An important recent development is the advent of new X-ray detectors, i.e., photon-counting detectors (PCD), which have been introduced in recent clinical prototype systems, called PCD computed tomography (PCD-CT) or photon-counting CT (PCCT) or spectral photon-counting CT (SPCCT) systems. PCD allows a pixel up to 200 microns pixels at iso-center, which is much smaller than that can be obtained with conventional energy integrating detectors (EID). PCDs have also a higher dose efficiency than EID mainly because of electronic noise suppression. In addition, the energy-resolving capabilities of these detectors allow generating spectral basis imaging, such as the mono-energetic images or the water\/iodine material images as well as the K-edge imaging of a contrast agent based on atoms of high atomic number. In recent years, studies have therefore been conducted to determine the potential of PCD-CT as an alternative to conventional CT for chest imaging.<\/jats:p>","DOI":"10.3390\/jcm10245757","type":"journal-article","created":{"date-parts":[[2021,12,9]],"date-time":"2021-12-09T21:46:58Z","timestamp":1639086418000},"page":"5757","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":92,"title":["Spectral Photon-Counting CT Technology in Chest Imaging"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0314-4010","authenticated-orcid":false,"given":"Salim Aymeric","family":"Si-Mohamed","sequence":"first","affiliation":[{"name":"INSA-Lyon, University of Lyon, University Claude-Bernard Lyon 1, UJM-Saint-\u00c9tienne, CNRS, Inserm, CREATIS UMR 5220, U1206, 69621 Lyon, France"},{"name":"Radiology Department, Hospices Civils de Lyon, 69500 Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jade","family":"Miailhes","sequence":"additional","affiliation":[{"name":"Radiology Department, Hospices Civils de Lyon, 69500 Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6199-0042","authenticated-orcid":false,"given":"Pierre-Antoine","family":"Rodesch","sequence":"additional","affiliation":[{"name":"INSA-Lyon, University of Lyon, University Claude-Bernard Lyon 1, UJM-Saint-\u00c9tienne, CNRS, Inserm, CREATIS UMR 5220, U1206, 69621 Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sara","family":"Boccalini","sequence":"additional","affiliation":[{"name":"INSA-Lyon, University of Lyon, University Claude-Bernard Lyon 1, UJM-Saint-\u00c9tienne, CNRS, Inserm, CREATIS UMR 5220, U1206, 69621 Lyon, France"},{"name":"Radiology Department, Hospices Civils de Lyon, 69500 Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hugo","family":"Lacombe","sequence":"additional","affiliation":[{"name":"INSA-Lyon, University of Lyon, University Claude-Bernard Lyon 1, UJM-Saint-\u00c9tienne, CNRS, Inserm, CREATIS UMR 5220, U1206, 69621 Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Val\u00e9rie","family":"Leitman","sequence":"additional","affiliation":[{"name":"INSA-Lyon, University of Lyon, University Claude-Bernard Lyon 1, UJM-Saint-\u00c9tienne, CNRS, Inserm, CREATIS UMR 5220, U1206, 69621 Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5591-0955","authenticated-orcid":false,"given":"Vincent","family":"Cottin","sequence":"additional","affiliation":[{"name":"National Reference Center for Rare Pulmonary Diseases, Louis Pradel Hospital, Hospices Civils de Lyon, UMR 754, INRAE, Claude Bernard University Lyon 1, Member of ERN-LUNG, 69677 Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Loic","family":"Boussel","sequence":"additional","affiliation":[{"name":"INSA-Lyon, University of Lyon, University Claude-Bernard Lyon 1, UJM-Saint-\u00c9tienne, CNRS, Inserm, CREATIS UMR 5220, U1206, 69621 Lyon, France"},{"name":"Radiology Department, Hospices Civils de Lyon, 69500 Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5096-4698","authenticated-orcid":false,"given":"Philippe","family":"Douek","sequence":"additional","affiliation":[{"name":"INSA-Lyon, University of Lyon, University Claude-Bernard Lyon 1, UJM-Saint-\u00c9tienne, CNRS, Inserm, CREATIS UMR 5220, U1206, 69621 Lyon, France"},{"name":"Radiology Department, Hospices Civils de Lyon, 69500 Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"27","DOI":"10.1016\/j.nima.2017.04.014","article-title":"Review of an initial experience with an experimental spectral photon-counting computed tomography system","volume":"873","author":"Sigovan","year":"2017","journal-title":"Nucl.
