PAE treatment for BPH

A non-transitory computer readable storage medium having stored therein data representing instructions executable by a programmed processor for guiding a catheter during an embolization operation for a lesion, the instructions comprising computer code to:

• receive volume data of a patient volume, the patient volume including the lesion and a feeding vessel for the lesion;
• determine a margin boundary extended outward a distance from a boundary of the lesion to define a margin around the lesion in the volume data;
• detect the feeding vessel in the volume data;
• define a vessel connection path for the feeding vessel, the vessel connection path connecting first and second points in the volume data, the first point being disposed along an artery for the feeding vessel and the second point being disposed along the feeding vessel within the margin boundary;
• receive, via an x-ray imaging system, fluoroscopic projection data of the patient volume and the catheter, the fluoroscopic projection data being generated by the x-ray imaging system;
• and
• render an image from the fluoroscopic projection data of the patient volume and the catheter during the embolization operation, the image additionally comprising the vessel connection paths for the feeding vessel;
• wherein the computer code to detect the feeding vessel is configured to detect the second point via analysis of the volume data.

A system for guiding a catheter during an embolization operation for a lesion, the system comprising:

• a memory in which volume data of a patient volume is stored;
• an x-ray imaging system operable to generate fluoroscopic projection data for the patient volume and the catheter;
• a processor configured to define a vessel connection path for a feeding vessel for the lesion and to render a representation of the patient volume and the catheter via the fluoroscopic projection data, the representation comprising the vessel connection path;
• and
• a display operable to display the representation during the embolization operation;
• wherein the processor is further configured to determine a margin boundary extended outward a distance from a boundary of the lesion to define a margin around the lesion in the volume data, and to detect the feeding vessel in the volume data, the vessel connection path connecting first and second points in the volume data, the first point being disposed along an artery for the feeding vessel and the second point being disposed along the feeding vessel within the margin boundary;
• wherein the processor is configured to detect the second point in the volume data via analysis of the volume data.
