Figure Lengend Snippet: Bland–Altman plots with difference between electronic portal imaging device (EPID) and SRS MapCHECK ® for gamma analysis criteria 2% (DD) and 1 mm (DTA). PDIP: portal dose image prediction, PF: PerFRACTION™, 2D: 2-dimensional, 3D: 3-dimensional, DD: Dose Difference, DTA: Distance to Agreement

Article Snippet: To overcome these limitations, new commercial high resolution array detectors, such as myQA SRS (Ion Beam Applications, Germany) and SRS MapCHECK ® (Sun Nuclear Corporation, USA) have been developed and are available for SRS and SBRT QA.

Figure Lengend Snippet: Experimental setup of the MapCHECK2 and additional slabs on the surface. The diodes plane is placed at 100-cm SAD

Article Snippet: The MapCHECK2 with various slab thicknesses of 0, 1, and 3 cm on the top and 3-cm slab below were scanned using a 64 slices Siemens SOMATOM Sensation CT scanner (Siemens, Aktiengesellschaft, Werner-von-Siemens-Straße 1 80333, Munich) (512 × 512 matrix with pixel size of 0.78 mm; slice thickness of 3 mm).

Figure Lengend Snippet: Dose verification of the AP field for the prostate case. The left panel shows the dose distribution (isodose lines) calculated by the KonRad TPS together with the ones measured with the MapCheck device. The right panel shows the vertical profile of the dose distribution. The measured dose points are shown as yellow circles, the calculated dose profile as a solid line. For this field 202 out of 205 points passed the 3%/3mm acceptance criteria.

Article Snippet: The verification plans were generated and the beams from each plan were delivered individually on the MapCheck device using a Siemens Primus linear accelerator.

Figure Lengend Snippet: Characteristics of the used 2D arrays

Article Snippet: Including three of the most often used 2D arrays (MatriXX evolution , Octavius 1500 , MapCHECK2) in one study offers the advantage of better comparability, which helps interpreting differences in gamma‐evaluation studies for plan‐individual QA, in general.
