Abstract: The present disclosure provides for improved image analysis via novel deblurring and segmentation techniques of image data. These techniques advantageously account for and incorporate segmentation of biological analytes into a deblurring process for an image. Thus, the deblurring of the image may advantageously be optimized for enabling identification and quantitative analysis of one or more biological analytes based on underlying biological models for those analytes. The techniques described herein provide for significant improvements in the image deblurring and segmentation process which reduces signal noise and improves the accuracy of the image. In particular, the system and methods described herein advantageously utilize unique optimization and tissue characteristics image models which are informed by the underlying biology being analyzed, (for example by a biological model for the analytes). This provides for targeted deblurring and segmentation which is optimized for the applied image analytics.

Abstract: For measurement point determination in imaging with a medical scanner, the user selects a location on the image. Rather than using that location, an “intended” location corresponding to a local boundary or landmark represented in the image is identified. The medical scanner uses the simple user interface to more exactly determine points for measurement. One or more rays are cast from the user selected location. The actual location is found by examining data along the ray or rays. For 2D imaging, the rays are cast in the plane. For 3D imaging, the ray is cast along a view direction to find the depth. The intensities along the ray or around the ray are used to find the actual location, such as by application of a machine-learnt classifier to the limited region around the ray or by finding intensities along the ray relative to a threshold.

Abstract: 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.
