A method for determining at least one property of an object, the method comprising a step of: - determining the at least one property of the object based on first data and second data, the first data being the movement of the object obtained by imaging the object according to a first imaging modality, the first imaging modality being an ultrasound imaging technique imaging the object at a frame rate superior to 300 Hz, at least one of the following properties being fulfilled for the first imaging modality: - the first imaging modality being adapted to apply unfocused ultrasound waves, - the first imaging modality being adapted to apply multiple ultrasound plane waves simultaneously, and - the ultrasound imaging technique is chosen in the group consisting of functional ultrasound imaging, electromechanical wave imaging, shear-wave imaging, three-dimensional ultrafast ultrasound imaging, and four-dimensional ultrafast ultrasound imaging, the second data being data relative to the object obtained by imaging the object according to a second imaging modality based on the detection of rays, each detected ray being a X-ray or a γ-ray, the step of determining comprising correcting the images obtained by the second imaging modality based on the first data, to obtain reconstructed images, wherein the first imaging modality is carried with an ultrasound probe which is held by a support. - determining the at least one property of the object based on first data and second data, the first data being the movement of the object obtained by imaging the object according to a first imaging modality, the first imaging modality being an ultrasound imaging technique imaging the object at a frame rate superior to 300 Hz, at least one of the following properties being fulfilled for the first imaging modality: - the first imaging modality being adapted to apply unfocused ultrasound waves, - the first imaging modality being adapted to apply multiple ultrasound plane waves simultaneously, and - the ultrasound imaging technique is chosen in the group consisting of functional ultrasound imaging, electromechanical wave imaging, shear-wave imaging, three-dimensional ultrafast ultrasound imaging, and four-dimensional ultrafast ultrasound imaging, the second data being data relative to the object obtained by imaging the object according to a second imaging modality based on the detection of rays, each detected ray being a X-ray or a γ-ray, the step of determining comprising correcting the images obtained by the second imaging modality based on the first data, to obtain reconstructed images, wherein the first imaging modality is carried with an ultrasound probe which is held by a support. the first data being the movement of the object obtained by imaging the object according to a first imaging modality, the first imaging modality being an ultrasound imaging technique imaging the object at a frame rate superior to 300 Hz, at least one of the following properties being fulfilled for the first imaging modality: - the first imaging modality being adapted to apply unfocused ultrasound waves, - the first imaging modality being adapted to apply multiple ultrasound plane waves simultaneously, and - the ultrasound imaging technique is chosen in the group consisting of functional ultrasound imaging, electromechanical wave imaging, shear-wave imaging, three-dimensional ultrafast ultrasound imaging, and four-dimensional ultrafast ultrasound imaging, - the first imaging modality being adapted to apply unfocused ultrasound waves, - the first imaging modality being adapted to apply multiple ultrasound plane waves simultaneously, and - the ultrasound imaging technique is chosen in the group consisting of functional ultrasound imaging, electromechanical wave imaging, shear-wave imaging, three-dimensional ultrafast ultrasound imaging, and four-dimensional ultrafast ultrasound imaging, the second data being data relative to the object obtained by imaging the object according to a second imaging modality based on the detection of rays, each detected ray being a X-ray or a γ-ray, the step of determining comprising correcting the images obtained by the second imaging modality based on the first data, to obtain reconstructed images, wherein the first imaging modality is carried with an ultrasound probe which is held by a support.
