  • Systems and methods for constructing images
    Patent number: 8135198
    Abstract: Techniques and systems for constructing a three-dimensional representations of anatomical structures from a series of images of the structure include creating interpolated images between actual images and defining voxels based on pixel values of the actual and interpolated images. A three-dimensional representation of the structure may be constructed based on the voxels.

  • Calibrating imaging devices
    Patent number: 8000442
    Abstract: 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.

  • Verifying lesion characteristics using beam shapes
    Patent number: 7729744
    Abstract: A patient's lesion is localized for the purpose of administering radiation treatment by obtaining a beam shape representation along one or more beam directions of a radiation treatment device. An image corresponding to the lesion is obtained from each beam direction, and the beam shape and image are fixed to a common coordinate system to facilitate alignment.

  • Weighted surface-to-surface mapping
    Patent number: 7672705
    Abstract: 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.

  • Radiotherapy treatment monitoring using ultrasound
    Patent number: 7662097
    Abstract: 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.

  • System and method for detecting drifts in calibrated tracking systems
    Patent number: 7535411
    Abstract: A method and system for detecting drift in calibrated tracking systems used to locate features with respect to one or more coordinate systems allows medical devices to be accurately tracked within a reference coordinate system, and facilitates detection and compensation for changes in the orientation of the tracking system with respect to the coordinate system over time.
