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： A positioning apparatus automatically performs a patient positioning calculation at high speed and a positioning method. A positioning apparatus 40 has, as functional components, a DRR image generation element 41 that generates the DRR image based on the CT image data, an optimization element 43 that calculates the positional gap of the patient 57 by optimizing the fluoroscopic projection parameters; and an initial parameter adjustment element 42 that changes the initial position of the fluoroscopic projection parameters prior to optimization of fluoroscopic projection parameters with regard to the rotatable and translation of the CT image data relative to the optimization element 43.

摘要： A method and apparatus for manipulation of a respiratory model via adjustment of parameters associated with model images is described. A subset of the images that are used with the model that is associated with the position and motion of a targeted region of the patient to receive radiation treatment may be identified. The subset of images may be sorted. A graphical user interface (GUI) that identifies two or more of the images of the sorted subset may be provided. A selection associated with one of the images of the sorted subset may be received by the GUI. Furthermore, a new model to identify the targeted region based on the selection that is associated with one of the two or more images may be generated.

摘要： An adaptive therapy delivery system can receive imaging information including a volumetric image comprising a target such as a tumor or one or more other structures, and can receive imaging information corresponding to one or more imaging slices comprising different portions of the target, such as imaging slices acquired at different times after acquisition of the volumetric image. The system can spatially register information from an earlier-acquired image with a portion of the target included in a later-acquired one of the imaging slices. The system can then determine an updated location of the target indicated by the spatially-registered information. Using the updated location, the system can generate an updated therapy protocol to control delivery of a therapy beam.

摘要： The invention comprises a method and apparatus for slowing positively charged particles, comprising the steps of: (1) transporting the positively charged particles from an accelerator, along a beam transport line, and into a nozzle system; (2) placing a first liquid in a first chamber in a beam path of the positively charged particles; (3) placing a second liquid in a second chamber in the beam path of the positively charged particles; (4) moving the first and second chamber with the nozzle system; (5) slowing the positively charged particles using the first liquid and the second liquid; (6) moving the first chamber in a first direction to yield a longer first pathlength of the positively charged particles through the first chamber; and (7) moving the second chamber opposite the first direction to yield a longer second pathlength of the positively charged particles through the second chamber.

摘要： Systems and methods are provided for target tracking using a quality indicator during radiation therapy treatment. An exemplary method may include determining a localization result indicating a location of a target in a plurality of images representative of images acquired in a radiation therapy treatment session. The method may also include determining a quality indicator for each localization result. The method may further include extracting one or more features from each localization result. In addition, the method may include training the classifier using the localization result and one or more of the extracted features.

摘要： A medical image processing apparatus of an embodiment has acquisitor, a first landmark detector, and an estimator. The acquisitor acquires a perspective image of an object to be treated imaged by an imaging apparatus. The first landmark detector detects a position of a landmark that appears in the perspective image acquired by the acquisitor. The estimator, based on relationship information indicating a relationship between the position of landmark and the position of a target, estimates the position of the search-for location of the object to be treated from the position of the landmark detected by the first landmark detector.
