The invention provides methods for diagnosing, assessing or quantitating drug use, drug abuse or narcosis or for differentiating drug use, drug abuse or narcosis from brain injury in a subject by tracking eye movement of at least one eye of the subject, analyzing eye movement of at least one eye of the subject, comparing eye movement of at least one eye of the subject the normal or mean eye movement; and, optionally calculating a standard deviation or p value for eye movement of at least one eye of the subject as compared to the normal or mean eye movement.

Apparatus and methods are described for setting rehabilitation goals for a patient, measuring patient movements, storing the movement data for later transfer to a computer, displaying progress indicators and inspirational messages based on progress towards goals, reporting movement, skin temperature and swelling data to a caregiver so that they monitor compliance and be aware of potential infection. The invention consolidates data from motion, temperature and swelling sensors placed on the patient with data received directly from the patient in response to questions displayed on a tablet computer screen, to create one or more representative values indicating the patient's current status. These representative values may include the patient's degree of compliance with their prescribed exercise and icing regimen; their degree of wellness based on their self-reported pain scale and sensed temperature and limb swelling; and their current level of physical activity as detected by the motion sensors.

An ultrasound diagnostic apparatus (1) includes an ultrasound probe (2) having a predetermined size; and a portable diagnostic apparatus main body (3), in which the diagnostic apparatus main body (3) includes a camera (25) that captures an optical image including a wound region of a subject and the ultrasound probe, an image generation unit (22) that generates an ultrasound image for the wound region, a monitor (24) that displays the optical image and the ultrasound image, an extraction unit (26) that extracts the wound region and the ultrasound probe from the optical image, and a wound size calculation unit (27) that calculates an actual size of the wound region on the basis of the predetermined size of the ultrasound probe (2) by comparing the extracted wound region and the extracted ultrasound probe (2), and displays the actual size on the monitor (24).

A method for vascular assessment is disclosed. The method includes receiving a plurality of medical images of a portion of a vasculature of a subject and processing the medical images to produce a model of the vasculature. The method further includes obtaining a flow characteristic of the model and calculating an index indicative of vascular function, based, at least in part, on the flow characteristic in the model.

A device for taking a measurement of a dimension of a part of the body of a patient, includes: an electronic tape measure having a portable housing, a winder accommodated in the housing, a tape which is partially wound on the winder and of which a portion, called the “unwound portion”, extends outside the housing, and a measuring module for a measurement, relative to the unwound portion; a consistency control module for checking the consistency of the measurement by at least one consistency rule and at least one context datum; and an alert module for delivering an alert if an inconsistency is detected by the consistency control module.

A measurement device for measuring the circumference of a human head. The measurement device includes a generally circumferential body that fits around a human head. The generally circumferential body has a receiver segment with an elongated geometry. The receiver segment includes an adjustment end receiver. The receiver segment is flexible. The generally circumferential body also has an adjustment segment with a measurement end. The adjustment segment measurement end has a diameter that is narrower than the receiver segment adjustment end receiver diameter. The adjustment segment has a measurement indicator that extends from the measurement end. The adjustment segment is flexible. The adjustment segment measurement end is adjustably inserted into the receiver segment sliding end receiver. The visual measurement indicator is operable with respect to the receiver segment adjustment end receiver.

A sleeve or sheath includes a body having a top opening. The body covers a handheld oximeter probe or a portion of the probe. The sleeve has a shape that approximately matches the oximeter probe or portion of the probe, which is covered by the sleeve. The sleeve has a top opening that allows a user to slide the oximeter probe into the sleeve. The sleeve is transparent to radiation emitted and collected by the oximeter probe. The sleeve is formed of a material that prevents patient tissue, fluid, viruses, bacteria, and fungus from contacting the covered portions of the oximeter probe. The sleeve leaves the probe relatively sterile after use so that little or no clearing of the probe is required for a subsequent use, such as when the probe is covered with a new, unused sleeve.

Systems are provided for generating data representing electromagnetic states of a heart for medical, scientific, research, and/or engineering purposes. The systems generate the data based on source configurations such as dimensions of, and scar or fibrosis or pro-arrhythmic substrate location within, a heart and a computational model of the electromagnetic output of the heart. The systems may dynamically generate the source configurations to provide representative source configurations that may be found in a population. For each source configuration of the electromagnetic source, the systems run a simulation of the functioning of the heart to generate modeled electromagnetic output (e.g., an electromagnetic mesh for each simulation step with a voltage at each point of the electromagnetic mesh) for that source configuration. The systems may generate a cardiogram for each source configuration from the modeled electromagnetic output of that source configuration for use in predicting the source location of an arrhythmia.

Systems and methods for determining position and orientation of a bone of an anatomical feature are described. These include the use of a wearable holder configured to be mounted about an outer-skin surface of the anatomical feature, such that the anatomical feature and the bone are positioned in fixed relation with respect to the wearable holder when the wearable holder is mounted about the anatomical feature. Reference marker arrays are fixedly mounted to the wearable holder, each being positioned on the wearable holder to identify a landmark of the bone within the wearable holder when the wearable holder is mounted to the anatomical feature. The position and orientation of the reference markers are trackable to determine position and orientation of the wearable holder in a reference coordinate system, thereby enabling position and orientation of the landmarks on the bone to be determined.

A early detection device to diagnose scoliosis in adolescents without exposure to harmful x-rays provides a portable, accurate and inexpensive hand-held diagnostic tool to determine deviations from the Cobb Angle in the spine, the detection device connecting to a receiver unit to receive data obtained from the detection device completing the diagnostic testing for visual review and diagnosis on the receiver unit. It is also provided in alternative embodiment to test the integrity of structural components in various industries, including surface irregularities and defects and cracks in beams and wall, pipes or beams.
