Figure Lengend Snippet: Schematic layouts of our conventional IMRT QA are shown. ( a ) The absolute point dose was measured using a PinPoint ionization chamber, which was inserted into the I'm RT Phantom. ( b ) The composite planar dose was measured using a GAFCHROMIC EBT3 film, which was also inserted into the phantom in the axial plane. ( c ) Per-field coronal planar dose was measured at a gantry angle of 0° using a MapCHECK device with Tough water of 80-mm thickness that resulted in a depth of 100 mm.

Article Snippet: The MapCHECK was placed on the treatment couch with Tough water (Kyoto Kagaku Co. Ltd, Kyoto, Japan) of 80-mm thickness that resulted in a depth of 100 mm.

Figure Lengend Snippet: The results of gamma evaluation for the per-field measurement are shown. The horizontal axis shows the number of IMRT cases, and the vertical axis is the percentage gamma passing rate. Data were analyzed using accessory software included in MapCHECK device, and the dose differences were evaluated using the 3%(global)/3 mm criterion with a 10% lower dose threshold.
