    摘要： Embodiments of the disclosure may be directed to a system for generating a motion target volume representative of shape changes of a target region in a patient. The system may comprise at least one computer system configured to receive a plurality of electronic medical images that include the target region, and each of the plurality of images may have been taken at a different time point. The computer system may be configured to define a three-dimensional volume containing the target region in each of the plurality of images, and the three-dimensional volume may be different in at least two of the plurality of images due to differences in shape of the target region in the at least two images. The computer system may also be configured to co-register the three-dimensional volumes and generate the motion target volume, wherein the motion target volume encompasses each of the three-dimensional volumes.

    摘要： The present invention discloses a homologous dual-energy accelerator and a therapy device comprising the homologous accelerator. The homologous dual-energy accelerator comprises an electron emitting device and an accelerating device, wherein the electron emitting device is located at the input end of the accelerating device, and electrons generated by the electron emitting device are emitted from the output end of the accelerating device after being accelerated by the accelerating device; the homologous dual-energy accelerator further comprises at least one separation deflection device which is arranged on the output end side of the accelerating device and used for changing the motion trail of partial electrons among the electrons accelerated by the accelerating device. The homologous dual-energy accelerator has the advantages that the inventor discovers that the speeds and energy of all electrons are not completely same after the electrons are accelerated by the accelerating device; the inventor uses the separation deflection device arranged on the output end side of the accelerating device through the discovery, the motion trail of partial electrons having relatively low energy level among the particles accelerated by the accelerating device is forcibly changed, the electrons having different energy levels in a homologous electron beam are separated, and two energy levels of electron beams are thus obtained, wherein the high-energy electron beam continues an original path and is used for radiotherapy, and the other path of low-energy electron beam is used for tracking lesions and detecting the therapeutic effect.
