Abstract: A particle beam radiotherapy system has been proposed by using a set of first and second scatterers, whereby a short-duration pulse beam is irradiated to a lesion. When the duration of the radiotherapy beam is 200 milliseconds or less, healthy tissues are selectively protected and only cancer tissues are damaged. For example, it can be used for cancer treatment of brain metastases that may be distributed throughout the entire brain tissues. The positions of the scatterers and the energy of the incident particle beams are optimized according to the position and the volume of the brain tissues.

Abstract: An improved x-ray cone-beam CT image reconstruction by end-to-end training of a multi-layered neural network is proposed, which employs cone-beam CT images of many patients as input training data, and precalculated scattering projection images of the same patients as output training data. After the training is completed, scattering projection images for a new patient are estimated by inputting a cone-beam CT image of the new patient into the trained multi-layered neural network. Subsequently, scatter-free projection images for the new patient are obtained by subtracting the estimated scattering projection images from measured projection images, beam angle by beam angle. A scatter-free cone-beam CT image is reconstructed from the scatter-free projection images.
