Abstract
Systems and methods for non-invasive assessment of an arterial stenosis, comprising include segmenting a plurality of mesh candidates for an anatomical model of an artery including a stenosis region of a patient from medical imaging data. A hemodynamic index for the stenosis region is computed in each of the plurality of mesh candidates. It is determined whether a variation among values of the hemodynamic index for the stenosis region in each of the plurality of mesh candidates is significant with respect to a threshold associated with a clinical decision regarding the stenosis region.
Claims28
A method for non-invasive assessment of an arterial stenosis, comprising:
- segmenting a plurality of mesh candidates for an anatomical model of an artery including a stenosis region of a patient from medical imaging data;
- computing a hemodynamic index for the stenosis region in each of the plurality of mesh candidates;
- and
- determining whether a variation among values of the hemodynamic index for the stenosis region in each of the plurality of mesh candidates is significant with respect to a threshold associated with a clinical decision regarding the stenosis region.
An apparatus for non-invasive assessment of an arterial stenosis, comprising:
- means for segmenting a plurality of mesh candidates for an anatomical model of an artery including a stenosis region of a patient from medical imaging data;
- means for computing a hemodynamic index for the stenosis region in each of the plurality of mesh candidates;
- and
- means for determining whether a variation among values of the hemodynamic index for the stenosis region in each of the plurality of mesh candidates is significant with respect to a threshold associated with a clinical decision regarding the stenosis region.
A non-transitory computer readable medium storing computer program instructions for non-invasive assessment of an arterial stenosis, the computer program instructions when executed by a processor cause the processor to perform operations comprising:
- segmenting a plurality of mesh candidates for an anatomical model of an artery including a stenosis region of a patient from medical imaging data;
- computing a hemodynamic index for the stenosis region in each of the plurality of mesh candidates;
- and
- determining whether a variation among values of the hemodynamic index for the stenosis region in each of the plurality of mesh candidates is significant with respect to a threshold associated with a clinical decision regarding the stenosis region.
A method for supporting a clinical decision regarding an anatomical object of interest, comprising:
- segmenting a plurality of mesh candidates for an anatomical model of an anatomical object of interest of a patient from medical imaging data;
- computing a quantitative metric for each of the plurality of mesh candidates;
- and
- determining whether a variation among values of the quantitative metric for each of the plurality of mesh candidates is significant regarding with respect to a threshold associated with a clinical decision regarding the anatomical object of interest.
