Abstract
The invention is directed to a method of determining properties in a vessel or the heart (V) of a patient. It comprises the steps of placing an element in a vessel or the heart(V) and determining a propulsion force (2) acting on the element. Furthermore, at least one of acceleration (3) and velocity (4) of the element is determined. At least one property of a neighbouring medium of the element is determined based on the propulsion force and at least one of acceleration (3) and velocity (4) of the element.

A system for determining properties in a vessel or a heart of a patient, comprising:
- a magnetic element to be placed in the vessel or the heart and adapted for being actuated by a magnetic field,
- means for determining a magnetic propulsion force acting on the magnetic element when actuated by the magnetic field,
- an imaging device adapted for imaging an area surrounding the magnetic element and allowing to determine the location of the magnetic element with respect to the anatomy,
- means for determining at least one of an effective acceleration and effective velocity based on imaging data obtained by the imaging device,
- means for determining at least one property of a tissue of the magnetic element, based on a difference between a theoretical acceleration or terminal velocity calculated determined based on the magnetic propulsion force, and at least one of the effective acceleration and the effective velocity of the magnetic element,
- the property being selected from an elasticity, stiffness, ductility, and hardness.
