Title: Innovations in Medical Imaging by Christopher H. Marshall

Introduction

Christopher H. Marshall is a notable inventor based in New York, NY (US), recognized for his contributions to the field of medical imaging. With a total of 2 patents, he has made significant advancements in computed tomography (CT) technology, enhancing the efficiency and safety of X-ray scanning procedures.

Latest Patents

Marshall's latest patents include a method and apparatus for computed tomography of portions of a body plane. This innovation focuses on a method and apparatus for computed axial tomography (CAT) image reconstruction applicable to X-ray scanning of the human body. The technology involves successive series of calculations that determine the values of a characteristic in defined segmented areas of an examination plane. By reducing the time and equipment requirements for reconstruction calculations, this method significantly improves the efficiency of imaging processes. Additionally, it allows for the calculation and display of images that represent the difference between the value of the characteristic at a reconstruction point and the average value in adjacent regions. This advancement leads to a reduction in radiation dose to patients and computation time in X-ray computerized axial tomography scanning systems. The differential displays can be adjusted to image boundaries, overcoming gray scale resolution problems typical of prior art displays. Furthermore, image artifacts attributable to interpolation errors can be minimized with negligible effect on resolution by incorporating a weighting function, preferably a Gaussian function, in the image reconstruction.
