This study assesses the CBCT image quality metrics using the criteria routinely used for diagnostic CT scanner accreditation as a first step towards the future use of HyperSight CBCT images for treatment planning and target\/organ delineations. Image performance was evaluated using American College of Radiology (ACR) Program accreditation phantom tests for diagnostic computed tomography systems (CTs) and compared HyperSight images with a standard treatment planning diagnostic CT scanner (Siemens SOMATOM Edge) and with existing CBCT systems (Varian TrueBeam version 2.7 and Varian Halcyon version 2.0).\u202f\u00a0Image quality performance for all Varian HyperSight CBCT vendor\u2010provided imaging protocols were assessed using ACR head and body ring CT phantoms, then compared to existing imaging modalities. Image quality analysis metrics included contrast\u2010to\u2010noise (CNR), spatial resolution, Hounsfield number (HU) accuracy, image scaling, and uniformity. All image quality assessments were made following the recommendations and passing criteria provided by the ACR. The Varian HyperSight CBCT imaging system demonstrated excellent image quality, with the majority of vendor\u2010provided imaging protocols capable of passing all ACR CT accreditation standards. Nearly all (8\/11) vendor\u2010provided protocols passed ACR criteria using the ACR head phantom, with the Abdomen Large, Pelvis Large, and H&amp;N vendor\u2010provided protocols produced HU uniformity values slightly exceeding passing criteria but remained within the allowable minor deviation levels (5\u20137 HU maximum differences). Compared to other existing CT and CBCT imaging modalities, both HyperSight Head and Pelvis imaging protocols matched the performance of the SOMATOM CT scanner, and both the HyperSight and SOMATOM CT substantially surpassed the performance of the Halcyon 2.0 and TrueBeam version 2.7 systems. Varian HyperSight CBCT imaging system could pass almost all tests for all vendor\u2010provided protocols using ACR accreditation criteria, with image quality similar to those produced by diagnostic CT scanners and significantly better than existing linac\u2010based CBCT imaging systems.<\/jats:p>","DOI":"10.1002\/acm2.14299","type":"journal-article","created":{"date-parts":[[2024,3,23]],"date-time":"2024-03-23T02:12:55Z","timestamp":1711159975000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["ACR benchmark testing of a novel high\u2010speed ring\u2010gantry linac kV\u2010CBCT system"],"prefix":"10.1002","volume":"25","author":[{"given":"Allison","family":"Haertter","sequence":"first","affiliation":[{"name":"Department of Radiation Oncology University of Pennsylvania  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Salerno","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Pennsylvania  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brandon","family":"Koger","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Pennsylvania  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"Kennedy","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Pennsylvania  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle","family":"Alonso\u2010Basanta","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Pennsylvania  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Dong","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Pennsylvania  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Boon\u2010Keng","family":"Teo","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Pennsylvania  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taoran","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Pennsylvania  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,3,22]]},"reference":[{"key":"e_1_2_9_2_1","volume-title":"The Essential Physics of Medical Imaging","author":"Bushberg JT","year":"2021"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.12659\/PJR.890745"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.3690466"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1088\/0031\u20109155\/52\/3\/011"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1186\/1748\u2010717X\u20103\u201042"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1117\/12.594520"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600\u20100501.2010.02076.x"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/acm2.12888"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijrobp.2020.10.021.Adaptive"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/acm2.13737"},{"key":"e_1_2_9_12_1","doi-asserted-by":"crossref","unstructured":"StanleyDN PhD HarmsJ et\u00a0al.A roadmap for implementation of kV\u2010CBCT online adaptive radiation therapy and initial first year experiences2022.","DOI":"10.1101\/2022.10.03.22280665"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/mp.14121"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.4864240"},{"key":"e_1_2_9_15_1","unstructured":"Halcyon and Ethos Radiotherapy System:IEC Accompanying Documents Type Tests and Procedures HalcyonTM EthosTM Radiotherapy System.
