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.
