Abstract:
Many medical procedures involve the implantation of an element in a vascular body. Current imaging techniques allow the positioning of such expandable elements to be checked, before and after implantation, using contrast bursts into the blood from a pigtail catheter. When the implantation of the medical device needs to be performed quickly, the pigtail catheter is pulled back briskly. This process is prone to error, because at the point of implantation, a medical professional has many other factors to consider, as well as the withdrawal of the catheter. If an implantable device traps the pigtail catheter during or after expansion, undesirable results can occur, such as having to pull sharply on the catheter to remove it, and in the process, disrupting the newly implanted device. This application discusses a technique for automatically generating a region of implantation around a medical device prior to and during implantation. If a second medical device, such as a pigtail catheter, strays into the area, an alarm can be generated to warn a medical professional to withdraw the catheter, before deployment continues.

Claim (Index 11):
A method for generating a medical device implantation warning, comprising the steps of:\n a) providing an X-ray image sequence comprising a plurality of X-ray frames of a region of interest of an object; b) generating a spatial implantation envelope of a first medical device to be deployed in a region of implantation, wherein the spatial implantation envelope defines a spatial extent of the region of implantation during and/or after a deployment of the first medical device, c) detecting, in the first X-ray frame, image data representing a second medical device located at a second medical device position inside the region of interest; d) detecting a potential intersection condition of the spatial implantation envelope and the second medical device position; e) generating the device implantation warning if the potential intersection condition between the spatial implantation envelope and the second medical device position is detected in step d).
