Non-invasive measurement of intracranial pressure (ICP), for example mean ICP. A probe adjacent the head emits energy, such as ultrasound, and receives reflected signals. A processing unit derives ICP waveform from the signals. A pressure mechanism applies external pressure intermittently to outer surface of the head and incrementally increases the external pressure. The processing unit is configured to detect a decrease in amplitude of the ICP waveform (occurring in some embodiments only after an intermediate period of ICRS compensation), the processing unit configured to determine the ICP of the person from a sum of applied external pressures from a time of the initial value A1 until a final value at which the amplitude remains stable with additional increase in applied external pressure. In some cases, the final value is earlier than that but the processing unit extrapolates the sum to when the amplitude remains stable with additional increases in pressure.

A medical diagnostic method, system and related equipment particularly adapted to diagnose disorders of the blood circulation serving the head and neck, and especially the brain. A preferred use of the system is early, rapid, accurate, diagnosis of stroke, especially whether the stroke is due to blockage of a blood vessel or leakage from the blood vessel.

A method is disclosed for generating sinograms by sampling a plurality of transducers acoustically coupled with the surface of a volume of tissue over a period of time after a light pulse at one wavelength, and after another light pulse at a different wavelength, and for processing those sinograms, reconstructing at least two optoacoustic images from the two sinograms, processing the two optoacoustic images to generate two envelope images and generating a parametric map from information in the two envelope images. In an embodiment, motion and tracking are determined to align the envelope images. In an embodiment, at least a second parametric map is produced from information in the same two envelope images. In an embodiment an ultrasound image is also acquired, and the parametric map is coregistered with and overlayed upon the ultrasound image, and then displayed.

One of the hybrid ultrasound and MRI devices includes a transducer array, a communications interface connected with the transducer array, and a housing that electromagnetically shields and encloses the transducer array and the communications interface. An electrically conducting side of the housing receives a radio frequency (RF) signal from an MRI system and transmits the RF signal to an electrically conducting side of a housing of another of the hybrid ultrasound and MRI devices.

A medical scan triaging system is operable to train a computer vision model and to generate abnormality data indicating abnormality probabilities for medical scans via the computer vision model. A first subset of medical scans is determined by identifying medical scans with abnormality probabilities greater than a first probability value of a triage probability threshold. A second subset of medical scans is determined by identifying medical scans with abnormality probabilities less than the first probability value. An updated first subset of medical scans is determined by identifying medical scans with abnormality probabilities greater than a second probability value of an updated triage probability threshold. An updated second subset of the plurality of medical scans is determined by identifying medical scans with a abnormality probabilities less than the second probability value. The updated first subset of medical scans is transmitted to client devices.
