Title: Innovations of Robert Speller in X-ray Imaging

Introduction

Robert Speller is a notable inventor based in Bedfordshire, GB, recognized for his contributions to the field of X-ray imaging. With a total of six patents to his name, he has made significant advancements that enhance the capabilities of X-ray apparatus.

Latest Patents

One of his latest patents focuses on a method of aligning masks for phase imaging or phase contrast imaging in X-ray apparatus. This method utilizes a pixel-type X-ray detector and addresses the non-idealities of real detectors. The process involves moving the mask into various translational position increments to identify the increment that yields maximum or minimum intensity. The alignment positions are selected to minimize steps in a plot of the increment over the detector area.

Another innovative patent by Speller involves a method of phase imaging that employs X-ray beams with edges overlapping the pixels. This technique allows for the generation of a phase image from two separate images, each measured with different edges of the X-ray beam. By calculating the gradient of the X-ray absorption function and incorporating a proportional term in the image processing, a quantitative phase image can be produced.
