摘要： A displacement of a lesion within a patient is determined for the purpose of administering radiation treatment by generating sets of surface elements from three-dimensional images of the lesion taken at different times. Weights are assigned to the surface elements, and based on weights and the proximity of corresponding elements in one set to elements in another set, a displacement is determined.

摘要： Radiation beam parameters are determined by manipulating a tool about a patient in order to determine a desired beam entry point and/or beam angle. In certain embodiments, a visual representation of the beam may be displayed along with images of internal and external anatomical features of the patient, and used to determine couch and/or gantry manipulation parameters to move the patient into a desired position with respect to a treatment delivery device.

摘要： Methods and apparatus for calibrating images and imaging devices to common coordinate systems utilize, in some embodiments, rods that detectably reflect an acoustic signal regardless of the incidence angle of the signal with respect to the rods. Typically, the rods are disposed within a “phantom” at known positions with respect to a room coordinate system. Images of the cylindrical rods may be obtained from different directions, allowing the imaging device to be calibrated to the room coordinate system.

摘要： Methods and systems for assessing the effects of therapy on a patient include obtaining baseline and treatment ultrasound scans of a treatment area of a patient where the treatment ultrasound scans are taken subsequent to the baseline scan and at various times during a course of radiotherapy treatment sessions. The baseline and treatment ultrasounds are compared, and as a result a damage map representing cell death within the treatment area can be constructed.

摘要： Radiation treatment is delivered to a patient by positioning the patient such that a radiation beam is delivered to a lesion within the patient along a beam-delivery path while securing a diagnostic imaging device about the patient such that the diagnostic imaging device does not intersect the beam-delivery path. Radiation therapy is simultaneously delivered along the beam-delivery path while diagnostic images are obtained using the imaging device.

摘要： Various implementations of the invention provide techniques and supporting systems that facilitate real-time or near-real-time ultrasound tracking for the purpose of calculating changes in anatomical features during a medical procedure. More specifically, anatomical features within a patient undergoing a medical procedure are tracked by obtaining temporally-distinct three dimensional ultrasound images that include the feature of interest and obtaining a targeted subset of ultrasound images focused on the feature. Based on the targeted subset of ultrasound images, a displacement of the feature is determined and image parameters used to obtain the targeted subset of ultrasound images are adjusted based on the displacement. This results in a time-based sequence of three dimensional images and targeted ultrasound images of the feature that identify changes in the position, size, location, and/or shape of the feature.
