A method for detecting demineralization of a tooth substance, including the steps of irradiating (S101) a structured light pattern onto the tooth substance; detecting (S102) a light intensity of the light pattern remitted from the volume of the tooth substance; and determining (S103) demineralization of the tooth substance based on the detected light intensity.

A facial skin disorder (FSD) identification system is provided and includes a sliding rail arranged around a human facial epidermis, a carrier arranged on the sliding rail, at least one image capturing device arranged on the carrier, and a control circuit unit arranged on the carrier for the carrier to move on the sliding rail and the image capturing device to capture images of the human facial epidermis.

A pediatric head covering to facilitate obtaining three-dimensional images of a head of an infant to be utilized in manufacture of a cranial remodeling orthosis for correction of an abnormal head shape comprises sheer elastic material to be drawn down over an infant's head to compress the hair of an infant and to provide a smooth surface over the infant's cranium. The elastic material has variable elasticity with less elasticity over the crown of the cranium to provide enough strength to compress the infant's hair and conform to the shape of the cranium and more elasticity at the infant's neck to control soft tissue of the infant's neck without leading to distortion of the soft tissue and causing misrepresentations of the actual neck shape in captured three-dimensional images. The head covering facilitates accurate capture and reproduction of three-dimensional images of the infant's head by a three-dimensional image capturing system. The head covering is sized based upon anthropometric data derived from three-dimensional data sets of infant heads.

Apparatus and methods automate selection of patient interface(s). Image data captured by an image sensor may contain facial feature(s) of a user. The facial features may be captured in association with a predetermined reference feature of known dimension(s) such as with a user interface display that is generated with a sequence of icons that are activated for directing and tracking movement within the interface for desired image capture. The user's facial feature(s) and the reference feature may be detected in the captured image data. The image may be processed to measure an aspect of the detected facial feature(s) based on the reference feature. A patient interface size may be detected from standard patient interface sizes based on a comparison between the measured aspect of the facial feature(s) and a data record relating sizing information of the standard patient interface sizes and the measured aspect of the facial feature(s).

Systems and methods described herein are directed toward executing an intervention based on monitored physiological and/or environmental parameters according to some embodiments. In some embodiments, the system is configured to execute the intervention if one or more parameters are outside a pre-determined threshold. In some embodiments, an intervention can include and audible message. In some embodiments, the intervention can include taking control of a vehicle. In some embodiments, if there is no response from a user, the system will automatically contact a first responder and/or will automatically route the vehicle to an emergency facility. In some embodiments, the system includes one or more wearable monitoring devices that send signals to the system about physiological and/or environmental parameters. In some embodiments, the system uses artificial intelligence to determine if an abnormal condition exists.

A method (10) that encodes electrode locations to a mean scalp mesh for adaptation to subsequent image scans.

A method for controlling a scanner comprises: sensing an outer surface of a body of a subject to collect body surface data, using machine learning to predict a surface of an internal organ of the subject based on the body surface data, and controlling the scanner based on the predicted surface of the internal organ.

The present disclosure relates to the generation of partial surface models from volumetric datasets for subsequent registration of such partial surface models to surface topology datasets. Specifically, given an object that is imaged using surface topology imaging and another volumetric modality, the volumetric dataset is processed in combination with an approach viewpoint to generate one or more partial surfaces of the object that will be visible to the surface topology imaging system. This procedure can eliminate internal structures from the surfaces generated from volumetric datasets, thus increases the similarity of the dataset between the two different modalities, enabling improved and quicker registration.

The disclosed system uses a body shape capturing device for acquiring a patient's body shape and a 3D shape generating device for additively manufacturing a patient receiving device that is at least partially adapted to the patient's body shape or at least partially deviates from the patient's body shape bringing the patient's body into a desired shape so that the outer shape of the patient's body during surgery is identical to the outer shape of the body during shape capturing. The patient receiving device comprises at least one tracker element that is detectable by a detection system. The detection system captures data indicating the at least one tracker element's position and/or orientation during surgery enabling, particularly for surgical operations on or in soft tissues with high flexibly and with no specific natural or artificial landmarks, the surgeon to orientate/navigate in live images from the surgical site.

A purpose of the disclosure is to provide a measurement device for human bodies that can encourage a person who is reluctant to measure body composition to use the device. A measurement device has: an electric resistance value acquisition unit for acquiring an electric resistance value of one or more parts of a body of a person to be measured; and a type determination unit for using the electric resistance value to determine a type representing a physical characteristic of the person to be measured from one or more predetermined points of view.
