Latest Patents
One of Sandrik's latest patents is titled "Method and apparatus for tomosynthesis image quality control." This invention provides a method and apparatus for ensuring the quality of images produced by tomosynthesis imaging systems. The process involves positioning a phantom with a predetermined sharpness at a specific angle relative to the imaging plane of an x-ray detector. It includes performing tomosynthesis acquisition to generate slice images using three-dimensional reconstruction algorithms. The method further entails selecting a slice image for measurement, identifying the sharpest edge in that image, and calculating the in-plane resolution and slice thickness using a modulation transfer function (MTF) algorithm.
Another significant patent is focused on "Systems, methods and apparatus for determining deviation of an x-ray field, a light field and a primary receptor." This invention involves positioning an electronic sensor in the projection field of an x-ray source to measure the deviation between the visible light field and the x-ray field. The system is designed to scale the deviation based on the sensor's position between the x-ray receptor and the x-ray source.
