| 摘要 |
Disclosed herein is a framework for facilitating synchronized image navigation. In accordance with one aspect, at least first and second medical images are received. A non-linear mapping between the first and second medical images is generated. A selection of a given location in the first medical image is received in response to a user's navigational operation. Without deforming the second medical image, a target location in the second medical image is determined by using the non-linear mapping. The target location corresponds to the given location in the first medical image. An optimized deformation-free view of the second medical image is generated based at least in part on the target location. While the user performs navigational operations on the first medical image, the framework repeatedly receives the selection of the given location, determines the target location using the non-linear mapping, and generates the optimized deformation-free view of the second medical image based at least in part on the target location. |

1. A method of synchronously navigating images, comprising:
(i) receiving, by a computer system, at least first and second medical images; (ii) generating, by the computer system, a non-linear mapping between the first and second medical images in response to addition, re-positioning or deletion of one or more anchor landmarks that anchor the non-linear mapping; (iii) receiving, by the computer system, a selection of a given location in the first medical image in response to a user's navigational operation; (iv) applying, by the computer system, the non-linear mapping to coordinates of only the given location, without deforming the second medical image, to determine coordinates of a target location in the second medical image that corresponds to the given location in the first medical image; (v) generating, by the computer system and based at least in part on the target location, an optimized deformation-free view of the second medical image; and repeating steps (iii), (iv) and (v) while the user performs navigational operations on the first medical image. |
