Abstract: An ultrasound system performs duplex colorflow and spectral Doppler imaging, with the spectral Doppler interrogation performed at a sample volume location shown on the colorflow image. The colorflow image is displayed in a color box overlaid on a co-registered B mode image. A color box position and steering angle processor analyzes the spatial Doppler data and automatically sets the color box angle and location over a blood vessel for optimal Doppler sensitivity and accuracy. The processor may also automatically set the flow angle correction cursor in alignment with the direction of flow. In a preferred embodiment these optimization adjustments are made automatically and continuously as a user pauses at points for Doppler measurements along a length of the blood vessel.

Abstract: A nuclear camera acquires projections which are iteratively reconstructed by a reconstruction processor into an motion-artifacted image and stored in an image memory. The motion-artifacted image is forward-projected by a forward-projector to create forward-projections which are compensated for image degrading factors, such as resolution recovery, scatter and attenuation, and are compared with the acquired projections by a comparing unit to generate a motion-correction. A motion compensator operates on the acquired projections with the motion-correction to generate a motion-corrected projection data set in which each of the projections is in a common motion state. The motion-corrected projections are reconstructed into a motion-corrected image.
