Title: Marcel Van Herk: Innovator in Medical Imaging Technology

Introduction

Marcel Van Herk is a prominent inventor based in Amsterdam, Netherlands. He has made significant contributions to the field of medical imaging, particularly in the area of computed tomography (CT) scanning. With a total of 6 patents to his name, Van Herk's work has advanced the capabilities of imaging technologies, enhancing patient care and treatment outcomes.

Latest Patents

One of Van Herk's latest patents focuses on motion artefact reduction in CT scanning. This invention addresses the challenges posed by sporadic motion, such as gas pockets moving around the rectum, which can complicate imaging. The technology allows for the automatic detection of such movements by enhancing low-density features around the prostate in individual X-ray images. By projecting these features on the cranio-caudal axis, the invention forms a one-dimensional image and combines successive projections to create a two-dimensional image. This process identifies angular ranges that need to be discarded, improving the accuracy of CT scans.

Another notable patent involves methods and systems for protecting critical structures during radiation treatment. This innovation provides a framework for safeguarding critical structures while administering radiation to patients. A register receives proposed positions for radiation beams concerning a critical structure, and a processor predicts the cumulative dose volume based on the dose distribution. If the cumulative dose exceeds a tolerance value, the dose distribution can be adjusted to ensure patient safety.
