no. 1 approach

[0035] figure 1 It is a figure which shows the structure of the radiation therapy system 1 concerning 1st Embodiment. Such as figure 1 As shown, the radiation therapy system 1 has a CT device 2 for treatment planning, an MRI (magnetic resonance imaging) device 3 , a nuclear medicine diagnostic device 4 , an ultrasonic diagnostic device 5 , a treatment plan assisting device 6 , and a treatment planning device connected to each other via a network. 7 and radiation therapy device 8 .

[0036] The CT device 2 for treatment planning, the MRI device 3 , the nuclear medicine diagnostic device 4 , and the ultrasonic diagnostic device 5 are medical systems that generate medical images of patients.

[0037] The treatment planning CT apparatus 2 is an X-ray computed tomography apparatus for generating CT images used in treatment planning. The treatment planning CT apparatus 2 irradiates X-rays from the X-ray tube to the patient while rotating a rotating housing holding the X-ray tube ...

no. 2 approach

[0096] The treatment planning device 7 according to the second embodiment creates a radiation therapy plan based on the classification result information of each tumor region obtained by the treatment plan assisting device 6 . Next, a radiation therapy system 1 according to a second embodiment will be described. In addition, in the following description, the same code|symbol is attached|subjected to the component which has substantially the same function as 1st Embodiment, and it repeats description only when necessary.

[0097] As an example, the treatment planning device 7 according to the second embodiment acquires the patient's medical image ( Figure 5 The marked medical image shown), and the classification result information including the result of classifying the tumor area included in the medical image as the primary lesion or the metastatic lesion. The treatment planning device 7 creates a radiation treatment plan for the patient based on the acquired classification ...

no. 3 approach

[0126] In the first and second embodiments, the treatment plan assisting device 6 classifies primary lesions or metastatic lesions, and the treatment planning device 7 prepares a treatment plan. However, these processes can also be performed only by the treatment planning device 7 . Next, a radiation therapy system 1 according to a third embodiment will be described. In addition, in the following description, the same code|symbol is attached|subjected to the component which has substantially the same function as 1st and 2nd embodiment, and it repeats description only when necessary.

[0127] Figure 14 It is a diagram showing the configuration of the treatment planning device 7 included in the radiation therapy system 1 according to the third embodiment. Such as Figure 14 As shown, the treatment planning device 7 has a processing circuit 71B, a communication interface 72 , a display device 73 , an input interface 74 and a storage circuit 75 . The processing circuit 71B ha...

Abstract

Primary and metastatic lesions are distinguished in the treatment plan. A radiotherapy system according to an embodiment includes processing circuitry. The processing circuitry specifies at least onetumor area in a medical image of a patient, and outputs classification result information including a result of classifying this / these tumor area(s) as either a primary lesion or a metastatic lesion based on an image feature amount of this / these tumor area (s).

Description

[0001] The present invention is based on and claims priority to Japanese Patent Application No. 2019-110456 filed on June 13, 2019 and Japanese Patent Application No. 2020-85959 filed on May 15, 2020, and the original patent The entire content of the application is hereby incorporated by reference. technical field [0002] Embodiments disclosed in this specification and the like relate to a radiation therapy system, a treatment planning support method, and a treatment planning method. Background technique [0003] The lesion that gave rise to the tumor in the first place is called the primary lesion. For example, when a tumor is first formed in the stomach and the tumor cells migrate to the lungs along with blood and lymph flow, the primary focus of the tumor that has metastasized to the lungs is a gastric tumor. Because what is formed at the site of metastasis is not the cells of the lung tumor, but the cells of the stomach tumor. [0004] In the treatment planning of rad...
