    摘要: In a method and a device MR images having various contrasts are scanned and then values for some or all of the parameters T1, T2 and PD related to the scanned MR images are determined. Based on the scanned MR images and the determined parameter values an initial conventional MR contrast image with some default scanner settings is generated, or alternatively, a stronger non-physical MR contrast image. The initial MR contrast image can then be manipulated by a user in response to movement of a user-controlled marker on a screen showing the contrast image such that a contrast optimized image can be obtained for a particular diagnosis in a very short time. Furthermore a quantitative image can be generated representing the amount of a single tissue type.

    摘要: A segmented MR image is provided by measuring a number of Magnetic Resonance Imaging parameters on an absolute scale. For example T1 relaxation, T2 relaxation and Proton Density PD can be measured on an absolute scale. The absolute values are then compared with known values for at least one type of tissue. For human tissue these parameters typically are in the order 300-4500 ms for T1, 50-1000 ms for T2 and 0-100% water for PD. Both T1 and T2 depend on the field strength. Based on a comparison between normal values for a particular type of tissue the values obtained for the image each pixel/voxel can be labeled with a certain probability that the voxel contains this type of tissue and segmented accordingly.

    摘要: In a method of displaying settings for a Magnetic Resonance (MR) image, a visual marker is displayed in a window. The coordinates of the visual marker correspond to T1 weighting of the MR image along a first axis of a display and correspond to T2 weighting of the MR image along a second axis of a display window.

    摘要: A low profile radio frequency coil (32, 44, 441, 442, 443) for use in a magnetic resonance imaging system includes a low profile antenna (34, 102, 202, 302) that is configured to resonate at about a magnetic resonance frequency of the magnetic resonance imaging system. A generally planar inductor (110, 112, 210, 240, 310) is electrically connected or coupled with the low profile antenna. The generally planar inductor provides selected frequency filtering of a radio frequency signal received by or transmitted by the low profile antenna.
