- Evaluation of Display Performance for Medical Imaging Systems in the cities Salvador (BA) and Florianópolis (SC) Igor Fernando Modesto Garcia Paulo Mauricio Almeida Geambastiani Mário de Jesus Ferreira Eric Matos Macêdo Marcus Vínicius Teixeira Navarro Daniele Andrade Correia de Jesus Handerson Jorge Dourado Leite Biología Evaluation performance diagnostics display devices The objective of this study was to evaluate the performance of medical imaging systems in the city of Salvador (BA) and Florianópolis (SC). Materials and methods: were evaluated 15 display devices which are used to diagnose in 5 health institutions, according to the methods described in AAPM report 03 and the Spanish protocol. Were verified 9 parameters, comprising 13 tests (quantitative and qualitative) and grouping a total of 29 compliance criteria for each display device analyzed. The instrumentation used in the execution of the tests has traceability to RBC and NIST. Results and discussion: characterization of the sample indicated that 6 display devices were not indicated by the manufacturer for such use, and one of them is of the commercial display device type. The parameters that presented the best and the worst results were respectively, geometric distortion with 100% and luminance dependence with 0% of compliance. The commercial display device was the only display device in the sample that did not conform to the resolution and veiling glare parameters, also showed a significant deviation of 76% from the contrast response of the DICOM GSFD standard. Results of geometric distortion, resolution, veiling glare and noise tests corroborate with other studies and indicate that the current technologies used for medical display devices (LCD and LED) optimize their performance for these parameters. Conclusions: There are nonspecific display devices for diagnosis being used for these purposes and the display devices declared by the manufacturers as diagnostic specific on average showed a higher compliance rate. 2019 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280899020 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.3 Vol.7
