摘要： A method and system is disclosed for analyzing image data of a subject. The image data can be collected with an imaging system in a selected manner and/or motion. The image data may include selected overlap and be acquired with an imaging system that generates a plurality of perspectives for more than one location. An automatic system and method may then define or identify various features and/or allow for registration for alternative image data.

摘要： A method and system is disclosed for analyzing and evaluating image data of a subject. The image data can be collected with an imaging system in a selected manner and/or motion. More than one projection may be combined to generate and create a selected view of the subject. The evaluation may be a location determination of a member positioned within the subject.

摘要： Selected artifacts, which may be based on distortions or selected attenuation features, may be reduced or removed from a reconstructed image. Various artifacts may occur due to the presence of a metal object in a field of view. The metal object may be identified and removed from a data that is used to generate a reconstruction.

摘要： A device receives a prior image associated with an anatomy of interest, and receives measurements associated with the anatomy of interest. The device processes the prior image and the measurements, with a reconstruction of difference technique, to generate a difference image associated with the anatomy of interest, wherein the difference image indicates one or more differences between the prior image and the measurements. The device generates, based on the difference image and the prior image, a final image associated with the anatomy of interest, and provides, for display, the final image associated with the anatomy of interest.

摘要： Embodiments provide a modular phantom that enables quantitative assessment of imaging performance (e.g., spatial resolution, image uniformity, image noise, contrast to noise ratio, cone-beam artifact) and dosimetry in cone-beam computed tomography (CT). The modular phantom includes one or more modules for various imaging performance tests that may be rearranged in the phantom to accommodate the design of various cone-beam CT imaging systems. The modular phantom includes one or more of a cone-beam module, an angled edge module, or a line spread module. The phantom may be inserted into a larger sleeve and be used to assess imaging performance and dosimetry in whole body CT imaging systems.

摘要： An integrated computed tomography (CT) treatment couch system may include a base platform configured to couple to a rotatable floor component associated with a medical accelerator, a pedestal component mounted to the base platform, a treatment couchtop disposed on the pedestal component, and a CT scanner device. The CT scanner device may include a support structure and a CT gantry. The support structure may be mounted to the base platform or to the pedestal component. The CT gantry may have a bore and may be oriented such that the bore is in line with the treatment couchtop. The CT gantry may be configured to generate on-line helical CT scans to guide radiotherapy provided by the medical accelerator.

摘要： A device may receive a set of perioperative images including a set of pre-operative images depicting one or more anatomical structures of a surgical candidate. The set of pre-operative images may be processed using image analysis techniques to determine a first set of quantitative measures related to the anatomical structure(s) of the surgical candidate. The device may use a data model that has been trained based on perioperative data associated with a patient cohort sharing clinical characteristics with the surgical candidate to predict outcomes from one or more therapeutic options for the surgical candidate based on the first set of quantitative measures and a second set of quantitative measures related to a profile associated with the surgical candidate. Based on the predicted outcomes, the device may provide, to a client device, a recommendation relating to the therapeutic options for the surgical candidate and information to support the recommendation.
