An image-based user interface is used for controlling medical imaging. A variety of images of a same region but associated with different settings are displayed to the user. The user selects the desired image. The medical imager is then configured with the settings from the selected image for imaging a patient.

Image-based user interface for controlling medical imaging

To reduce speckle is spectral Doppler imaging, any oversampling relative to the velocity scale is used to create different data sets for the location at a given time. The different data sets have at least partially independent noise. Spectra are estimated from the different data sets and the resulting spectra combined into a spectrum with less speckle. To improve signal-to-noise ratio, the samples acquired for a given velocity scale are band-limited into different narrower bands. The portion of the spectrum estimated for each narrow band has a higher signal-to-noise ratio than a spectrum estimated for the entire band. The parts of the spectrum estimated for the different narrow bands are stitched together to provide a spectrum for the entire band with greater signal-to-noise ratio. In another approach, the user may input a narrow band relative to the velocity scale so that the corresponding part of the spectrum is provided with greater signal-to-noise ratio. Similar approaches may be used for color or flow imaging.

Doppler imaging

Gap filling is provided in spectral Doppler ultrasound. Due to the cyclical nature of the cardiac system, data likely to be similar to data that would have been acquired without interleaving is copied into the gap generated by interleaving. Acquired data associated with the gap, such as adjacent to the gap, is correlated with other acquired data. By identifying similar data, acquired data temporally related to the similar data as the gap associated data is temporally related to the gap is found. This found data is likely to be similar to data that would have been acquired during the gap. The gap is filled with a copy of this data.
