Summary of the 7th Workshop on Medical Applications of Spectroscopic X-ray detectors

About

The seminar will take place in "hybrid format" with the speaker present in person

This seminar will report on the latest developments presented during the 7th Workshop on Medical Applications of Spectroscopic X-ray detectors. The Workshop is held every 2 years and unites researchers from hospitals, industry, academia and research organizations. The presentation will summarize key results, themes, and messages from the workshop and is intended for interested individuals in science, medicine or the general public. Within clinical radiology spectral x-ray imaging has now entered routine clinical practice. This improvement in patient care has arisen from the development of photon counting. This method of measuring individual x-ray photons has enabled higher spatial resolution, lower x-ray dose, and multi-energy imaging. The technology has its roots in the 1980s and 1990s when the High Energy Physics community centered around CERN developed a combination of segmented silicon sensors and very large-scale integration (VLSI) readout circuits to enable precision measurements at unprecedented event rates. By the late 1990's, several groups had proofs of concept and by 2008, pre-clinical spectral photon counting CT systems were under investigation by several groups. In 2011, leaders in the field decided to bring together engineers, physicists, and clinicians to help to address the scientific, medical and engineering challenges associated with guiding the technology towards clinical adoption. 13 years later the first scanners equipped with spectroscopic X-ray detectors have obtained FDA approval for clinical use and a large quantity of pre-clinical data suggests a huge potential for high quality morphological and perhaps functional imaging. However, many technical and medical challenges remain and the need for this highly specialized workshop remains.
