no. 2 Embodiment approach

[0113] In the first embodiment described above, the case of generating and displaying a color image related to one Index has been described. In the second embodiment, a case where a color image is generated based on a plurality of Indexes will be described. That is, in the second embodiment, the content of processing by the color image generating unit 267 is different. The following description will focus on this.

[0114]The color image generating unit 267 according to the second embodiment sets an index for changing the color and the state of the color based on a plurality of Indexes. Specifically, the color image generation unit 267 uses two of a plurality of Indexes including PT, AUC, AT, MW, PH, WT, Slope, and MTT as indexes of signal strength to generate an index representing color, On the other hand, it shows the color image of the index which changes the state of the color. Here, the color image generating unit 267 according to the second embodiment uses brightness,...

no. 3 Embodiment approach

[0118] In the first embodiment and the second embodiment described above, the case where the X-ray image and the color image which are black images are displayed differently has been described. In the third embodiment, a case where an X-ray image and a color image are superimposed and displayed will be described. That is, in the third embodiment, the processing content of the display image calculation unit 268 is different. The following description will focus on this.

[0119] The display image computing unit 268 according to the third embodiment superimposes and displays the color image generated by the color image generating unit 267 and the X-ray image. Figure 11 It is a diagram showing an example of a display image generated by the display image calculation unit 268 according to the third embodiment. In addition, in Figure 11 In , a PT image will be described as an example of a color image. For example, if Figure 11 As shown, the display image calculation unit 268...

Abstract

An X-ray diagnosis apparatus includes: a reference value calculating unit that calculates a reference value used for normalizing a flow of a contrast material, on the basis of a chronological transition of a signal intensity of the contrast material in a predetermined region, for each of a plurality of groups of X-ray images chronologically taken while using the contrast material; an index image generating unit that normalizes, for each of the plurality of groups of X-ray images, the flow of the contrast material at each of pixels by using the reference value calculated by the reference value calculating unit and that generates an image in which a feature value of the normalized flow of the contrast material is reflected in each of the pixels; and a displayed image calculating unit that causes a predetermined display unit to display the image generated by the index image generating unit.

Description

technical field [0001] Embodiments of the present invention relate to an image processing device and an X-ray diagnostic device. Background technique [0002] Conventionally, in an X-ray diagnostic apparatus, DSA (Digital Subtraction Angiography) imaging is used when performing angiographic imaging to observe a blood vessel structure. DSA imaging is performed by separately comparing an X-ray image of a state without injection of a contrast agent (hereinafter, appropriately referred to as a "mask image") and an X-ray image of a state with a contrast agent injected (hereinafter, appropriately referred to as a "contrast image"). ”) to collect DSA images that only depict blood vessels by performing subtraction between images. [0003] Here, the DSA image is generated by performing subtraction on both the mask image and the contrast image. Therefore, due to the movement of the subject, there may be position deviation between the two images, for example, in background elements su...
