An Overview of Potential Medical Applications of Microwave Kinetic Inductance Detectors

Abstract

Microwave kinetic inductance detectors (MKIDs) have proven to be a versatile detector technology and are very promising for several applications in medical imaging. Deep imaging into human tissues often requires detectors with low background noise, high detection efficiency, broad wavelength sensitivity or single-pixel energy resolution. MKIDs offer a unique combination of valuable features for medical imaging but have so far not been discussed much for modern medical instrumentation. This represents an exciting opportunity to investigate the potentially powerful advantages MKIDs could offer for clinical studies in several areas. The most promising fields for MKIDs in medical imaging include fluorescence microscopy, near-infrared spectroscopy, energy-resolved medical X-ray imaging and synchrotron X-ray microscopy. We present the respective advantages MKIDs offer for these fields and compare them to current detector state-of-the-art.
