COMBINED RADIOTHERAPY ULTRASOUND DEVICE
First Claim
1. A system for irradiating a target volume with a radiation or particle beam, the system comprising:
- a radiotherapy device operable to irradiate the target volume with the radiation or particle beam;
an ultrasound device comprising an ultrasound transducer, the ultrasound device being operable to generate ultrasound data representing at least part of the target volume, the ultrasound transducer being positioned adjacent to the target volume;
a memory configured to store a treatment plan for irradiating the target volume with the radiation or particle beam; and
a processor operatively connected to the radiotherapy device, the ultrasound transducer, and the memory, the processor being configured to;
generate image data corresponding to the at least part of the target volume based on the generated ultrasound data; and
control the radiotherapy device based on the generated image data and the stored treatment plan.

Abstract
In order to minimize radiation directed to a region outside of a target volume of a patient during a radiation therapy and minimize the cost of an image-guided particle therapy system, the particle therapy system includes an ultrasound device having at least one ultrasound transducer positioned abutting or adjacent to an external surface of the patient. The ultrasound device and thus the ultrasound transducer are positioned outside of a beam path of a particle beam between a radiotherapy device generating the particle beam, and the target volume. The ultrasound device is operable to generate data representing the target volume and/or a region outside of the target region while the radiotherapy device directs the particle beam to the target volume. The particle therapy system includes a processor operable to control the radiotherapy device based on a comparison between the generated data representing the target volume and a predetermined treatment plan.
