Radiology informatics firm Guardian Technologies International of Herndon, VA, has filed for a new patent covering an aspect of the company's Signature Mapping computer-aided detection (CAD) algorithm.
The patent filing is in addition to the 11 patents Guardian has already received, and covers technology that would enable the company's algorithm to detect suspicious tissue smaller than what a radiologist can see with the naked eye, according to the company.
The new patent enables Signature Mapping to visualize anatomical structures by analyzing the inherent difference in energy absorption of organs, tissues, or other types of material. The inherent differences in energy within each tissue or object form pixel and texture patterns in images that correspond to their physical properties, and Signature Mapping translates these patterns into unique "signatures" for each tissue or object, according to the company.
Guardian says Signature Mapping can be used across a wide variety of applications, including brain, lung, heart, prostate, and breast tissue, and across different modalities, such as CT, MRI, and x-ray.
