Investigation of commercial-grade flatbed scanners and a medical-grade scanner for radiochromic EBT film dosimetry The effectiveness of lower cost "commercial-grade" scanners for film dosimetry purposes was investigated. ... Characteristics of ISP EBT GAFchromic film were evaluated on the following commercial-grade flatbed scanners: Epson 750 Pro ($800), Microtek ArtixScan 1800f ($1500), and Microtek ScanMaker 8700 ... used to set the current standard benchmark of medical-grade film scanners. Analog to Digital (A/D) Scanner Value vs. Optical Density was performed twenty times over several ... of A/D values for each OD step. Repeatability of a scanner was tested by measuring the percent difference between the maximum and minimum A ... OD was defined as the last OD step whose range of A/D scanner values do not overlap with its neighboring OD step. Once overlap occurs the ... dose curve that utilized a larger range of OD values than the other scanners, giving a more gradual change in dose with respect to a change in ...
