Provided is an optical metal detector device (10) for preparing magnetic resonance imaging, MRI, comprising: a light (11) configured to emit light to illuminate a subject (S), a camera (12) configured to be positioned in multiple different positions relative to the subject, to capture a series of images of the illuminated subject and to provide assigned image signals, a linear polarizer (13) configured to be arranged in at least a first angular position and a second angular position relative to the subject, the first angular position and the second angular position are different to each other, and to polarize the light emitted by the light source or to polarize the image captured by the camera, and a data processing means (14) configured to obtain at least the image signals from the camera, wherein the data processing means is further configured to combine the image signals associated with the first angular position and the second angular position of the linear polarizer and the image signals associated with one or more of the multiple different positions of the camera to obtain a combined signal and to compare the combined signal with a threshold indicating a quantity of foreign metal objects on the subject. Thereby, combining the image signals with each other comprises a convolution operation.

A method of determining axial alignment of a lower limb includes determining a three-dimensional volume based on a scan of a lower limb of a patient, identifying a level of hip version by referring to a first axis of symmetry of a femoral neck and a second axis of symmetry of a distal portion of a femur, wherein hip version is defined by an angle between the first axis of symmetry and the second the second axis of symmetry, identifying a level of tibial torsion by referring to a third axis of symmetry of a proximal portion of a tibia and a fourth axis of symmetry of a distal portion of the tibia, wherein tibial torsion is defined by an angle between the third axis of symmetry and the fourth axis of symmetry, and providing the level of hip version and the level of tibial torsion to a user.

The present invention discloses a device for acquiring a functional image of tissue and a method for acquiring a functional image by using same, the device comprising: a light source for irradiating a tissue to be imaged with coherent light; an image acquisition unit for acquiring an image of a speckle pattern which is formed by scattering the light emitted from the light source over the tissue, and acquiring multiple images having different exposure times; an image processing unit for generating a functional image of the tissue on the basis of the multiple images acquired by the image acquisition unit; and a control unit for adjusting the light quantity of the light emitted to the tissue such that the multiple images having different exposure times have brightness values in a common range, and controlling the operation of the image acquisition unit.

Customized nipples are provided herein that are designed to mimic a woman’s anatomic nipple to improve experiences such as breast feeding, soothing a baby, and/or superior aesthetics. The customized nipples are created in a noninvasive manner, for example, via a scan of the woman’s breast that is received by a computer. The scan may be processed with enhanced computing power to provide the optimal customized nipple for the woman. The customized nipples may be formed for baby/nipple/nursing products such as bottles, pacifiers, nipple shields, breast pump flanges, attachments for supplemental nursing systems, and prosthetic nipples.

Instruments and methods for wide-field polarized imaging of the skin to determine an outer lesion margin objectively in vivo to provide guidance to a surgeon. Quantitative characterization of collagen structures in the skin can be used to determine the outer lesion margin or monitor skin treatment.

An overdose of opioids can cause the user to stop breathing, resulting in death. A physiological monitoring system monitors respiration based on oxygen saturation readings from a fingertip pulse oximeter in communication with a smart mobile device and sends opioid monitoring information from the smart mobile device to an opioid overdose monitoring service. The opioid overdose monitoring service notifies a first set of contacts when the opioid monitoring information indicates a non-distress stats and notifies a second set of contact when the opioid monitoring information indicates an overdose event. The notification can be a phone call or text message to a specified person, emergency personnel, or first responders, and can include the location of the smart mobile device. The smart mobile device can also include the location of the nearest treatment center having emergency medication used in treating opioid overdose, such as naloxone.

An automatic tattoo apparatus can be used to robotically apply tattoos. A customer can shop on an online tattoo marketplace to select designs created by various artists located anywhere. The online tattoo marketplace can process and manage payments, artist and/or customer profiles, bookings, tattoo design uploads, browsing and design selection, design changes, and/or perform other actions. The automatic tattoo device can apply tattoos precisely, quickly, and may with reduced pain. The tattoo apparatus can apply a wide range of different types of tattoos, including but not limited to micro tattoos, dotwork, blackwork tattoos, realism tattoos, fine-line tattoos, etc.

An arrangement is provided for monitoring the plantar temperature of the foot having a platform with at least two multi-layer temperature sensitive pads that measure the temperature of a sole of a user's feet. The platform has a scanner for scanning the bottom of the user's feet that produces a digital image thereof. A printed circuit board supports remote connectivity to a mobile application that transmits the scanned digital image of the users' feet to the mobile application for storage and delivery to a physician. The arrangement includes the mobile application that provides a series of diagnostic questions and prompts to the user and is configured to transmit data including the scanned images of the user's feet to a physician.

An obstructive sleep apnea detection device including an optical engagement surface adapted to engage a user's skin; a light source adapted to emit light from the optical engagement surface; a photodetector adapted to detect light at the optical engagement surface and to generate a detected light signal; a position sensor adapted to determine patient sleeping position; a controller adapted to determine and record in memory blood oxygen saturation values computed from the detected light signal and user position information from the position sensor; and a housing supporting the optical engagement surface, the photodetector, the light source, the position sensor, and the controller.

Techniques for automatic measurement using structured lights are provided. A computer system uses structured lights to acquire skin information, the skin information being associated with at least one affected area of the skin. The computer system determines parameters related to the at least one affected area of the skin, at least partly, on the skin information and generates an assessment for the at least one affected area of the skin.
