US Patent 8942342 Multi-modality image acquisition

The techniques described herein provide a means for generating an x-ray image and ultrasound image depicting parallel planes of an object under examination and may be used in conjunctions with x-ray or ultrasound techniques known to those in the field (e.g., x-ray tomosynthesis, computed tomography ultrasound imaging, etc.). In one example, one or more x-ray images are spatially coincident to one or more ultrasound images and the images may be combined through spatial registration. It finds particular application to mammography examinations but may be used in other fields that use information from multiple modalities.
