Abstract: A Proton Computer Tomography (pCT) system comprising: a position tracker, able to reconstruct the proton trajectory within the body; an energy detector, able to reconstruct the proton energy; wherein, the position tracker is made up of four Depleted Monolithic Active Pixel Sensors (DMAPS) placed in pairs at either side of a phantom, and the energy detector is a Super Thin Range Telescope located downstream comprising a plastic-scintillator made of layers of thin polystyrene bars oriented in alternate axis, perpendicular to the proton beam.

Abstract: An auxiliary device attachable to a mammography machine having an X-ray source and an X-ray receptor having a receptor area. The auxiliary device includes a housing having a length, width, and thickness, wherein the length and width of the housing are adapted to a length and width of the receptor area. The auxiliary device further includes one or more attachments for attaching the auxiliary device to the mammography machine, and a detector inside the housing. The detector includes a slab of semiconductor material, an electrode on a first side of the slab, and a pixelated electrode detector on the second side of the slab, and a read-out circuit bonded to the pixelated electrode detector, and the read-out circuit being configured for spectral photon counting with two or more energy bins. Methods for medical imaging are also provided.
