Title: Avilash Cramer and His X-Ray Imaging Innovations.

Introduction

Avilash Cramer is an inventor based in Cambridge, Massachusetts. His work includes X-ray imaging technologies designed to improve diagnostic information and make tomographic imaging more efficient. He is named on 2 patents.

Latest Patents

Cramer’s patent, “System and method for X-ray elastography using dynamic pulsing,” describes an imaging approach that combines conventional X-ray absorption images with information about the mechanical properties of tissue. Because breast cancers and surrounding healthy tissue can have similar X-ray absorption, this method aims to support more accurate diagnosis. It uses a vibration source to generate shear waves in a sample and synchronizes those waves with pulses from a cold-cathode X-ray source. The resulting stroboscopic images can be used to create stiffness maps alongside conventional X-ray images.

His patent, “Tomographic imaging system,” describes a non-rotating system with multiple X-ray sources housed in a vacuum manifold. The sources use non-thermionic cathodes, enabling rapid switching and potentially reducing scan time, motion artifacts, or radiation dose through under-sampled acquisition. The modular sources can be interconnected in a distributed ring or arranged in other imaging geometries, with modularity also intended to simplify system maintenance and repair.

Career Highlights

Cramer’s listed organizational affiliations include the United States of America as Represented by the Administrator of NASA and The General Hospital Corporation. His patent work spans medical imaging and tomographic system design.
