Embodiment Construction

[0031] figure 1 A schematic method sequence of the method according to the invention is shown. In this exemplary embodiment, the method is used to display the surface structure of the patient's brain on a monitor without the view of the brain being obstructed by the skull.

[0032] For this purpose, in step 101, the patient's head is scanned by means of a magnetic resonance tomography system and first MR image data of the head are subsequently generated, wherein during the scan the scan parameters are selected in such a way that in the first MR image data The region of interest of the scanned examination object has a high signal intensity, while the non-interest region of the examination object has a relatively low signal intensity. In this case, acquisition parameters corresponding to so-called diffusion-weighted magnetic resonance tomography are selected for this purpose.

[0033] In step 102 , a mask is generated on the basis of the first MR image data, with which regions...

Abstract

The present invention relates to a method for collecting and displaying image data, particularly MR image data. The method comprises the following steps: 1.1 scanning a checking object by means of a magnetic resonance tomography device and subsequently generating first MR image data of the checking object, wherein, the scanning parameters in scanning are selected so that the interested area of the checking object scanned in the first image data has high image data value and the non-interested area of the checking object has relatively lower image data value comparatively; 1.2 generating a mask based on the first image data, wherein the area with small signal strength in the first image data can fade out with the mask; 1.3 scanning the checking object by means of the imaging medical system and generating the second image data of the checking object; 1.4 applying the mask to the first and / or second image data; and 1.5 displaying the first and / or second image data which is processed by the mask.

Description

technical field [0001] The invention relates to the field of medical technology and describes a method for acquiring and displaying medical image data, in particular MR image data (MR: Magnetic Resonance). Background technique [0002] Magnetic resonance imaging (MRI, English: Magnetic Resonance Imaging) is known to be able to show especially 1 H atom, 31 P atoms and 123 Density of the nuclear spins of Na atoms as a function of position in the volume of the object under examination. In this case, different tissue types are represented in the MR image with different signal intensities, which are essentially based on different spin relaxation times in the tissue. The signal intensities acquired by the magnetic resonance tomography system during a scan, which are associated with the relevant voxel of the object under examination, depend on a number of parameters and are typically imaged in the image data as corresponding grayscale values. Thus, in magnetic resonance tomogra...
