Fusion of parametric images by magnetic resonance and ultrasound

Parametric images by magnetic resonance and ultrasound are merged or combined. MRI and ultrasound imaging is used to acquire (30, 32) the same type of parametric images. The merged data are created (44) by combining ultrasound and MRI parametric data at instants which both types of data are available. Rather than sacrificing throughput, the merged data is created (44) for moments which MRI data is not acquired. A curve representing the parameter values ​​in time is adjusted on MRI and ultrasound data available for each location, resulting in merged data at instants which MRI data is not available.
