However, even MRI imaging is dependent on the familiarity of the radiologist with the normal appearance of the TMJ; therefore, new approaches are needed. Our purpose here is to improve imaging quality of cone beam computed tomography (CBCT) as a tool to help in the diagnosis of JIA in the TMJ. We have designed and applied a filter (the Stacking Enhancement Filter) over a stock of CBCT images from the TMJs of two patients with JIA. We then made a visual comparison of the results with archival images from MRI of the same patients, to show that the filter substantially improves the visual quality of the image. The work on the image contrast and the increase of the difference of appearance between tissues of different densities (all the anatomical structures that are present within the joint) leads to an improvement of the resulting images of the TMJ without the use of a chemical contrast agent. We conclude that CBCT could be used as a filter tool for the analysis of the TMJs affected by arthritis. Our image processing technique yields images that possible improve the range of use of CBCT.<\/jats:p>","DOI":"10.1177\/20584601221074565","type":"journal-article","created":{"date-parts":[[2022,2,18]],"date-time":"2022-02-18T01:36:20Z","timestamp":1645148180000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["TMJ contrast enhancement in CBCT images using a new algorithm"],"prefix":"10.1177","volume":"11","author":[{"given":"Mar\u00eda Florinda","family":"Otero","sequence":"first","affiliation":[{"name":"Health Research Institute of Santiago de Compostela (IDIS), Santiago de Compostela, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pablo Garc\u00eda","family":"Tahoces","sequence":"additional","affiliation":[{"name":"Departamento de Electr\u00f3nica y Computaci\u00f3n, Universidade de Santiago de Compostela, Santiago de Compostela, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio","family":"Mera","sequence":"additional","affiliation":[{"name":"Rheumatology Service, Hospital Cl\u00ednico Universitario, Santiago de Compostela, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6024-6294","authenticated-orcid":false,"given":"Jorge","family":"Mira","sequence":"additional","affiliation":[{"name":"Health Research Institute of Santiago de Compostela (IDIS), Santiago de Compostela, Spain"},{"name":"Departamento de F\u00edsica Aplicada, Universidade de Santiago de Compostela, Santiago de Compostela, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2022,2,17]]},"reference":[{"key":"bibr1-20584601221074565","doi-asserted-by":"publisher","DOI":"10.1093\/ejo\/cjy066"},{"key":"bibr2-20584601221074565","unstructured":"European Commission.
