A method is disclosed for detecting x-rays using an x-ray detector which includes a direct-conversion semiconductor detector element. Additional radiation is supplied to the semiconductor detector element using a radiation source, and the supply of the additional radiation is controlled and/or regulated on the basis of a specified target value. In at least one embodiment, the target value can be specified in a variable manner over time as a sequence of target values. An x-ray detector system is further disclosed, with which the method can be carried out.

An apparatus is disclosed comprising a metal oxide semiconductor capacitor (MOSCAP) comprising one or more gate layers disposed over a contiguous radiation-sensitive insulating layer, wherein the contiguous radiation-sensitive insulating layer comprises one or more contacting dielectric layers. A method may be employed to measure a value of a radiation-induced capacitance response of a metal oxide semiconductor capacitor (MOSCAP) from multiple non-contacting gate layers disposed over a radiation-sensitive layer comprising of one or more contacting dielectric layers to thereby enhance a sensitivity and a resolution of a radiation response of the MOSCAP.

A terminal capable of detecting rays, an enclosure, and a method for fabricating terminal are provided. The terminal comprises a terminal body and a ray detector in communication with the terminal body. The terminal body comprises a display panel. The ray detector detects rays around the terminal, and transmits the detected signal to the terminal body. The terminal body analyzes the detected signal and transmits the detected signal to the display panel for displaying. In the present disclosure, the detector and the display panel are formed at the same time, and the detector is integrated in a same display panel, so that the process is simplified. The terminal stores and analyzes the data about the collected ionizing radiation dose. As a result, the radiation dose can be read in real time, and an alert can be issued instantaneously to reduce unnecessary damage.

A dosimeter includes a substrate and a plurality of nanowire pairs located on the substrate. The plurality of nanowire pairs simulate a plurality of human chromosome pairs. A method of determining an effect of delivering ionizing radiation with a dosimeter having a substrate and a plurality of nanowire pairs located on the substrate, wherein the plurality of nanowire pairs simulate a plurality of human chromosome pairs is provided. The method includes the steps of delivering ionizing radiation to the plurality of nanowire pairs; acquiring information relating to the ionizing radiation; and determining, from the information, the effect of the delivered radiation on the plurality of nanowire pairs.

Systems and methods monitoring progress of procedures by radiation exposure are provided. Position data is received for an equipment item used for the procedure and configured to produce radiation (“radiation device”). Position data is received from the tracking device during the procedure. An estimated exposure level is determined by a controller for the individual based, at least in part, on the position data from the tracking device relative to the position data from the radiation device and compared to a benchmark. If the estimated exposure level for the individual exceeds the benchmark, an electronic notification is generated.

In capturing an image of a grid by an image detector, a measurement pixel that is not in the position of a specific point having a maximum or minimum value of an output signal is referred to as a first measurement pixel, and a measurement pixel that is in the position of the specific point is referred to as a second measurement pixel. The disposition of the first and second measurement pixels are determined so as to satisfy the following condition: fG/fN≠odd number, wherein fG is a grid frequency and fN is a Nyquist frequency of pixels; and in shifting the grid C times by one pixel, the number of the first measurement pixels is larger than that of the second measurement pixels at any time in the range of a cycle C of a repetition pattern appearing in the image.
