Abstract
A radiation therapy system may be provided. The system may include a therapeutic apparatus. The therapeutic apparatus may include a radiation source for directing therapeutic radiation to at least one portion of a region of interest (ROI) of a subject, and an immobilizing device for immobilizing the subject. The system may obtain characteristics information of the subject. The system may preheat the immobilizing device according to a predictive model that processes the characteristics information of the subject. The system may send a control signal to the therapeutic apparatus for applying the therapeutic radiation to the at least one portion of the ROI immobilized by the preheated immobilizing device when the immobilizing device is preheated to a certain temperature.
Claims18
A radiation therapy system comprising:
- a therapeutic apparatus, wherein the therapeutic apparatus includes a radiation source for directing therapeutic radiation to at least one portion of a region of interest (ROI) of one of multiple subjects, immobilizing devices one of which is used for immobilizing the subject after being molded around the subject to form a molded immobilizing device;
- at least one storage device storing executable instructions;
- and
- at least one processing device in communication with the therapeutic apparatus and the at least one storage device, when executing the executable instructions, the at least one processing device causing the radiation therapy system to:
- obtain a radiation therapy planning protocol of the subject;
- obtain a preheated immobilizing device by preheating the molded immobilizing device by a preheating system before the immobilizing device for immobilizing the subject is installed in the therapeutic apparatus in response to a request for heating the molded immobilizing device, wherein the molded immobilizing device keeps a shape molded during the preheating and the radiation therapy treatment of the subject;
- wherein the preheated immobilizing device used for immobilizing the subject is mounted on a supporting platform of a treatment table of the therapeutic apparatus before a subject's turn for receiving the radiation therapy treatment;
- and
- control the therapeutic apparatus to apply the therapeutic radiation to the at least one portion of the ROI according to the radiation therapy planning protocol.
A therapeutic apparatus comprising:
- an imaging device configured to acquire image data with respect to a region of interest (ROI) of a subject;
- a radiation therapy device configured to apply therapeutic radiation to at least one portion of the ROI in response to a control signal, wherein the control signal is generated according to the acquired image data;
- and
- immobilizing devices one of which is configured to immobilize the subject after being molded around the subject to form a molded immobilizing-device, wherein the molded immobilizing device is preheated to a certain temperature to be a preheated immobilizing device before the therapeutic radiation by a preheating system before the immobilizing devices are installed in the therapeutic apparatus in response to a request for heating the molded immobilizing device, the preheated immobilizing device is mounted on a supporting platform of a treatment table of the therapeutic apparatus before a subject's turn for receiving the radiation therapy treatment, and the molded immobilizing device keeps a shape molded during the preheating and the radiation therapy treatment of the subject.
