Abstract

Patient motion during medical imaging can create significant degradation of images acquired in a clinical setting. Even breathing induced patient motion often leads to blurred imagery compromising its resolution and diagnostic utility. External motion tracking (EMT) technologies are one current method of tracking patient motion, but the current EMTs use radiation that is reflected off clothing or fixed markers, thus tracking only the patient’s garments. Researchers at U. Mass Worcester’s Chan Medical School and U. Mass Lowell’s Biomedical Terahertz Technology Center are seeking novel EMTs that use a part of the electromagnetic spectrum where clothing is transparent, designated as the millimeter wavelength region. For this purpose, the U. Mass. Team has developed a 75 GHz continuous-wave stepped frequency radar with 8 GHz bandwidth to investigate the system as a source-receiver tracking technology.
