Abstract
In a method, sensor and system for producing time-limited images of a moving organ of a human or animal body, an imaging apparatus acquires image data and, using a sensor situated outside the body, a signal is registered that represents the movement of the organ that is to be imaged. The image data acquisition is coordinated with this signal. A fiber optic sensor is used as the sensor.
Claims24
A method for producing a time-limited image of a moving organ in a living subject, comprising the steps of:
- acquiring image data of a moving organ in a living subject using an imaging modality;
- disposing a fiber optic sensor exclusively at an exterior of said subject and obtaining a signal from said fiber optic sensor representing movement of said moving organ;
- and
- correlating acquisition of said image data with said signal, to obtain a time-limited image of said moving organ.
A fiber optic sensor for acquiring a signal representing movement of an internal moving organ in a living subject, comprising:
- a light waveguide arrangement comprising a light supply conductor and a light return conductor, and
- a coupling device disposed relative to said light supply conductor and said light return conductor to couple light from said light supply conductor into said return conductor, said coupling device being adapted to interact exclusively with an exterior of a living subject in which a moving organ is disposed, and said coupling device coupling said light dependent on an external force generated by said moving organ and acting on said coupling device.
A system for producing a time-limited image of a moving organ in a living subject, comprising:
- an imaging modality adapted to interact with a living subject to acquire image data of a moving organ in the subject;
- a fiber optic sensor adapted to be disposed exclusively at an exterior of said subject and obtaining a signal from said fiber optic sensor representing movement of said moving organ;
- and
- a computerized control arrangement connected to said fiber optic sensor and to said imaging modality that controls operation of said imaging modality to correlate acquisition of said image data with said signal, to obtain a time-limited image of said moving organ.
A device for displaying a time-limited image of a moving organ in a living subject, comprising:
- a mark reader supplied with image data of a moving organ acquired with an imaging modality and correlated with a signal obtained from the subject during acquisition of the image data, said signal representing movement of the moving organ;
- a display device connected to said mark reader for displaying a sequence of images of the moving organ produced from said image data;
- and
- a signal output device supplied with said signal that emits an output signal, selected from the group consisting of an acoustic output signal and an optical output signal, that is chronologically correlated with said sequence of images.
