摘要： An X-ray computed tomographic apparatus includes a gantry, a reconstructing portion, and a tube current value determining portion. The gantry acquires projection data of an arbitrary range in a body axial direction by continuously moving a tabletop on which a subject is laid down and by continuously rotating an X-ray tube about the subject. The reconstructing portion reconstructs image data from the acquired projection data according to reconstruction processing selected by an operator from plural types of reconstruction processing. The tube current value determining portion determines plural tube current values respectively corresponding to discrete, plural positions within the range, on the basis of the selected type of reconstruction processing and an image quality level specified or selected by the operator.

摘要： An X-ray absorptance map associated with an object to be examined is generated on the basis of scanogram data obtained from a predetermined direction of the object, and imaging conditions are determined on the basis of the absorptance map. Before tomography, an index representing a radiation dose in the execution of scan in accordance with the imaging conditions is calculated and displayed, together with the imaging conditions. Every time the imaging conditions are changed, an index representing a radiation dose is calculated and displayed. Tomography is executed in accordance with the finally determined imaging conditions. This makes it possible to reduce the radiation dose to the object and obtain a tomographic image with high quality.

摘要： An X-ray CT scanner comprises an X-ray source generating an X-ray, detector detecting the X-ray transmitted through an object, processor to produce projection data, and reconstruction unit to reconstruct an image using the projection data. The processor produces the projection image by applying, to an output signal from the detector, logarithm conversion processing on a function deviating from an ideal logarithm function. The ideal logarithm function is a logarithm function defined by a mathematical formula of y=K·log [b, x] (wherein a variable x is an input, a variable y is an output, and a reference K shows a scaling constant). The function deviating from the ideal logarithm function has an input/output characteristic deviating from that of the ideal logarithm function. Such deviating function is for example a linear function and applied to a conversion of only low-count data into its projection data to suppress low-count artifacts on reconstructed CT images.
