X-Irradiation setup. To irradiate the platelet products, an “X irradiation system” consisting of a LINAC treatment machine and a phantom was applied. (A) shows an irradiation box (phantom) designed and constructed in this project to accommodate a single platelet product. This phantom is fabricated using Perspex and the internal/ external dimensions and thickness are 25 × 17 × 2 cm3, 29 × 21 × 6 cm3 and 2 cm, respectively. The lid of the phantom is also made of Perspex with dimensions and thickness of 21 × 6 cm2 and 2 cm to be sure that the platelet product is located behind the build-up region of the 6 MV photons and keep the experiment more precise and reproducible. A specific space allocated within the phantom as an ionization chamber to place a dosimeter (e.g., farmer) for online monitoring on demand. (B) demonstrates a sample view of treatment planning results for the filled phantom, in which green isodose dedicates the regions which are expected to get at least 95% of the prescribed dose. (C) displays phantom set up at the treatment room on the LINAC table.
