acquiring three-dimensional parameters required by the rotation of the marked medical image;
and carrying out space position transformation on the marked medical image according to the three-dimensional parameters so as to enable the mark of the marked medical image to be overlapped with a preset reference mark.
9. A medical image display apparatus, characterized by comprising: an acquisition module, a marking module, an adjustment module, a matching module and a display module, wherein,
the acquisition module is used for acquiring a medical image;
the marking module is used for marking a target area in the medical image to obtain a marked medical image;
the marking module is specifically used for setting a straight line along a central line of a target area in the medical image as the mark according to the medical image to obtain a marked medical image;
the adjusting module is used for acquiring a spatial transformation relation between a mark of the marked medical image and a preset reference mark in an image display area and adjusting the marked medical image according to the spatial transformation relation; the preset reference mark is a preset reference object in the image display area and comprises an x axis and a y axis of a preset coordinate system;
the matching module is used for obtaining an observation image if the mark of the marked medical image in the image display area is matched with the preset reference mark;
the matching module is specifically used for obtaining the observation image if the mark for marking the medical image in the image display area is overlapped with the preset reference mark; if the mark of the marked medical image in the image display area is parallel to the x axis or the y axis of the preset coordinate system, obtaining the observation image; if the mark of the marked medical image in the image display area is mutually staggered with the x axis or the y axis of the preset coordinate system and meets a preset angle, obtaining the observation image;
the display module is used for displaying the observation image.
10. A storage medium on which a computer program is stored which, when being executed by a processor, carries out the steps of a medical image display method according to any one of claims 1 to 8.
