A method for obtaining a spatial pattern of an anatomical structure of a subject includes comprising the steps of a) acquiring, from at least one digital image capturing device, at least one uncalibrated image of a calibration reference applied on a surface configured to receive the subject, the calibration reference having at least one known dimension and defining at least one known direction; b) defining an absolute calibrated reference system of three coordinates based on the calibration reference depicted in the at least one uncalibrated image; and c) acquiring, from the at least one digital image capturing device, at least a first and at least a second calibrated image of a plurality of markers applied on a corresponding plurality of body landmarks of the anatomical structure of the subject at respective contact points with the body landmarks, the plurality of markers being arranged within the absolute calibrated reference system,

To dramatically develop a technology for determining a mental and physical state of a subject by observing temporal dilation and contraction of a pupil in response to stimulus light, an eye of the subject is irradiated with stimulus light for 0.5 second under a state in which the pupil of the subject is not adapted to darkness. The pupil of the subject becomes smaller and then larger than the size at the time of irradiation with stimulus light. When the size of the pupil of the subject 5 seconds after the moment of irradiation with the stimulus light is larger than the size of the pupil at the moment of irradiation with stimulus light, a determination system determines that the subject is in a state in which a sympathetic nerve is dominant over a parasympathetic nerve.

Measurement apparatus (20) includes a garment (24, 26, 140, 160) including an elastic fabric (27) having a predefined pattern (28) extending across a surface thereof and configured to be worn over a part of a body of a subject (22), such that the elastic fabric stretches across the part of the body. A camera (30, 80) is configured to capture images of the pattern while contacting and traversing across the surface of the fabric while the subject wears the garment. At least one processor (32, 36, 60) is configured to process the images captured by the camera at multiple locations on the surface of the fabric so as measure a local deformation of the pattern at the multiple locations due to stretching of the fabric, and to compute a dimension of the part of the body responsively to the measured deformation.

Methods, systems and computer readable media for computerized prediction of body parameters such as body fat percentage (BFP) and modeling of a subject (e.g., a human body) are described.

Provided are a measurement support device, an endoscope system, a processor for an endoscope system, and a measurement support method capable of easily and highly accurately measuring the size of a subject. In the measurement support device related to one aspect of the invention, the position of a spot by measurement auxiliary light is measured, and information indicating the actual size of a subject is acquired on the basis of the measurement result to create and display a marker. Moreover, an optical axis of the measurement auxiliary light has an inclination angle that is not 0 degrees with respect to an optical axis of the imaging optical system in a case where the optical axis of the measurement auxiliary light is projected on a plane including the optical axis of the imaging optical system.

Disclosed is a non-transitory computer-readable recording medium recorded with a cardiopulmonary resuscitation training program executable by a processor of an information processing apparatus, the cardiopulmonary resuscitation training program causing the processor to perform operations including evaluating a posture of a person who is performing chest compressions, based on posture information indicating the posture obtained from a posture detection apparatus and ideal posture information indicating an ideal posture for the chest compressions stored in a storage unit, to yield an evaluation result, and displaying the evaluation result on a display apparatus.

In a foot size measurement system, a measurement unit selectively measures one or more of multiple measurement elements to be measured as feature values defining one foot size, based on a one-foot image of a measured person. An information generator generates foot size information based on one or more measurement elements selectively measured by the measurement unit, among the multiple measurement elements. An output unit outputs the foot size information. The measurement unit selectively measures one or more of multiple measurement elements including a foot width and a foot length of one foot of a measured person.

An ultrasound transducer assembly that includes a piezoelectric layer configured to resonate and generate ultrasound signals around a predetermined ultrasound frequency in which the piezoelectric layer has a width to thickness ratio of at least about 0.6. A conductive matching layer is connected to the top surface of the piezoelectric layer to condition the ultrasound transducer for broad frequency bandwidth operation. A conductive backing layer is connected to the bottom surface of the piezoelectric layer. The ultrasound transducer assembly further includes a rigid body over which the conductive backing layer is positioned, the rigid body assembled for encompassing a central longitudinal axis of a catheter body. A signal and ground electrode may form a metallic layer over the top of or below each of the piezoelectric layers. Electrical waveguides may be connected to corresponding signal and ground electrodes of the transducers.

To measure a body size with increased convenience, a body measurement device including a camera configured to capture an image that includes an RGB image and a depth image, a display, and a controller configured to acquire a source image that includes a skeleton image and a body line image of a user based on the captured image, acquire a body size including a body height based on the source image, and control the display to display the body size is provided.

Systems and methods may be used for evaluating a patient after completion of an orthopedic surgery on a portion of a body part of the patient. In an example, the method includes capturing, using a camera of the device, a series of images of the patient in motion, determining respective lengths of the body part in each of the series of images based on comparing the body part in each of the series of images to a skeletal model, and identifying a maximum length of the body part from the respective lengths. The method may include displaying an indication corresponding to the maximum length.
