factors comprehensively, and relies on the experience of the physicist and the understanding of the treatment machine. The subjective factors are strong. The most important thing is that the design of each plan takes a long time and the cost of resources is relatively high.
