The present invention relates to a device, system and method for determining the core body temperature of a subject. To enable continuous core body determination without having to place or direct a sensor at a precise position of the subject's body, the device comprises an image data input (31) for obtaining image data (11) of a subject's skin, a thermal sensor data input (32) for obtaining thermal sensor data (21) of the subject's skin, an image analysis unit (33) for deriving photoplethysmography, PPG, signals from the obtained image data and for detecting one or more skin areas (34) having the strongest PPG signals, and a temperature determination unit (35) for determining the core body temperature (36) of the subject from obtained thermal sensor data for the detected one or more skin areas.

According to an aspect of some embodiments of the present invention there is provided a method of dynamically adapting a facial treatment based on a current facial skin profile, comprising: using at least one sensor for measuring at least one current value of at least one variable skin characteristic of facial skin of a patient; acquiring at least one personal skin characteristic of facial skin of the patient; calculating a current facial skin status of the patient according to the at least one personal skin characteristic and the at least one current value; determining instructions to operate a treatment applicator according to the current facial skin status; and instructing the treatment applicator according to the instructions.

A lesion detecting method and a lesion detecting apparatus for breast image in a rotating manner are provided. In the method, a set of breast image in the rotating manner is obtained. The set of breast image in the rotating manner contains sub breast images. The sub breast image is reconstructed, to generate a reconstructed breast image. The reconstructed breast image is compared with the set of breast image in the rotating manner without being reconstructed. Accordingly, at least one lesion position would be confirmed according to the comparing result. Therefore, viewing a three-dimensional breast image would be convenient for medical staff, and false positive of detecting lesion would be reduced.

The present inventive concept relates to an optical coherence tomography (OCT)-based intraoral scanner calibration device including: a light source; an optical coupler for splitting the path of light irradiated from the light source in first light and second light; a reference part for generating reference light from the first light split by the optical coupler; a sample part for generating measurement light from the second light split by the optical coupler; and a signal generator for generating an OCT image from the reference light and the measurement light.

Systems and methods for planning the position of surgical hardware to be robotically implanted in a subject. The system extracts information about the planned position of hardware from an operative plan based on preoperative images, and converts this information into mathematical vectors. Intraoperatively, at least one three-dimensional scan of the operative site is obtained. The intraoperative images are processed by image analysis, to which are applied artificial intelligence algorithms for feature identification. The vectors derived from the preoperative plan are superimposed on identified anatomical features from the processed intraoperative images. The surgical plan can then be updated intraoperatively, taking into account any shift in position of the anatomical features between the preoperative images and the intraoperative images, prior to robotic insertion of the hardware.

A computer aided diagnostic system and automated method to classify a kidney utilizes medical image data and clinical biomarkers in evaluation of kidney function pre- and post-transplantation. The system receives image data from a medical scan that includes image data of a kidney, then segments kidney image data from other image data of the medical scan. The kidney is then classified by analyzing at least one feature determined from the kidney image data and the at least one clinical biomarker.

A method of visualizing spinal nerves includes receiving a 3D image volume depicting a spinal cord and a plurality of spinal nerves. For each spinal nerve, a 2D spinal nerve image is generated by defining a surface within the 3D volume comprising the spinal nerve. The surface is curved such that it passes through the spinal cord while encompassing the spinal nerve. Then, the 2D spinal nerve images are generated based on voxels on the surface included in the 3D volume. A visualization of the 2D spinal images is presented in a graphical user interface that allows each 2D spinal image to be viewed simultaneously.

A dynamic analysis system includes an imaging device and an analysis device. The imaging device performs dynamic imaging by emitting radiation to a chest part of a human body, thereby obtaining a series of frame images showing a dynamic state of the chest part. The analysis device includes a controller. The controller (i) selects a first plurality of frame images to be analyzed from the series of frame images obtained by the imaging device, (ii) calculates, based on the first plurality of frame images, a ventilation amount index value that indicates an amount of ventilation of a lung field and a perfusion amount index value that indicates an amount of perfusion of the lung field, and (iii) calculates a ratio of the ventilation amount index value to the perfusion amount index value.

A method for facilitating a tooth repositioning dental treatment includes: receiving a CT scan of a patient's oral dental structure, receiving an optical scan of the patient's oral dental structure, aligning the CT scan and the optical scan, establishing an initial model of the patient's oral dental structure based on the CT scan and the optical scan, simulating tooth movements to produce a final model of the patient's oral dental structure after the tooth repositioning dental treatment, generating a plurality of models of the patient's oral dental structure representing successive tooth movements from the initial model to the final model, and preparing dental aligners based on the plurality of models of the patient's oral dental structure.

A method for monitoring the shape of teeth including: producing a three-dimensional digital model of at least one portion of an arch of the patient or “initial reference model”; acquiring at least one two-dimensional image of the arches, referred to as “updated image”, under actual acquisition conditions; analysing each updated image and producing an updated map relating to a piece of discriminating information; optionally determining rough virtual acquisition conditions that approximate the actual acquisition conditions; searching each updated image for a final reference model corresponding to the shape of the teeth, and optionally to the positioning of the teeth, during the acquisition of the updated image; and comparing the shapes of the initial reference model and of the reference model obtained at the end of the preceding steps, referred to as “final reference model”, in order to determine the deformation and/or the movement of teeth between steps a) and b).
