摘要： Exemplary embodiments provide an optical penile blood flow measuring technology for the monitoring of neurological and vascular function of structures at surgical risk. The measuring principle is to rely on optical absorption properties of blood components for penile blood flow monitoring. Certain embodiments use different wavelengths to measure changes in hemoglobin concentrations and are particularly advantageous in continuous, autonomous monitoring with real-time feedback to surgeons for potential intervention and decision-making in a timely manner. The measurements results can be used to provide real-time feedback to surgeons operating on the patient, or for off-line analysis and evaluation. Certain embodiments can operate autonomously in the continuous measurement mode, a synchronized mode, or a triggered mode, reducing the need of highly-skilled apparatus operators, allowing automatic and real-time warning to surgeons when operating in areas while preserving the functions of critical nerves, resulting in improved clinical outcomes and reducing operation costs.

摘要： In hemodynamic determination in medical imaging, the classifier is trained from synthetic data rather than relying on training data from other patients. A computer model (in silico) may be perturbed in many different ways to generate many different examples. The flow is calculated for each resulting example. A bench model (in vitro) may similarly be altered in many different ways. The flow is measured for each resulting example. The machine-learnt classifier uses features from medical scan data for a particular patient to estimate the blood flow based on mapping of features to flow learned from the synthetic data. Perturbations or alterations may account for therapy so that the machine-trained classifier may estimate the results of therapeutically altering a patient-specific input feature. Uncertainty may be handled by training the classifier to predict a distribution of possibilities given uncertain input distribution. Combinations of one or more of uncertainty, use of synthetic training data, and therapy prediction may be provided.

摘要： Systems, methods, apparatuses, and medical devices for harmonizing data from a plurality of non-invasive sensors are described. A physiological parameter can be determined by harmonizing data between two or more different types of non-invasive physiological sensors interrogating the same or proximate measurement sites. Data from one or more first non-invasive sensors can be utilized to identify one or more variables that are useful in one or more calculations associated with data from one or more second non-invasive sensors. Data from one or more first non-invasive sensors can be utilized to calibrate one or more second non-invasive sensors. Non-invasive sensors can include, but are not limited to, an optical coherence tomography (OCT) sensor, a bio-impedance sensor, a tissue dielectric constant sensor, a plethysmograph sensor, or a Raman spectrometer.

摘要： A system and method for monitoring blood oxygen levels via an eye tracking camera includes a computer system with a processor configured to identify capillaries in the image stream of a pilot's eye. Changes in capillary size over time is directly correlated to blood flow levels. The processor may monitor capillary color. Changes in capillary color is directly correlated to blood oxygen levels. The processor may take remedial action when the pilot's blood oxygen level drops below a threshold. Such remedial action may include alerting the pilot, automatically alerting ground control crew, applying increasing levels of flight automation, etc.

摘要： Systems and methods are disclosed for determining blood flow characteristics of a patient. One method includes: receiving, in an electronic storage medium, patient-specific image data of at least a portion of vasculature of the patient having geometric features at one or more points; generating a patient-specific reduced order model from the received image data, the patient-specific reduced order model comprising estimates of impedance values and a simplification of the geometric features at the one or more points of the vasculature of the patient; creating a feature vector comprising the estimates of impedance values and geometric features for each of the one or more points of the patient-specific reduced order model; and determining blood flow characteristics at the one or more points of the patient-specific reduced order model using a machine learning algorithm trained to predict blood flow characteristics based on the created feature vectors at the one or more points.
