Abstract: An ultrasound system and method enable ultrasonic imaging by inexperienced personnel under the guidance of a remotely located diagnostic imaging expert. Improper use of the scanning device is prevented by controlling the device to present only low quality images to the person conducting the scan, while images of high quality are sent to the remote expert for diagnosis. Thus, an effective diagnosis by the expert is facilitated while providing at the scanning site only images which, while sufficient to provide visual guidance of the scanning procedure, cannot be used improperly by persons at the site of the patient being scanned.

Abstract: Extracorporeal motion (130) relative to a medical subject being imaged is detected, through the imaging or from motion detectors on the imaging probe, and either backed out of the medical images so that it can be determined whether lung sliding exists or measured to determine whether lung sliding detection is to be suspended due to excessive extracorporeal motion. Image sub-regions (164, 168) corresponding to respective ones of the images are selected for image-to-image comparison such that the selected sub-regions contain only body tissue that is, with respect to imaging depth in the acquiring of the images, shallower than an anatomical landmark within the images. Based on a result of the comparing, lung sliding detection that entails examining image data deeper than the landmark may be initialized.

Abstract: A medical imaging probe (102) for contact with an imaging subject includes an indicium placement apparatus for, while the probe is in contact, selectively performing an instance of marking the subject so as to record a position of the probe. The device may further include a feedback module for determining whether an orientation, with respect to a the mark, that currently exists for a medical imaging probe of the device meets a criterion of proximity to a predetermined orientation. Responsive to the determination that the criterion is met, a quantitative evaluation may be made automatically and without need for user intervention, via live imaging via the probe, of a lesion that was, prior to the determination, specifically identified for the evaluation. Change, such as growth (116), in the lesion, like a brain lesion, may thereby be tracked over consistent sequential imaging acquisitions, such as through ultrasound.
