Abstract: Some embodiments can comprise a tomographic imaging data acquisition method(s) and/or systems embodying the method(s). Some methods according to embodiments of the invention include simultaneously reading each photoconverter of a scintillation detector; reading the photoconverters at a frequency sufficient to obtain a plurality of digital sample measurements of a scintillation wave front; and recording the data read from each of the plurality of photoconverters as a function of time.

Abstract: A slab detector for PET and/or SPECT imaging comprising a scintillation crystal slab and a plurality of photoconverters each in optical communication with a surface of the scintillation crystal. In some embodiments, the plurality of photoconverters define a two dimensional array, wherein each photoconverter abuts adjacent photoconverters. Furthermore, according to some embodiments a plurality of slab detectors can be juxtaposed with one another so that their slab crystals abut edgewise.

Abstract: Some embodiments include a low-dose CT apparatus. Such an apparatus can comprise a plurality of x-ray sources disposed on a gantry and spaced apart along a z-axis. The sources may be configured to produce substantially overlapping fan beams, wherein overlap is substantially complete at a detector surface. Some embodiments also include a controller in electronic communication with the plurality of x-ray sources. The controller may be adapted to switch the plurality of x-ray sources between on and off states such that only one x-ray source is in an on state at any time. Furthermore, the controller circuit may be in electronic communication with at least one x-ray detector and may be adapted to synchronize the x-ray detector with the plurality of x-ray sources such that detected x-rays can be matched to an x-ray source.
