Real-time feedback and semantic-rich guidance on quality ultrasound image acquisition
A method for providing real-time feedback and semantic-rich guidance on ultrasound image quality is performed by a processor in an ultrasound system. The method includes receiving an ultrasound image and classifying the ultrasound image into one or more categories based on image features. The classifying creates a classified image. The method also includes determining whether the classified image provides an acceptable representation of a target organ. In response to determining that the classified image does not provide an acceptable representation of the target organ, the method includes selecting operator guidance corresponding to the one or more category; presenting via a display and/or audible sound, the selected operator guidance; and receiving additional ultrasound images. The method further includes calculating a result based on the classified image in response to determining that the classified image provides an acceptable representation of the target organ.
Shape-based generative adversarial network for segmentation in medical imaging
For segmentation in medical imaging, a shape generative adversarial network (shape GAN) is used in training. By including shape information in a lower dimensional space than the pixels or voxels of the image space, the network may be trained with a shape loss or optimization. The adversarial loss and the shape loss are used to train the network, so the resulting generator may segment complex shapes in 2D or 3D. Other optimization may be used, such as using a loss in image space.
Labeling medical scans via prompt decision trees
A method comprises displaying, via an interactive interface, a medical scan and a plurality of prompts of each prompt decision tree of a plurality of prompt decision trees in succession, beginning with automatically determined starting prompts of each prompt decision tree, in accordance with corresponding nodes of each prompt decision tree until a leaf node of each prompt decision tree is ultimately selected. Labeling data indicating the ultimately selected leaf node of each prompt decision tree is determined for the medical scan.
SYSTEM AND METHOD FOR ULTRASOUND ANALYSIS
An exemplary system, method and computer-accessible medium for detecting an anomaly(ies) in an anatomical structure(s) of a patient(s) includes receiving imaging information related to the anatomical structure(s) of the patient(s), classifying a feature(s) of the anatomical structure(s) based on the imaging information using a neural network (s), and detecting the anomaly(ies) based on data generated using the classification procedure.
Quality indicators for collection of and automated measurement on ultrasound images
Aspects of the technology described herein relate to techniques for calculating, during imaging, a quality of a sequence of images collected during the imaging. Calculating the quality of the sequence of images may include calculating a probability that a medical professional would use a given image for clinical evaluation and a confidence that an automated analysis segmentation performed on the given image is correct. Techniques described herein also include receiving a trigger to perform an automatic measurement on a sequence of images, calculating a quality of the sequence of images, determining whether the quality of the sequence of images exceeds a threshold quality, and performing the automatic measurement on the sequence of images based on determining that the quality of the sequence of images exceeds the threshold quality.
