The experimental results (left) and schematic (right) of the Čerenkov dosimetry imaging system, acquiring 2D projection views, and used for 3D reconstruction filtered backprojection imaging of the images [21]. The square MegaVolt photon beam profile (top left) and the complex beam profile (bottom right), were tomographically imaged with the camera, and the sonogram data reconstructed with filtered back projection.
