A hybrid image based on different tissue specimen images is generated to compensate for blood and other fluids that interfere with imaging. Specimen is deposited into tray with fluid. X-ray and camera imaging devices acquire images of specimen and fluid. X-ray and optical images are processed for generation of hybrid image. Transparency modifications allow for multiple and different images to contribute to depiction of specimen edges or boundaries that would otherwise appear less clear in x-ray image due to interfering fluid. Transparency modifications in hybrid image also provide for sufficiently high transparency in certain optical image portions that would otherwise be opaque so that objects of interest depicted in x-ray image but not optical image are visible.

Appl.No PCT/CN2018/123964 Applicant OUR UNITED CORPORATION. Inventor LI, Jinsheng
Provided are a positioning method and apparatus, and a radiotherapy system, wherein same relate to the technical field of radiotherapy. According to the method, second coordinates of a treatment table when a target point of an affected part coincides with a device isocenter at a Gamma angle for treatment are calculated according to first coordinates of the treatment table acquired when a pre-set X-ray taking point coincides with an imaging point, first relative positions of the target point and the imaging point and second relative positions of the imaging point and the device isocenter, and the position of the treatment table is adjusted according to the second coordinates. Therefore, after the Gamma angle is adjusted during radiotherapy, the second coordinates of the treatment table when the target point coincides with the device isocenter at the adjusted Gamma angle can be accurately calculated, such that the precision of alignment of the target point and the device isocenter at different Gamma angles can be improved, in turn improving the precision of the radiotherapy.
