Abstract
An apparatus and a method for assessing a vasculature is provided in which a time series of diagnostic images is used in combination with at least one boundary parameter associated with said time series to determine a quantitative fluid dynamics parameter indicative of the fluid flow through the vasculature using a trained classifier. By providing both, the time series of diagnostic images and the at least one boundary parameter to the determination, it is ensured that the classifier is provided with consistent data allowing for a more accurate determination of the quantitative fluid dynamics parameter.
Claims15
An apparatus for assessing a vasculature, comprising:
- an input unit configured to receive
- a time series of diagnostic images of the vasculature, and
- at least one boundary parameter associated with said time series of diagnostic images;
- a computation unit comprising a trained classifier device, the computation unit configured to generate a combination result based on the time series of diagnostic images and the at least one boundary parameter, and
- determine, using the trained classifier device, a quantitative fluid dynamics parameter indicative of the fluid flow through the vasculature based on the combination result.
A method for assessing a vasculature, comprising the steps of
- receiving a time series of diagnostic images of the vasculature,
- receiving at least one boundary parameter associated with said time series of diagnostic images,
- generating a combination result based on the time series of diagnostic images and the at least one boundary parameter, and
- determining, using a trained classifier device, a quantitative fluid dynamics parameter indicative of the fluid flow through the vasculature based on the combination result.
