Abstract
A user interface (GUI) to help operator position a catheter (DC) or other medical devices during a denervation procedure or similar interventions in or around an organ. A virtual gauge (DR) is shown overlaid on an X-ray projection image (IM) or other digital image to so allow an operator read off length information. The orientation of the virtual gauge (DR) is automatically or by user interaction aligned with an orientation of the organ or device (DC).
Claims15
An apparatus for supporting medical device positioning, comprising:
- an input port for receiving an X-ray projection image of an object acquired by an imager;
- a user interface generator configured to generate for display on a screen a virtual gauge Overlaid on the image so as to enable a user to read off length information in relation to the object and/or a medical device residing in or around said object;
- wherein the user interface generator is configured to automatically scale the graduation on the gauge based on an imagining geometry setting of the imager used when acquiring the X-ray projection image of the object.
A method of supporting medical device positioning, comprising the steps of:
- receiving an X-ray projection image of an object and/or a medical device that resides in or around said object;
- automatically aligning and overlaying on said image for display a virtual gauge, a direction of said virtual gauge thereby aligned:
- i) with an orientation of the medical device;
- and/or
- ii) with an orientation of the object;
- and
- re-aligning said direction upon detecting a change in the object or device orientation.
