Abstract
A system and method includes determination of a projection axis associated with the two-dimensional projection image, generation of a second two-dimensional image from the three-dimensional image based on the projection axis, registration of the two-dimensional projection image with the second two-dimensional image, combination of the registered two-dimensional projection image with the three-dimensional image in a plane of the three-dimensional image substantially orthogonal to the projection axis, and display of the combined image.

A system comprising:
- a storage device to store:
- a two-dimensional projection image of internal structures of a patient volume;
- and
- a three-dimensional image of the internal structures of the patient volume;
- a processor to:
- determine a projection axis associated with the two-dimensional projection image;
- generate a two-dimensional image of the internal structures of the patient volume from the three-dimensional image based on the projection axis;
- register the two-dimensional projection image with the two-dimensional image;
- determine a plane of the three-dimensional image which is substantially orthogonal to the projection axis and includes a region of interest of the patient volume;
- generate a combined image by inserting the registered two-dimensional projection image in the plane of the three-dimensional image, which is substantially orthogonal to the projection axis and includes the region of interest of the patient volume, and inserting the two-dimensional image in the plane of the three-dimensional image, which is substantially orthogonal to the projection axis and includes the region of interest of the patient volume;
- receive an instruction to change a first opacity of the two-dimensional projection image, a second opacity of the three-dimensional image, a third opacity of the two-dimensional image in the combined image;
- and
- in response to the instruction, change the first opacity of the two-dimensional projection image, the second opacity of the three-dimensional image, and the third opacity of the two-dimensional image in the combined image to generate a second combined image, wherein the changed first opacity is different from the changed second opacity and the changed third opacity is different from the changed first opacity and the change second opacity;
- and
- a display to display the combined image and the second combined image.
