The invention relates to assisting a user in moving an insertion element within an object. A three-dimensional (3D) position and 3D local shape of the insertion element are tracked within the object. Based on the tracked 3D position and 3D local shape of the insertion element, an insertion element representation ('″) representing the insertion element within the object in its 3D position and 3D local shape is generated. Furthermore at least two different markings () applied along the length of the insertion element representation (′″) representing indications of the local shape of the insertion element are provided. A display image (″) including the insertion element representation (′″) with the different markings () is displayed. Markings can for example include alternating ring-like structures () with alternating lighter and darker colors and/or different colors for the tip and the rest of the insertion element representation for improving 3D visualization of insertion elements.

Assisting in moving an insertion element within an object

An apparatus for determining a functional index for stenosis assessment of a vessel is provided. The apparatus comprises an input interface () and a processing unit (). The input interface is configured to obtain image data () representing a two-dimensional representation of a vessel (). The processing unit () is configured to determine a course of the vessel () and a width (w, w) of the vessel along its course in the image data and is further configured to determine the functional index for stenosis assessment of the vessel based on the width of the vessel in the image data.

Apparatus for determining a functional index for stenosis assessment

Systems and related methods to estimate, for a liquid dynamic system, flow or resistance based on a model of an object and pressure measurements collected in-situ at said object. Alternatively, pressure flow measurements are collected and pressure or resistance is being estimated.

Estimating flow, resistance or pressure from pressure or flow measurements and angiography

Disclosed are an imaging system () or an interventional tool, such as a catheter (), having a first ultrasound transducer array () and a second ultrasound transducer array () spaced by a fixed distance (D) from each other; wherein both arrays may be used to generate diagnostic images; and a processing arrangement () to process a first sensor signal indicative of the first array imaging a reference location (X) at a first point in time, and to process a second sensor signal indicative of the second array imaging the reference location at a second point in time; and determine a translation (pullback) speed of the catheter from the set distance and the difference between the first point in time and the second point in time. Alternatively, a catheter may be provided comprising an ultrasound transducer array at a distal end of the catheter, and two pressure sensors for determining the translation speed.

Imaging system and method of determining a translation speed of a catheter

The invention relates to an assistance device, an assistance system and an assistance method for assisting a practitioner in an interventional hemodynamic (e.g fractional flow reserve (FFR)) measurement on a subject. The FFR pressure measurements are combined with an, for example, angiography-based assessment of the coronary vessel geometry. An advanced computational fluid dynamics model may be employed to add flow and myocardial resistance data based on the interventional pressure values and on a vascular model generated prior to the intervention. In case that these data are available prior to the intervention, the location of most optimal positions for pressure measurements can be pre-calculated and by overlay of the vessel tree, for example, on the X-ray projection, advice can be given for the interventional cardiologist during the intervention.
