A method (10) for analyzing blood pressure measurements to determine any contextual or measurement tester related cause of the outlier. The method comprises identifying an obtained measurement as an outlier by comparing it with historical measurements for the subject. Any possible contextual cause of the outlier is first determined based on data in a database of contextual data for the subject. A database of historical measurement data for the tester who collected the measurement is then accessed and a determination made as to whether the outlier is attributable to the tester. Finally, the measurement, outlier status and any identified contextual or outlier-attributable cause are output. In embodiments, the measurement may be appended to a database, labelled as a true measurement and/or labelled with a cause for outlier status. Appending as a true measurement may be performed dependent on no determination being made of a contextual or tester-related cause of the outlier.

Accuracy enhancing systems, devices and methods are provided using data obtained from inertial measurement units (IMUs). IMUs are provided on one or more of a patient, surgical table, surgical instruments, imaging devices, navigation systems, and the like. Data from sensors in each IMU is collected and used to calculate absolute and relative positions of the patient, surgical table, surgical instruments, imaging devices, and navigation systems on which the IMUs are provided. The data generated by the IMUs can be coupled with medical images and camera vision, among other information, to generate and/or provide surgical navigation, alignment of imaging systems, pre-operative diagnoses and plans, intra-operative tool guidance and error correction, and post-operative assessments.

Provided are a method and an apparatus for measuring an endolymphatic hydrops ratio of inner ear organs using an artificial neural network. The method of measuring an endolymphatic hydrops ratio includes obtaining a plurality of frame images obtained by capturing inner ear organs, obtaining a plurality of pieces of mask data corresponding to each of the plurality of frame images by inputting the plurality of frame images into a neural network, clustering the plurality of pieces of mask data according to the inner ear organs and obtaining representative images according to the inner ear organs according to certain conditions, and overlapping a target image synthesized by using the plurality of frame images and the representative images according to the inner ear organs so as to measure an endolymphatic hydrops ratio.

An apparatus, system, and method for the measurement, aggregation and analysis of data collected using non-contact or minimally-contacting sensors provides quality of life parameters for individual subjects, particularly in the context of a controlled trial of interventions on human subjects (e.g., a clinical trial of a drug, or an evaluation of a consumer item such as a fragrance). In particular, non-contact or minimal-contact measurement of quality-of-life parameters such as sleep, stress, relaxation, drowsiness, temperature and emotional state of humans may be evaluated, together with automated sampling, storage, and transmission to a remote data analysis center. One component of the system is that the objective data is measured with as little disruption as possible to the normal behavior of the subject. The system can also support behavioral and pharmaceutical interventions aimed at improving quality of life.

Provided herein are methods for imaging and diagnosing at least one disorder in a patient utilizing diffusion basis spectrum imaging MRI with extended isotropic spectrum (DBSI-EIS). The methods may be used as a tool to image and diagnose heterogeneities within tumors. As a result, different tumor types can be detected, distinguished from one another, and individually quantified without the need to inject exogenous contrast agents.

One or more devices, systems, methods and storage mediums for performing optical coherence tomography (OCT) while detecting one or more lumen edges, one or more stent struts, and/or one or more artifacts are provided. Examples of applications include imaging, evaluating and diagnosing biological objects, such as, but not limited to, for Gastro-intestinal, cardio and/or ophthalmic applications, and being obtained via one or more optical instruments, such as, but not limited to, optical probes, catheters, capsules and needles (e.g., a biopsy needle). Preferably, the OCT devices, systems methods and storage mediums include or involve a method, such as, but not limited to, for removing the detected one or more artifacts from the image(s).

Arrangements, apparatus, systems and systems are provided for obtaining data for at least one portion within at least one luminal or hollow sample. The arrangement, system or apparatus can be (insertable via at least one of a mouth or a nose of a patient. For example, a first optical arrangement can be configured to transceive at least one electromagnetic (e.g., visible) radiation to and from the portion. A second arrangement may be provided at least partially enclosing the first arrangement. Further, a third arrangement can be configured to be actuated so as to position the first arrangement at a predetermined location within the luminal or hollow sample. The first arrangement may be configured to compensate for at least one aberration (e.g., astigmatism) caused by the second arrangement and/or the third arrangement. The second arrangement can include at least one portion which enables a guiding arrangement to be inserted there through. Another arrangement can be provided which is configured to measure a pressure within the at least one portion. The data may include a position and/or an orientation of the first arrangement with respect to the luminal or hollow sample.

Methods and systems for measuring tissue impedance and monitoring PVD treatment using neuro-implants with improved wireless powering are disclosed. In some embodiments, an implanted device including a wireless energy receiver, a demodulation circuit, and electrodes may be configured to received modulated energy from an energy transmitter. The implanted device may convert the energy to an electrical voltage to be applied to tissue to adjust the tissue's impedance. The tissue impedance may be measured with a computing system by receiving and processing an energy signal emitted/produced in response to the electrical voltage applied by the implanted device. In some embodiments, improved microwave powering schemes may be utilized to power the implanted device. In some embodiments, improved ultrasound powering schemes may be utilized to power the implanted device. For example, energy transfer efficiency from different transmitters may be evaluated to select for energy transmission the transmitter that yields optimal energy transfer efficiency.

An example of a display system includes a sensor, a projector, and control means. The sensor senses user information for calculating a state regarding sleep of a user. The user information is, for example, biological information such as pulse. The projector projects and displays a predetermined image. The projector, for example, projects the image upward to project and display the image on the ceiling. The control means controls the projector in accordance with a state regarding sleep, which is calculated on the basis of the user information.

An example information processing system executes a game application. The information processing system obtains user information for calculating information relating to sleep of a user, and calculates health information relating to sleep and/or fatigue of the user based on the obtained user information. The information processing system controls a game progress of the game application based on the health information.
