[0026] figure 1 It is a block diagram showing an example of the configuration of the X-ray diagnostic apparatus 10 in the first embodiment of the present invention. Also in the second to sixth embodiments described later, the hardware configuration of the X-ray diagnostic apparatus 10 is the same as that of the first embodiment. Here, as an example, the constituent elements of the X-ray diagnostic apparatus 10 are divided into three, namely, a bed apparatus 20 , an X-ray generating and detecting system (X-ray generating and detecting system) 30 , and a computer system (computing system) 40 .
[0027] First, the bed apparatus 20 has a support table 21 , a top board 22 , and a top board moving mechanism 23 arranged inside the support table 21 . The subject P is placed on the top plate 22 . Here, as an example, the subject P is provided with the guide wire manipulation device 200, which will be described in the sixth embodiment.
[0028] The support table 21 supports the top p...

[0143]The second to fifth embodiments are the same as the first embodiment except for the difference in which DSA image or parameter image is used as the source for generating the composite image of the latest phase. In the second to fifth embodiments, only differences from the other embodiments will be described.
[0144] In the second embodiment, among the two images from which the composite image of the latest time phase is generated, one image is a parameter image corresponding to the latest time as in the first embodiment, and the other image is unified as the selected DSA image of 1 time phase.
[0145] Figure 7 It is a schematic diagram showing an example of a synthesized image of the latest time phase generated by synthesizing the DSA image of the selected time phase and the parameter image corresponding to the latest time in the second embodiment. Figure 7 The left side of the upper segment represents an example of a DSA image of the selected phase, Figure 7 The...

[0167] Since the third embodiment is the same as the second embodiment except for the following points, only the different points will be described. That is, in the third embodiment, one of the two images from which the composite image of the latest time phase is generated is not the DSA image of the selected one time phase, but is unified into the selected interval (temporally continuous The average image of multiple) DSA images.
[0168] In the case of the post-processing step, the user can select, via the input device 48 , a section in which a lesion candidate region such as a tumor is projected most densely due to the contrast agent.
[0169] Figure 9 It is a flowchart showing an example of the operation of the X-ray diagnostic apparatus 10 in the case where the synthesized image is updated and displayed following the fluoroscopy performed in real time in the third embodiment. Here, as an example, until a section of the DSA image is selected by the user's input, it oper...
