1. A method for multi-modality medical imaging fusion, the method comprising:

  • acquiring scan data representing a region of the patient, the scan data being of a modality other than ultrasound, the modality other than ultrasound comprising x-ray, angiography, single photo emission computed tomography, positron emission tomography, magnetic resonance, or computed tomography;

    scanning at least a first part of the region of the patient with a first ultrasound transducer comprising a first probe, the scanning providing first ultrasound data;

    detecting, with a sensor, a first position of the first ultrasound transducer during the scanning with the first ultrasound transducer;

    spatially registering the first ultrasound data with the scan data, the spatially registering providing a spatial transform relating a first coordinate system of the first probe with a scan data coordinate system of the scan data;

    scanning at least a second part of the region of the patient with a second ultrasound transducer comprising a second probe, the scanning providing second ultrasound data;

    detecting, with the sensor or another sensor, a second position of the second ultrasound transducer during the scanning with the second ultrasound transducer;

    spatially aligning the second ultrasound data from the second ultrasound transducer with the scan data of the modality other than ultrasound, the spatially aligning relating a second coordinate system of the second probe to the scan data coordinate system, the spatially aligning being an adjustment of the spatial transform from a difference between the first and second positions of the first and second ultrasound transducers and application of the adjusted spatial transform between the scan data and the second ultrasound data so that locations in the patient represented in the second scan data are known in the scan data; and

    generating a multi-modality fusion image from the scan data and the second ultrasound data, the multi-modality fusion image being a function of the spatially aligning, the multi-modality fusion image comprising the scan data as x-ray, angiography, single photo emission computed tomography, positron emission tomography, magnetic resonance, or computed tomography data fused with the second ultrasound data.
