Abstract: Ultrasound imaging systems and methods for generated clutter-reduced images are provided. For example, an ultrasound imaging system can include an array of acoustic elements in communication with a processor. The processor is configured to activate the array to perform a scan sequence to obtain a plurality of signals, identify off-axis signals from the plurality of signals by comparing the right subaperture and the left subaperture, and create a clutter-reduced image based on the comparison. Because off-axis signals are more likely to create image clutter, reducing the influence of off-axis signals on the image can therefore improve the quality of the image. Accordingly, embodiments of the present disclosure provide systems, methods, and devices for generating ultrasound images that have reduced or minimized clutter, even for images obtained using arrays that do not satisfy the Nyquist criterion.

Abstract: A MRS (magnetic resonance spectroscopy or nuclear magnetic resonance NMR)-based PTSD (post-traumatic stress disorder) and mTBI (mild traumatic brain injury) diagnostic system and method uses MRS signals, already pre-processed by the MRS scanner software. The signals are collected in vivo from specific regions of the brain.

These classifiers are identified through analysis of features of individuals whose health status is known. Once the classifiers are trained, patients can be diagnosed by using the same wavelet features extracted from in vivo MRS scans of their brain regions.

A reference set of R-peaks is identified in the reference ECG dataset based on the initial R-peak polarity and the initial R-R interval, and R-peak reference data is generated based on the reference set of R-peaks. Acquisition of MR image data from the subject is then triggered using the R-peak reference data.
