Latest Patents

One of Schreiber's latest patents is titled "Automatic material discrimination by using computer tomography." This invention provides a method and apparatus for combining information obtained from CT and Coherent Scatter Computed Tomography. It aims to better determine whether there are dangerous materials in baggage. The invention utilizes the attenuation coefficient and the diffraction pattern of the baggage to decide if it should be cleared.

Another significant patent is "Analysis of radiographic images." This patent discloses two analysis methods for a portal image. The first method checks the apparatus setup, while the second focuses on patient positioning. The first method involves preparing a reference radiation field image and a sample radiation field image. It includes defining a threshold value, setting pixels to a dark or bright state, and inspecting the difference image to ascertain changes in the radiation field. The second method filters the sample image, selects a region of interest, and determines the relative displacements of the reference and sample images.
