Systems and method for performing particle-based simulation of fluid flow

A computer-implemented method for vascular assessment, comprising:

• generating, via one or more processors, a model of at least a portion of a targeted vessel, the model based on a plurality of representations of at least one vascular segment included in the targeted vessel, the representations based on a plurality of medical images acquired prior to application of a stenosis treatment to the targeted vessel;
• determining, via the one or more processors, an index indicative of vascular function of the targeted vessel using the model;
• receiving, via the one or more processors, at least one post-procedure medical image of the targeted vessel, the at least one post-procedure medical image depicting at least one treated vascular segment of a treated vessel that includes the targeted vessel that has been subjected to the stenosis treatment;
• updating, via the one or more processors, the model based on an at least partial update of the at least one vascular segment with the at least one treated vascular segment;
• and
• determining, via the one or more processors, an updated index indicative of vascular function for the treated vessel based on the updated model.

A system for vascular assessment, comprising:

• at least one memory storing instructions;
• and
• at least one processor operatively connected to the memory and configured to execute the instructions to perform operations, including:
• generating, a model of at least a portion of a targeted vessel, the model based on a plurality of representations of at least one vascular segment included in the targeted vessel, the representations based on a plurality of medical images acquired prior to application of a stenosis treatment to the targeted vessel;
• determining an index indicative of vascular function of the targeted vessel using the model;
• receiving at least one post-procedure medical image of the targeted vessel, the at least one post-procedure medical image depicting at least one treated vascular segment of a treated vessel that includes the targeted vessel that has been subjected to the stenosis treatment;
• updating the model based on an at least partial update of the at least one vascular segment with the at least one treated vascular segment;
• and
• determining an updated index indicative of vascular function for the treated vessel based on the updated model.

A non-transitory computer-readable medium comprising instructions for vascular assessment that are executable by at least one processor to cause the at least one processor to perform operations, including:

• generating, a model of at least a portion of a targeted vessel, the model based on a plurality of representations of at least one vascular segment included in the targeted vessel, the representations based on a plurality of medical images acquired prior to application of a stenosis treatment to the targeted vessel;
• determining an index indicative of vascular function of the targeted vessel using the model;
• receiving at least one post-procedure medical image of the targeted vessel, the at least one post-procedure medical image depicting at least one treated vascular segment of a treated vessel that includes the targeted vessel that has been subjected to the stenosis treatment;
• updating the model based on an at least partial update of the at least one vascular segment with the at least one treated vascular segment;
• and
• determining an updated index indicative of vascular function for the treated vessel based on the updated model.
