Latest Patents

One of Roggen's latest patents is titled "Dual domain tracking of target structures." This invention provides a method for determining a probability distribution of a three-dimensional point in a template feature map that matches a three-dimensional point in space. The system he developed receives projection data in one or two dimensions along with a three-dimensional simulation image. It extracts a template feature map from the simulation image using segmentation and transforms features from the projection data into three-dimensional space. The system then generates a three-dimensional feature map and compares it to the template feature map to determine an instantaneous probability distribution.

Another significant patent is "Beam-off motion thresholds in radiation therapy based on breath-hold level determination." This computer-implemented method involves determining the current position of a target volume of patient anatomy and computing an accumulated dose for non-target tissue near the target volume. If the accumulated dose is less than the current value for a dose budget, the system applies a treatment beam to the target volume while it is in the current position.
