摘要： An X-ray apparatus including an X-ray source, a rotation mechanism which rotates the X-ray source about a rotational axis, and an X-ray detector having a plurality of detection elements. A blocking member defining a slit structure is provided between the X-ray source and the X-ray detector. The slits of the blocking member include two rows aligned in a channel direction of the detector elements, and two rows staggered in the channel direction, thereby to obtain a CT image with improved spatial resolution. Alternatively, instead of using a blocking member, some of the detection elements of at least one detection segment are staggered in the channel direction with respect to detection elements of another detection segment.

摘要： According to the present invention, a subject is prompted to take breaths that are different at least in depth, and the subject's motion associated with respiration is captured. A timing when the subject is scanned is controlled according to the captured motion of the subject associated with respiration. A two-dimensional detector formed like a two-dimensional plane detects an X-ray beam having passed through the subject. Data is collected from the two-dimensional detector to acquire volume data on the subject.

摘要： A CT value of an image within a region of interest is calculated with time. While the calculated CT value does not exceed a predetermined threshold value, a reconstruction mode used when an image is reconstructed from projection data is set to half reconstruction. On the other hand, while the calculated CT value exceeds a predetermined threshold value, the reconstruction mode is set to segment reconstruction.

摘要： An X-ray CT apparatus has a setting unit, a generating unit, a calculation unit, and a determination unit. The setting unit sets a required width of a group of X-ray detection elements in a row direction, which is relatively insusceptible to an influence of a cone angle of a cone-beam X-ray. The generating unit generates accumulation data by accumulating first projection data, based on first X-ray detection elements within the required width included in the group, with same channel in the row direction in preference to second projection data based on second X-ray detection elements outside the required width included in the group. The calculation unit obtains a motion amount for each heartbeat phase based on the accumulation data. The determination unit determines a specific heartbeat phase based on the motion amount for the each heartbeat phase.

摘要： An image processing apparatus is provided for reducing noise from an original image consisting of digital image data. The apparatus has an information calculator, smoothed image producer, weighting-factor calculator, and weighting adder. The information calculator calculates information in relation to a pixel-value change representing a degree that becomes larger with a spatial change in a pixel value averaged each predetermined area on the original image. The smoothed image producer produces a smoothed image by smoothing the original image. The weighting-factor calculator calculates a weighting factor depending on the calculated information in relation to the pixel-value change. The weighting adder mutually performing, using the weighting factor, weighting addition with either the original image or an image modulated from the original image and the produced smoothed image.
