Abstract: A marker-coordinate detecting unit detects coordinates of a stent marker on a new image when the new image is stored in an image-data storage unit; and then a correction-image creating unit creates a correction image from the new image through, for example, image transformation processing, so as to match up the detected coordinates with reference coordinates that are coordinates of the stent marker already detected by the marker-coordinate detecting unit in a first frame. An image post-processing unit then creates an image for display by performing post-processing on the correction image created by the correction-image creating unit, the post-processing including high-frequency noise reduction filtering-processing, low-frequency component removal filtering-processing, and logarithmic-image creating processing; and then a system control unit performs control of displaying a moving image of an enlarged image of a set region that is set in the image for display, together with an original image.

Abstract: A medical imaging apparatus for generating medical information includes an input unit, a processor, and a display. The input unit is operated by a user and is configured to input an instruction. The processor is configured to process a first part of display information relating to the medical information based on the instruction so that the first part is displayed in a differentiable manner from others of the display information. The display is configured to display the processed first part and the others of the display information.

Abstract: In preferred embodiments, a fast spin echo imaging technique is provided that is insensitive to violations of the Carr Purcell Meiboom Gill (CPMG) condition. Diffusion gradients disrupt the CPMG condition, and, hence, the present fast spin echo method is compatible with diffusion measurements and diffusion weighted imaging. The preferred embodiments of the present technique involve splitting of spin echoes into echo pairs. Spin echoes are split by adjustment (in magnitude or duration) of an initial readout gradient pulse. A train of echo pairs is captured. A first image is constructed using the first echoes of each pair. Also, a second image is constructed using the second echoes of each pair. Hybrid radial Cartesian methods are used for constructing the first and second images. The first and second images are constructed independently of one another. Independent image construction renders the method insensitive to violation of the CPMG condition. Finally, the two images are combined to form a final image.

Abstract: A magnetic resonance imaging apparatus 20 includes a scan executing unit that executes scan to generate sensitivity map data of an RF coil 24, a region reduction unit 44b that applies region reduction to a signal region near a no-signal region of image data obtained by the scan, a sensitivity map data generating unit 44 that generates sensitivity map data using image data after the region reduction, and a smoothing processing unit 44i that applies three-dimensional smoothing filter to the sensitivity map data.

Abstract: For isotropic diffusion weighting during magnetic resonance imaging, a motion-probing magnetic field gradient pattern is manufactured from a template by searching for an optimum value of a skew parameter (?) of the template. The gradient pattern includes a first pattern before at least one RF refocusing pulse and a second pattern after the refocusing pulse in which the second pattern is symmetrical with the first pattern. For example, gradient coils produce a respective gradient component along each of three orthogonal directions, and for each component and each pattern, the gradient pattern has one cycle of opposite polarity lobes about a crossing point, and for each pattern, the crossing point of the cycle in one of the orthogonal directions is a midpoint of the cycle; and the skew parameter (?) specifies a difference in time between the crossing points of the cycles in the other orthogonal directions.
