Abstract: Measurements in diagnostic medical imaging are cross-referenced. A measurement made for one type of data is reflected in an image for another type of data. For example, a length is measured from ultrasound data. A line associated with the length is displayed on the ultrasound image. In a magnetic resonance image (MRI), the same line is displayed at a corresponding location. The same measurement may also be made with the MRI data and reflected in the ultrasound image. Each image shows both measurements in this example. The difference in the same measurements from different types of data may be useful for diagnosis. In the above example, the length is measured from ultrasound and from MRI. The difference between the two measured lengths may provide diagnostically useful information.

Abstract: Free-hand manual navigation assists diagnosis using perspective rendering for three or four dimensional imaging. In addition to a three-dimensional rendering for navigation, a number of two-dimensional images corresponding to a virtual camera location are displayed to assist the navigation and visualization. Alternatively or additionally, a representation of the virtual camera is displayed in one or more two-dimensional images. The virtual camera is moved within the two-dimensional images to navigate for perspective rendering.

Abstract: Without using ECG input signals or processor intensive correlation, cyclical timing is determined from ultrasound data. Cyclical timing includes determining the time of end diastole, time of end systole or heart rate. The ultrasound data is reduced, such as by projecting each frame of data onto two axes. For projection, data is summed along each dimension. The location associated with the maximum variance through the sequence is identified from the projected data. The ultrasound data associated with the location is used to identify cycle timing information, such as to provide a waveform representing the cycle. Lines from different frames of data in the sequence are also used to generate an image. The image shows cycle timing information.

Abstract: Medical diagnostic ultrasound stereo imaging is provided. A medical diagnostic ultrasound system operable to scan a body with ultrasound is also operable to generate a three dimensional stereoscopic view of the body. The video processing unit and/or display device create the stereoscopic display.
