Nevertheless, the attainment of high resolution, an extensive measurement area, and the repeatability of dose distribution measurements persist as challenges in clinical practice, thereby often requiring multiple dosimetry systems to overcome measurement constraints. Consequently, there is a significant need to develop a dosimeter that offers both a high resolution and a capability for repeated use.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Purpose<\/jats:title>\n                    <jats:p>A practical scintillation plate dosimeter was designed and its dosimetric characteristics were evaluated using x\u2010ray beams from a linear accelerator.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A practical scintillation plate dosimeter comprised a 0.2\u00a0cm\u2010thick scintillation plate sandwiched between a pair of 2.0\u00a0cm\u2010thick Polymethyl methacrylate (PMMA) plates. A Complementary Metal Oxide Semiconductor (CMOS) camera was used to detect the scintillation light emitted from the scintillation plate when the x\u2010ray beams were delivered to the plate. Measurements were made at 6 MV to test the dose linearity, reproducibility, and dependencies on the camera temperature and angles of incidence. The dose\u2010rate dependency was also measured using 6 and 10 MV flattening filter\u2010free (FFF) beams. The x\u2010ray energy dependency was further tested using 4 MV, 6 MV, 10 MV, 6 MV FFF, and 10 MV FFF beams.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A maximum linearity error of 0.4% was observed for doses ranging from 10 to 1000 MU. The coefficient of variation for the dose reproducibility was\u00a0\u00b1\u00a00.062%, the temperature dependency was 0.07%\/\u00b0C, and the angular variations were within\u00a0\u00b1\u00a01.3% after the removal of Cherenkov light. The dose output decreased by 5.0% at 45 MU\/min, compared with that at 1300 MU\/min with the 6 MV FFF beams, and by 2.0% at 160 MU\/min, compared to 1900 MU\/min with the 10 MV FFF beams.
