Title: Innovations by Joseph J Grass
Introduction
Joseph J Grass is a notable inventor based in Brookfield, WI (US). He has made significant contributions to the field of X-ray technology, holding a total of 5 patents. His work focuses on enhancing the safety and effectiveness of X-ray imaging systems.
Latest Patents
One of his latest patents is for an "Automatic X-ray entrance dose compensation" system. This invention allows for the X-ray tube to be movable between a minimum and maximum distance from an image receptor. It generates signals that represent the X-ray tube focal spot-to-image distance (SID), the peak kilovoltage (kVp) to be applied during fluorographic exposure, and the desired brightness of the X-ray image. The processed signals develop a control signal that adjusts the X-ray tube filament current, ensuring a constant limited X-ray dose rate at the entrance plane of a patient, regardless of the selected kVp and SID settings.
Another significant patent is the "Device for aligning cooperating X-ray systems." This invention ensures that the isocenters of two independent frontal and lateral viewing X-ray systems are made coincident. It utilizes an X-ray permeable target frame with congruent crosshairs defined by X-ray impermeable lines. A small steel ball is positioned within the frame, allowing for precise alignment of the X-ray systems.
