Abstract: The invention provides a method for generating a non-invasive measure of blood vessel rigidity for a subject. The method includes obtaining 2D ultrasound data and 3D ultrasound data of the blood vessel from a given measurement location. The 2D ultrasound data provides information relating to a movement of the blood vessel and the 3D ultrasound data provides information relating to a shape of the blood vessel. A motion of the blood vessel is then determined based on the movement of the blood vessel. The method then includes providing the determined motion of the blood vessel, the shape of the blood vessel and an obtained non-invasive pressure measurement to a biomechanical model. A measure of rigidity is then determined based on the biomechanical model.

Abstract: A computer system is disclosed comprising a processor arrangement communicatively coupled to a data storage arrangement storing a digital model of a section of a lumen system of a patient; and a communication module communicatively coupled to said processor arrangement and arranged to receive sensor data pertaining to an internal parameter of said lumen system from a sensor within said section of the lumen system. The processor arrangement is arranged to receive said sensor data from the communication module; retrieve said digital model from the data storage arrangement;simulate an actual physical condition of said lumen system by developing said digital model based on the received sensor data; and generate an output relating to said simulated actual physical condition for updating an electronic device. Also disclosed is a method of monitoring a patient with such a computer system, a computer program product for implementing such a method and a patient monitoring system.

Abstract: A stress prediction device for predicting mechanical stress exerted to a deformable object due contact between the object and an external device that is to be inserted into the object at an intended insertion position comprises a segmentation unit configured to access generic model data representing a generic reference object that comprises predefined secondary landmark features at predefined landmark positions, which are not identifiable using a predefined imaging technique, and pre-insertion object image data acquired using the imaging technique. It provides segmented object model data which comprises associated mapped landmark position data indicative of mapped landmark positions of the secondary landmark features. A stress determination unit determines and provides predictive stress information indicative of mechanical stress exerted to at least one of the secondary landmark features at the associated mapped landmark position due to mechanical contact between the object and the external device.

Abstract: The invention relates to a navigation assistance system for assisting in navigating an interventional instrument (10) within a subject during an interventional procedure. Based on a provided current position and shape of the interventional instrument, a provided target position defining the position of a target (45) to which the interventional instrument is to be moved and provided configuration information being indicative of possible configurations of the interventional instrument a possible path (50) is determined, which allows the interventional instrument to reach the target. The determined possible path and preferentially also the current position and shape of the interventional instrument and the target position can be shown on a display in realtime, while a physician moves the interventional instrument, thereby assisting the physician in navigating the interventional instrument.
