The systems can communicate directly, indirectly, and/or wirelessly. Each can also be configured for cross-imaging in the other modality, displaying medical imagery from the other modality on respective and/or combined displays, and/or control by a user interface of the other and/or a common user interface. Registry between patient imagery is possible, and improved workflow is provided.

Medical imaging system and method containing ultrasound docking port

A method is disclosed, in a diagnostic medical environment, that enhances workflow while using a computer-aided-detection (or diagnosis) (CAD) system in the environment. The method comprises generating image data with a diagnostic medical imaging acquisition system. The image data is transmitted from the diagnostic medical imaging acquisition system to a computer-aided-detection (or diagnosis) (CAD) system and an archive/review station. Detection results are generated by processing the image data, using the CAD system, while storing and viewing the image data on the archive/review station. The detection results are transmitted from the CAD system to the archive/review station. The detection results are integrated with the image data by the archive/review station to form composite image data. The composite image data is displayed by the archive/review system.

A method includes obtaining a first image of a subject at a first position, changing a position between the detector and the subject, obtaining a second image, and pasting the first and images to obtain a composite image. The first image and the second image may have an amount of overlap equal to no more than about 30 percent of a field of view of the detector in a direction of movement between the first image and the second image, and, according to some embodiments, may have an overlap of about 4 percent to about 16 percent. This may, in some embodiments, amount to an amount of overlap of about 1.5 cm to about 6.5 or 12 cm. In some embodiments, the span of overlap of the images is at least about 30 cm. The geometry of the images may be used to help paste the images together appropriately.
