Abstract
One aspect of the present disclosure involves a medical imaging system and a method for displaying images of medical devices deployed within a body of a patient in relation to images of anatomical structures of the body. Because of various operating constraints, the images may have been acquired from different coordinate systems at different times. Three-dimensional (3D) positions of physical and virtual sensors in addition to phases of a body organ may be used in associating the images from the different coordinate systems. The system may also compensate for any movement of the patient along an operating table, as well as for movement caused by respiratory and cardiac activity.
Claims20
A system for displaying an anatomy of a body of a patient, the system comprising:
- an imager for acquiring a first image of the anatomy of the body in a first time period and for acquiring a second image in a second time period, the second image showing one or more of:
- the anatomy of the body, and
- a medical device positionable on or within the body;
- a first anchor physically or virtually positionable on or within the body, the first anchor remaining substantially fixed on or within the body in the first and second time periods;
- a database for storing the first image;
- a medical positioning system (MPS) for determining three-dimensional (3D) positions of the first anchor in the first and second time periods;
- a processor for associating the 3D positions of the first anchor with the first and second images and for associating the first image with the second image based on the 3D positions of the first anchor;
- and
- a display for presenting a resultant image formed by the association of the first and second images.
A method for displaying an anatomy of a body of a patient, the method comprising:
- affixing an anchor physically or virtually on or within the body;
- acquiring a first set of images of the anatomy of the body and storing the first set of images in a database;
- acquiring a second image showing one or more of:
- the anatomy of the body, and
- a medical device disposed within the body;
- determining a three-dimensional (3D) position of the anchor when each of the first set of images and the second image are acquired;
- retrieving one of the first set of images from the database;
- and
- associating the retrieved one of the first set of images with the second image based on the 3D positions of the anchor.
A system for displaying a medical device in relation to an anatomy of a body of a patient, the system comprising:
- a first imager for acquiring a first set of images of the anatomy of the body in a first time period;
- a second imager for acquiring a second set of images in a second time period, the second set of images showing the medical device disposed within the body of the patient;
- a first organ sensor for sensing a phase of a body organ in the first time period as each of the first set of images is acquired;
- a second organ sensor for sensing a phase of the body organ in the second time period as each of the second set of images is acquired;
- a sensor affixed to the body of the patient, the sensor remaining substantially affixed to the body in the first and second time periods;
- a first medical positioning system (MPS) for determining a three-dimensional (3D) position of the sensor in the first time period;
- a second MPS for determining a 3D position of the sensor in the second time period;
- a processor for associating the 3D positions of the sensor and the sensed phases of the body organ with the first and second set of images, the processor for associating one of the first set of images with one of the second set of images based on the 3D positions of the sensor and based on the sensed phases of the body organ;
- and
- a display for presenting a resultant image formed by associating one of the first set of images and one of the second set of images.
