Abstract: A three-dimensional (3D) optical coherence tomography angiography (OCTA) method and system based on feature space is provided. OCT signals of scattering samples in a 3D space are acquired by a collector; a theoretical classifier, local signal-noise ratios (SNRs) and decorrelation coefficients of the OCT scattering signals are combined to establish a two-dimensional (2D) feature space to realize classification of dynamic blood flow signals and static tissues. Specifically, computational analysis of first-order and zero-order autocovariance is used to obtain two features of SNR and decorrelation of each OCT scattering signal; a 2D inverse SNR (iSNR)-decorrelation feature (ID) space is established; and based on the multivariate time series theory, a linear classifier is established in the ID space to remove a static surrounding tissue background. The 3D OCTA method and system can improve the contrast of blood flow images and-improve the accuracy of blood flow quantification.

Abstract: During acquisition of an ultrasound image feed, ultrasound control data frames are acquired that may be interspersed amongst the ultrasound data frames. The control data frames may use consistent reference scan parameters, irrespective of the scanner settings, and may not need to be converted to image frames. The control data frames can be passed to an artificial intelligence model, which predicts the suitable settings for scanning the anatomy that is being scanned. The artificial intelligence model can be trained with a dataset containing different classes of ultrasound control data frames for different settings, where substantially all the ultrasound control data frames in the dataset are consistently acquired using the reference scan parameters.

Abstract: Machine learning trains to tune settings. For training, the user interactions with the image parameters (i.e., settings) as part of ongoing examination of patients are used to establish the ground truth positive and negative examples of settings instead of relying on an expert review of collected samples. Patient information, location information, and/or user information may also be included in the training data so that the network is trained to provide settings for different situations based on the included information. During application, the patient is imaged. The initial or subsequent image is input with other information (e.g., patient, user, and/or location information) to the machine-trained network to output settings to be used for improved imaging in the situation.
