Problems solved by technology

[0005] Despite these benefits, routine flow measurement to assess additional hemodynamic properties has not yet entered clinical practice due to the added complexity and lack of robustness of any measurement technique that can be used to measure flow-related parameters

Embodiment Construction

[0115] The illustrations in the figures are schematic. In different figures, similar or identical elements bear the same reference signs.

[0116] figure 1 An exemplary embodiment of a device 1 for assessing hemodynamic properties is schematically represented. The device 1 includes an input unit 100 , a recognition unit 200 , a calculation unit 300 , a modeling unit 400 and a display unit 500 .

[0117] The input unit 100 receives a diagnostic image 10 of a vessel of interest. in accordance with figure 1 In the exemplary embodiment of the present invention, the diagnostic image 10 is a two-dimensional image acquired using X-ray angiography. The input unit 100 provides the diagnostic image 10 to the recognition unit 200 .

[0118] The recognition unit 200 is configured to receive the diagnostic image 10 and perform vessel segmentation of the vessel of interest represented in the diagnostic image 10, i.e. the recognition unit 200 segments the (image of) the vessel of intere...

Abstract

An apparatus for assessing a hemodynamic property in a coronary vasculature and a corresponding method are provided in which diagnostic data of a vessel of interest is used to identify a first and second measurement position at which a first and a second value for a first hemodynamic property may be obtained whereby these first and second values are suitable to derive at least one diagnostic parameter indicative of a second hemodynamic 5 property that cannot or should not be measured directly.

Description

technical field [0001] The invention relates to a device for assessing hemodynamic properties in the coronary vasculature, a corresponding method and a corresponding computer program. In particular, the present invention relates to improved measurement guidance for performing measurements of hemodynamic parameters by deriving from diagnostic data of the vasculature optimal measurement positions for intravascular measurements. Background technique [0002] The severity of functional stenosis in coronary arteries can usually be assessed by means of intravascular pressure measurements. In this regard, one can in particular consider the pressure at the distal end of the stenosis (P d ) and the pressure in the aorta (P a ) to perform the evaluation. Thus, this ratio can be taken into account using metrics such as Fractional Flow Reserve (FFR) or Instantaneous Wave-Free Ratio (iFR), both of which are determined from said pressure ratio. FFR measurements use pressure curves thr...
