Computer-implemented method for determination of a bone cement volume of a bone cement for a percutaneous vertebroplasty

A computer-implemented method for determination of a bone cement volume of a bone cement for a percutaneous vertebroplasty, the method comprising:

• receiving data about a bone structure of a bone section;
• determining a bone density distribution of the bone section depending on the data;
• determining a bone space in the bone section depending on the bone density distribution, wherein a bone density of the bone space is less than a predetermined density threshold value;
• determining a bone space volume of the bone space;
• virtually filling at least part of the bone space with a first volume of the bone cement;
• determining a bone strength of the bone space filled virtually with the first volume of the bone cement;
• determining and outputting the bone cement volume depending on the bone space volume, the bone strength, or both the bone space volume and the bone strength;
• and
• determining a risk of a leakage of the bone cement from the bone space beforehand, wherein the determining of the risk comprises:
• identifying a hole in a cortical shell of the bone section that is located closer than a predetermined first distance to the bone space or is connected to the bone space;
• and/or
• identifying a region in the cortical shell with a thickness below a predetermined minimum thickness, wherein the region is located closer than a predetermined second distance from the bone space;
• and/or
• determining a third distance from the bone space to a plexus venosus posterior.

A system for data processing, the system comprising:

• at least one processor configured to:
• receive data about a bone structure of a bone section;
• determine a bone density distribution of the bone section depending on the data;
• determine a bone space in the bone section depending on the bone density distribution, wherein a bone density of the bone space is less than a predetermined density threshold value;
• determine a bone space volume of the bone space;
• virtually fill at least part of the bone space with a first volume of a bone cement;
• determine a bone strength of the bone space filled virtually with the first volume of the bone cement;
• and
• determine and output a bone cement volume depending on the bone strength.
