Abstract: The application describes an X-ray detector, which uses direct X-ray conversion (DiCo) combined with CMOS pixel circuits. DiCo materials have to be used with high voltage to achieve a high field strength. This makes the sensor prone to leakage currents, which falsify the measured charge result. Moreover, most direct conversion materials suffer from large residual signals that lead to temporal artefacts (ghost images) in an X-ray image sequence. A circuit is described, which senses the sensor's dark current including residual signals from previous exposures before the sensor is exposed (again) to X-ray, and freezes relevant circuit parameters at the end of the sensing phase in such way, that the dark current (leakage current and residual signal) can still be drained during exposure. Therefore, the charge pulses generated in the sensor due to X-ray exposure can be integrated without charges carried by the leakage current or residual signal, thus obtaining a more accurate estimate of the deposited X-ray energy.

Abstract: A method for manufacturing a photo-responsive device having a photo- sensitive layer is proposed. The method comprises the following steps: a) providing a clean substrate inside an evacuated evaporation chamber; b) evaporating lead oxide (PbO) from a first crucible to form a seeding layer on the surface of the substrate; c)affecting upon the seeding layer such that only tetragonal lead oxide forms the seeding layer and/or such that the initially grown orthorhombic lead oxide forming the seeding layer is transformed into tetragonal lead oxide; and d) continuing to evaporate lead oxide until the final thickness of the photo- sensitive layer has been deposited onto the substrate. As a result the method yields a photo- responsive device comprising a photo-sensitive layer of lead oxide, which entirely consists of tetragonal lead oxide.

Abstract: It is described an integrated circuit design and a method to fabricate the same for a high-efficiency, low-noise, position sensitive X-ray detection in particular for medical applications. The device (350) is based on deep recesses (354) filled with an X-ray sensitive scintillator material. A shallow first electrode (360) is formed on the surface of the substrate (352) sidewalls separating two neighboring recesses (354). This sidewall electrode (360) in combination with particular frontside wafer electrode (363) structure results in a full depletion of the entire device (350) and a removal of signal charge towards the low capacitance readout electrode (363). The described integrated circuit element (350) ensures high and not depth dependent light collection efficiency.

Abstract: The invention relates to a detector element for x-radiation, which can be used in particular in a flat dynamic x-ray detector (FDXD). In the detector element, a directly converting conversion layer (2) is arranged between an electrode layer (2) and a matrix of pixel electrodes (4), there also being a photoconductive separating layer (3) between the pixel electrodes (4) and the conversion layer (2). In the unilluminated state, the separating layer (3) acts as an electrical barrier for free charge carriers of the conversion layer (2), which have been produced by x-radiation and migrate in the electric field between the electrodes (1, 4). After readout of the charge transfers in the pixel electrodes (4), the separating layer (3) can be rendered conductive by illumination with reset light from a diode arrangement (6), so that charge accumulations at its interface can flow away. The separating layer (3) can prevent perturbing dark currents, while charge accumulation can at the same time be avoided by the repeated reset phases.
