According to one embodiment, a radiation detector includes a photo-electric conversion substrate, a scintillator layer containing a main material and a dope material and a light reflective layer or a moisture barrier layer, formed on a front surface side of the scintillator layer along a shape of the front surface of the scintillator layer. The scintillator layer includes a mixed layer portion formed of the main material the dope material on the photo-electric conversion substrate, and a dope material layer portion formed of only the dope material on a front surface side of the mixed layer portion. A front surface of at least the dope material layer portion is formed into relatively coarse shape compared to the mixed layer portion.

Various methods and systems are provided for a medical imaging system C-arm. In one embodiment, an imaging system comprises a C-arm including an inner circumferential wall forming a first pair of grooved flanges and the outer circumferential wall forming a second pair of grooved flanges, where each of the first pair of grooved flanges and second pair of grooved flanges comprises a composite material. A C-shaped portion of the C-arm may be configured to rotate isocentrically around a rotational axis.

A sensor substrate is provided with a plurality of pixels for accumulating electrical charges generated depending on light converted from radiation in a pixel region of a flexible base material. A circuit unit includes at least one of a driving substrate, a signal processing substrate, or a control substrate and is electrically connected to the sensor substrate. A fixing plate fixes the circuit unit. A conversion layer is provided on a first surface opposite to a second surface of the fixing plate on which the circuit unit is fixed, is provided in a state where the second surface opposite to the fixing plate side faces the first surface of the base material on which the pixels are provided, and converts radiation into light. A housing houses the sensor substrate, the circuit unit, the fixing plate, and the conversion layer.
