US 2006/0186341 A1 · Radiological imaging apparatus and positron emission tomographic apparatus

Abstract

A positron emission tomography apparatus installs a plurality of detector units in the circumference of a bed. The detector unit installs a plurality of combined substrates including detectors, analogue ASICs, and a digital ASIC and a voltage adjustment device inside a housing. A partition plate installed inside the housing separates the region inside the housing into a first region installed with the combined substrates and a second region installed with the voltage adjustment device. The partition plate blocks noise generated in the voltage adjustment device so as not to affect γ-ray detection signals outputted from the detectors, thereby preventing the effect of the noise generated in the voltage adjustment device toward γ-ray detection signals and shortening the examination time.
