Angiography and intracavity image registration interaction method, device, equipment and medium

The embodiment of the invention discloses a radiography and intracavity image registration interaction method and device, equipment and a medium. The method comprises the steps that in an angiography image area on a registration interaction interface, angiography image data of a target blood vessel is displayed, and the angiography image data at least comprises a first index identifier for marking the index position of the target blood vessel; in an intracavitary image area on the registration interaction interface, intracavitary image data of the target blood vessel is displayed, and the intracavitary image data at least can comprise a second index identifier for marking an index position; and in response to a movement operation for the displayed first index identifier or the second index identifier, displaying the moved first index identifier in the contrast image area and displaying the moved second index identifier in the intracavity image area. According to the technical scheme provided by the embodiment
