Abstract
The detection of a distal end of a medical instrument in a surrounding region may be made with as little contrast medium as possible. For this purpose, a contrast medium is ejected at the distal end of the medical instrument into the surrounding region. The ejected contrast medium is determined automatically with an imaging modality in the surrounding region. The ejection of the contrast medium is then automatically reduced or terminated depending on the result of the detection.
Claims15
A method for detecting a contrast medium in a region surrounding an outlet of a medical instrument, the method comprising:
- ejecting a contrast medium at a distal end of the medical instrument into the surrounding region;
- automatically detecting the ejected contrast medium with an imaging modality in the surrounding region;
- and
- automatically reducing or terminating the ejection of the contrast medium depending on a result of the detection.
A system comprising:
- a medical instrument having an outlet for ejecting a predetermined contrast medium;
- an imaging modality configured to detect a portion of the predetermined contrast medium ejected at the outlet of the medical instrument;
- and
- a control facility configured to reduce or terminate an ejection of the predetermined contrast medium depending on a result of the detection.
A computer program comprising instructions that, when executed by a system having a medical instrument, imaging modality, and control facility, cause the system to:
- eject a contrast medium at a distal end of the medical instrument into a region surrounding the distal end of the medical instrument;
- automatically detect the ejected contrast medium with the imaging modality in the surrounding region;
- and
- automatically reduce or terminate the ejection of the contrast medium by the control facility depending on a result of the detection.
