Title: Walter Hillen: Innovator in X-ray Imaging Technology
Introduction
Walter Hillen is a prominent inventor based in Aachen, Germany. He has made significant contributions to the field of X-ray imaging technology, holding a total of 12 patents. His work focuses on enhancing the quality and accuracy of X-ray images through innovative devices and methods.
Latest Patents
Hillen's latest patents include a "Device for scanning an X-ray image." This device utilizes a previously locally uniformly charged photoconductor that is discharged based on local intensity. It employs several electrometer probes arranged in a row to scan the charge pattern of the photoconductor, which is successively displaced in the scanning direction. The probes provide image values corresponding to discharges at relevant pixels. To eliminate streaky artifacts, the image values are processed through an analog-to-digital converter and stored in an image memory. A signal processor applies low-pass and high-pass filter functions to neighboring pixels to enhance image quality.
Another notable patent is the "Method of generating X-ray images and device suitable for carrying out." This invention involves a photoconductor on a conductive substrate, where the surface potential can be read by probes. To avoid image artifacts caused by varying sensitivities of the probes, the substrate potential is varied during a test phase. This generates test data that forms correction data, which is stored to correct image data from subsequent X-ray exposures.
Career Highlights
Walter Hillen is currently associated with U.S. Philips Corporation, where he continues to innovate in the field of imaging technology. His work has significantly impacted the medical imaging industry, improving diagnostic capabilities and patient outcomes.
