摘要： A semiconductor radiation monitor (i.e., dosimeter) is provided that has an oxide charge storage region located on a first side of a semiconductor fin and a functional gate structure located on a second side of the semiconductor fin that is opposite the first side. Charges are created in the oxide charge storage region that is located on the first side of the semiconductor fin and detected on the second side of the semiconductor fin by the functional gate structure. Multiple semiconductor fins in parallel can form a dense and very sensitive semiconductor radiation monitor.

摘要： An image obtainment unit obtains plural radiographic-images generated by arranging plural storable-phosphor-sheets in such a manner that at least portions of the sheets are overlapped with each other in an irradiation direction of radiation, by arranging a marker at a position to be detected by the plural sheets, and by detecting the radiation that has passed through a subject and the marker by each of the plural sheets. A first-information obtainment unit obtains first-information representing a distance between detection surfaces of the plural sheets. A second-information obtainment unit obtains second-information representing a magnification ratio of a second marker image of the marker included in a radiographic-image obtained by a second sheet with respect to a marker image of the marker included in a radiographic-image obtained by a first sheet of the plural sheets. A distance calculation unit calculates, based on the first and the second information, a radiation-source-to-image-surface distance.

摘要： 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.

摘要： An image detector is disposed behind a grid. The image detector has normal pixels and measurement pixels. Out of a group of measurement pixels based on which an average value of dose measurement signals is calculated, a [C/D] number of measurement pixels are disposed or chosen in a cycle Z=(R×C)±D. Wherein, C represents a cycle of a repetition pattern appearing in an arrangement direction of X-ray transparent layers and X-ray absorbing layers in an X-ray image of the grid, and is represented in units of the number of pixels. R represents a natural number of 0 or more. D represents an integer less than the cycle C. [C/D] represents a maximum integer equal to or less than C/D. Provided that at least the [C/D] number of measurement pixels are shifted C occasions by one pixel, if D=1, the average value of the dose measurement signals is invariable without any variations.

摘要： Embodiments of the disclosure relate to projection-based volumetric dose estimation for X-ray systems, such as X-ray imaging systems. For example, in one embodiment, an X-ray system is capable of estimating an X-ray dose based on an energy interaction of the X-rays with respective portions of an object. In another embodiment, the X-ray dose estimate may be provided on a per voxel, per region, and/or per organ basis.
