Combination of Multi-Modality Imaging Technologies
First Claim
1. A method for positioning a device for accessing a target region in a patient, comprising:
- determining (910) at least one of a particular path and a particular viewpoint for accessing the target region based on at least one 3-D image of the target region obtaining by imaging the target region; and
controlling (920) the device for accessing the target region according to the at least one of a particular path and a particular viewpoint.

Abstract
Different applications for multiple imaging technologies are provided to advance patient care. In one aspect, a 3-D imaging device is used to identify the location of target region in a patient, such as a tumor or aneurysm, for instance. The location information is then used to control a device used in performing a surgical or other intervention, further imaging or a diagnostic or therapeutic procedure (920). The device can operate fully automatically, as a robot, or can assist a manual procedure performed by a physician. In another aspect, the invention provides a technique for obtaining an improved image of the vasculature in a patient (1020). In another aspect, images from multiple imaging technologies are combined or fused (1120) to achieve synergistic benefits.

16. A method for obtaining an image of vasculature in a target region in a patient, comprising:
-
imaging (1000) the target region using a 3-D imaging device without injection of a contrast agent to obtain a first image; imaging (1010) the target region using the 3-D imaging device with injection of the contrast agent to obtain a second image; and obtaining (1020) a subtraction image comprising the vasculature in which the contrast agent is carried based on differences between the first and second images. - View Dependent Claims (17, 18)
