摘要： An image-guided radiosurgery method and system are presented that use 2D/3D image registration to keep the radiosurgical beams properly focused onto a treatment target. A pre-treatment 3D scan of the target is generated at or near treatment planning time. A set of 2D DRRs are generated, based on the pretreatment 3D scan. At least one 2D x-ray image of the target is generated in near real time during treatment. The DRRs are registered with the x-ray images, by computing a set of 3D transformation parameters that represent the change in target position between the 3D scan and the x-ray images. The relative position of the radiosurgical beams and the target is continuously adjusted in near real time in accordance with the 3D transformation parameters. A hierarchical and iterative 2D/3D registration algorithm is used, in which the transformation parameters that are in-plane with respect to the image plane of the x-ray images are computed separately from the out-of-plane transformation parameters.

摘要： A system and method for selecting follicular units for hair harvesting using imaging and processing techniques are provided. The method of selecting an order of harvesting follicular units is based on a combination of one or more policies and/or filters that are generally designed to improve a speed, quality and efficacy of the harvesting process. The method of the present invention may be implemented with various hair harvesting and transplantation systems, including manual, partially automated and fully automated systems.

摘要： An image-guided radiosurgery method and system are presented that use 2D/3D image registration to keep the radiosurgical beams properly focused onto a treatment target. A pre-treatment 3D scan of the target is generated at or near treatment planning time (CT DATA). A set of 2D DRRs are generated (DDR GENERATION A and DDR GENERATION B), based on the pretreatment 3D scan (CT DATA). At least one 2D x-ray image of the target is generated in near real time during treatment (X-RAY IMAGE A). The DRRs are registered with the x-ray images, by computing a set of 3D transformation parameters that represent the change in target position between the 3D scan and the x-ray images (IMAGE REGISTRATION). The relative position of the radiosurgical beams and the target is continuously adjusted in near real time in accordance with the 3D transformation parameters (GEOMETRIC TRANSFORMATION). A hierarchical and iterative 2D/3D registration algorithm is used, in which the transformation parameters that are in-plane with respect to the image plane of the x-ray images are computed separately from the out-of-plane transformation parameters.
