Figure 1: Measured beam positions by the CMOS detector, highlighting the intentionally misdelivered spot. The CMOS detector was then irradiated with two clinical style fields to assess clinical practicability. A comparison of the first energy layer between the TPS dose map and the CMOS detector can be seen in Figure 2. Due to current dead time limitations, a thorough qualitative gamma comparison is not possible owing to missed spots, however many of the key features of the clinical plan (local hot-spots, overall shape) are visible in the CMOS measurement.
