Abstract
A system and method are disclosed for allowing the user to change the patient table position or x-ray detector position during an angiographic roadmapping procedure while still displaying a properly registered roadmap display by adapting the mask image to the new position. A system and method are further disclosed for allowing the user to change the field of view size (i.e., zoom factor) of the x-ray detector during an angiographic roadmapping procedure by matching the size of the existing mask to the live image.
Claims42
A method for adjusting an angiographic roadmapping mask, comprising:
- obtaining an original roadmapping mask of a targeted patient tissue region;
- obtaining a live fluoroscopic image of at least a portion of the targeted patient tissue region using an x-ray source and an x-ray detector;
- sensing a change comprising at least one of:
- a position change of a patient table, a change in a distance between the x-ray source and the x-ray detector, and a change in a field of view of the x-ray detector;
- adjusting the roadmapping mask to match the live fluoroscopic image in response to the sensed change;
- and
- combining the adjusted roadmapping mask and the live fluoroscopic image to provide a displayed superimposed image to a user.
A method for performing angiographic roadmapping, comprising:
- obtaining an original roadmapping mask of a targeted patient tissue region using an x-ray source and an x-ray detector;
- obtaining a live fluoroscopic image of at least a portion of the targeted patient tissue region;
- sensing a change comprising at least one of:
- a position change of a patient table, a change in a distance between the x-ray source and the x-ray detector, and a change in a field of view of the x-ray detector;
- adjusting the original roadmapping mask to match a portion of the live fluoroscopic image in response to the sensed change;
- and
- combining the adjusted roadmapping mask and the live fluoroscopic image to provide a displayed superimposed image to a user.
A system for adjusting an angiographic roadmapping mask, comprising:
- an x-ray source, an x-ray detector, a patient table, a display;
- and
- a machine-readable storage medium encoded with a computer program code such that, when the computer program code is executed by a processor, the processor performs a method comprising:
- obtaining an original roadmapping mask of a targeted patient tissue region;
- obtaining a live fluoroscopic image of at least a portion of the targeted patient tissue region using the x-ray source and the x-ray detector;
- sensing a change comprising at least one of:
- a position change of a patient table, a change in a distance between the x-ray source and the x-ray detector, and a change in a field of view of the x-ray detector;
- adjusting the original roadmapping mask to match a portion of the live fluoroscopic image in response to the sensed change;
- combining the adjusted roadmapping mask and the live fluoroscopic image to provide a superimposed image;
- and
- displaying the superimposed image to a user via the display.
