An Overview of Potential Medical Applications of Microwave Kinetic Inductance Detectors

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.

Automation of MKID Simulations for Array Building with AEM (Automated Electromagnetic MKID Simulations)

Microwave Kinetic Inductance Detectors (MKIDs) are photon detectors comprised of superconducting LC resonators with unique resonant frequencies corresponding to their geometrical structure. As each pixel has its own geometry, electromagnetic simulations by hand of every pixel in a kilo-pixel array are impractical. Simulating fewer pixels and interpolating in between risks reduced pixel yield in arrays due to overlapping resonant frequencies. We introduce a new software called AEM (Automated Electromagnetic MKID simulations) that automates the constructions and simulations of every simulated MKID pixel in an array according to specified resonant frequencies and a Qc range. We show automated designs to have an increased pixel yield (avoiding loses due to interpolation completely), increased accuracy in resonance frequency and Qc values when compared to interpolated structures. We also demonstrate a simulated trial of AEM for 100 MKIDs between 4 & 8 GHz to produce MKIDs with accuracies of +-0.2 MHz with a runtime of 10 hrs 45 mins.
