1. 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.
