Systems and methods describe providing for the intelligent assessment and analysis of medical patient data. In one embodiment, the system receives medical imaging data of a patient, as well as connected implant data from an implant device implanted in the patient. A number of features are extracted via artificial intelligence (AI) algorithms from the medical imaging data and connected implant data. One or more reports are then generated based on the extracted features. In some embodiments, the systems and methods provide for indices, features, information, and/or metrics which have clinical value, and which enable a surgeon to support his or her decisions (related to, e.g., diagnosis, prognosis, monitoring, or any other suitable subject area).

A magnetometer system for medical use comprises one or more induction coils for detecting a time varying magnetic field. Each coil has a maximum outer diameter of 10 cm or less, and a configuration such that the ratio of the coil's length to its outer diameter is 0.9 or more, and the ratio of the coil's inner diameter to its outer diameter is 0.6 or more. Each induction coil comprises a magnetic core. The magnetometer system further comprises a detection circuit coupled to each coil and configured to convert a current or voltage generated in the coil by a time varying magnetic field to an output signal for use to analyse the time varying magnetic field.

A system and/or method for diagnosing a neurologic condition. The system comprises a wearable head orientation sensor, a wearable eye imaging module, and a display with a visual target. The head orientation sensor is responsive to pitch or yaw head orientation information. The eye imaging module is configured for imaging a characteristic of the retina, sclera, cornea, limbus, or pupil to determine an eye position or eye movement.

The invention relates to a system and a method for detecting a surface shape of a human or animal body surface. A plurality of magnetic field sensors (2) arranged relative to one another in a sensor field (1) is placed on a plurality of surface regions of the body surface. A magnetic field generator (7) generates a magnetic field in the vicinity of the sensor field, so that a plurality of surface signals belonging to the surface regions are generated by using the magnetic field sensors (2). The surface signals serve as position signals with regard to the orientation and position of the magnetic field sensors in the magnetic field, so that the surface shape of the body surface is determined from the plurality of position signals of the magnetic field sensors (2) by using a signal processing unit (5).

The invention relates to a wearable device for determining a nature of motion and/or a physiological state of a wearer. The wearable device comprises a body portion configured to be worn by the wearer and at least one sensor mounted to the body portion configured to, while the wearable device is being worn, detect a motion parameter of the wearer and/or a physiological parameter of the wearer and generate input data indicative of the motion parameter and/or the physiological parameter. The wearable device further comprises a processor configured to receive the input data from the at least one sensor and process the input data by executing an algorithm to determine the nature of motion and/or the physiological state of the wearer while the wearable device is being worn. The invention further relates to a system for determining a nature of motion and/or a physiological state of a wearer.

A processing device includes a processor, the processor being configured to: acquire a captured image of an inside of a lumen; acquire lumen structure information indicating a structure of the lumen; determine whether the captured image can be analyzed or not and output analysis allowability/non-allowability information indicating whether the captured image is in an analysis allowable state or not based on the captured image and first determination criteria; associate the analysis allowability/non-allowability information with the structure of the lumen based on the analysis allowability/non-allowability information and the lumen structure information to identify an analyzable portion and an unanalyzable portion of the structure of the lumen; and determine that the identified unanalyzable portion is a missed portion based on position and orientation information of a distal end of an insertion section to be inserted in the lumen and second determination criteria.
