Introduction

Berthold K P Horn is a notable inventor based in Intervale, NH (US). He has made significant contributions to the field of imaging technology, particularly in X-ray systems. With a total of 7 patents, his work has advanced the capabilities of phase contrast imaging.

Latest Patents

Horn's latest patents include a "Distributed, field emission-based X-ray source for phase contrast imaging." This invention discloses an X-ray source that utilizes a cathode array of individually controlled field-emission electron guns. The field emission guns feature very small diameter tips that produce a narrow beam of electrons. These beams are accelerated through an acceleration cavity and directed to a transmission type anode, creating a small spot size, typically less than five micrometers. The individually controllable electron guns can be selectively activated in patterns, enhancing the effectiveness of phase contrast imaging.

Another significant patent is the "Method for coded-source phase contrast X-ray imaging." This method describes a technique for performing phase contrast imaging using an array of independently controllable X-ray sources. The array can produce a distinct spatial pattern of X-ray radiation, allowing for the encoding of phase contrast signals without the need for a coded aperture. This innovation increases the flexibility of the imaging method and enhances the angular resolution compared to traditional coded-aperture imaging.
