Screenshot from the Siemens Syngo TPS, showing the CT data of the head phantom together with the dose distribution for a carbon field in three sections (top left: from the side; top right from the top; bottom left: beam’s-eye-view). The measurement positions are displayed in each section as the white circles. The measured doses and dose gradients for the 24 ionization chambers are shown in the bottom right. Here, also the three rows (left to right) with eight chambers each (top-down) can be seen in one plane
