Embodiment Construction

[0126] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0127] Such as figure 1 , figure 2 , image 3 As shown, before the start of radiotherapy plan design, the patient's radiotherapy plan CT should be imported into the Pinnacle system, and the radiotherapy physician will outline the radiotherapy target area PTV of rectal cancer and the corresponding organs at risk, left and right femoral heads (named Lfemoralhead and Rfemoralhead), Bladder (named as Bladder) and small intestine (named as Smallintestine), given the clinical fractional treatment dose McGy and fractional number N, and the dosimetrist will remove and lock the bed on the CT image of the patient’s radiotherapy plan in the Pinnacle system according to the department’s conditions Operation, frame the CT image range that needs to be measured and calculated...

Abstract

The invention discloses a rectal cancer VMAT plan automatic generation method based on a Pinnacle plan system. The method comprises the steps of locating information inspection, auxiliary outline generation, plan central point generation, radiation field adding, dosage adding, plan optimization and the like. According to the method, under the circumstance that no manual intervention exists, designing of a rectal cancer VMAT plan is completed automatically, clinical requirements can be well satisfied, and the high quality radiotherapy plan can be obtained.

Description

technical field [0001] The invention relates to the medical field, in particular to a method for automatically generating a rectal cancer VMAT plan based on a Pinnacle planning system. Background technique [0002] At present, rectal cancer has become a common high-incidence species in clinical practice, and the demand for radiotherapy for rectal cancer is gradually increasing. Radiation therapy (Radiation Therapy) is one of the three effective means of treating tumors. Radiation therapy first needs to obtain the positioning CT of the patient and design a radiotherapy plan, and then import the radiotherapy plan into the accelerator system to treat the patient. Therefore, radiotherapy plan design is an important step in the radiotherapy process. Volumetric-Modulated Arc Therapy (VMAT) is a radiotherapy intensity-modulated technique developed in recent years. Compared with traditional static intensity-modulated techniques, the volumetric-modulated intensity-modulated techniqu...
