A surgical item managing method for use in a smart operating room to manage a surgical item used during a surgical procedure is provided. The surgical item includes a flexible RFID tag. The method includes the steps of: obtaining an information about a position of the flexible RFID tag; photographing a patient to obtain a position of the patient; determining if the position of the flexible RFID tag and the position of the patient overlap, to determine if the position of the flexible RFID tag is in the body of the patient; and giving a warning when the position of the flexible RFID tag is in the body of the patient.

A method for tracking the position of a person in an environment, such as a medical room, relative to a medical device is presented. The method comprises identifying the position of a medical device in the environment, providing a mobile device in the vicinity of a person in the environment, the mobile device configured to follow movement of the person in the environment, and identifying the position of the mobile device in the environment by using at least one stationary device. Further, the method comprises using a processor to process data relating to the position of the mobile device in the environment to obtain an expected position of the person in the environment, data relating to the position of the medical device in the environment, and data relating the expected position of the person in the environment to obtain an expected relative position of the person with respect to the medical device.

Disclosed herein is an apparatus for imaging nano magnetic particles using a 3D array of small magnets. A field-free region generation apparatus includes a hexahedral housing having an opening formed in the first surface thereof such that a measurement head is inserted into a spacing area, a pair of rectangular-shaped magnets installed respectively on two surfaces facing each other, among four surfaces perpendicular to the first surface of the housing, and a pair of magnet arrays installed respectively on the first surface of the housing and on another surface facing the first surface, each of the magnet arrays including multiple small magnets arranged along the edge of the opening.

A system for endurance testing including: at least one sensor configured to collect data associated with an individual's movement for an endurance test; an action module configured to determine endurance movements from the collected data and determine a set of test action; and an analysis module configured to analyze the set of test actions to provide a result for the endurance test. A method for endurance testing including: collecting data associated with an individual's movement, via at least one sensor; determining endurance movements from the collected data; determining a set of test action from the endurance movements; analyzing the set of test actions; and providing results associated with the endurance test based on the analyzed set of test actions.

A system includes a machine readable storage medium storing instructions and a processor to execute the instructions. The processor executes the instructions to receive radial k-space magnetic resonance imaging (MRI) data of a patient and determine a series of dipole sources via direct dipole decomposition of the radial k-space MRI data. The processor executes the instructions to identify an activation within the patient based on the series of dipole sources.

In a method and apparatus for supporting preparation of a patient for a medical imaging investigation, in particular a magnetic resonance investigation, patient data of a patient are acquired by operation of an acquisition unit. An item of position information of an object is calculated by a calculation computer, the calculation of the position information of the object taking place on the basis of the patient data and/or on the basis of an item of investigation information and/or on the basis of data from accessory units. The position information of the object is projected by means of a projection unit.

An electromagnetic tomography system for gathering measurement data pertaining to a human head includes an image chamber unit, a control system, and a housing. The image chamber unit includes an antenna assembly defining a horizontally-oriented imaging chamber and including an array of antennas arranged around the imaging chamber. The antennas include at least some transmitting antennas and some receiving antennas. The control system causes the transmitting antennas to transmit a low power electromagnetic field that is received by the receiving antennas after passing through a patient's head in the imaging chamber. A data tensor is produced that may be inversed to reconstruct a 3D distribution of dielectric properties within the head and to create an image. The housing at least partially contains the antenna assembly and has a front entry opening into the imaging chamber. The head is inserted horizontally through the front entry opening and into the imaging chamber.

Various embodiments concern video patient monitoring with detection zones. Various embodiments can comprise a camera, a user interface, and a computing system. The computing system can be configured to perform various steps based on reception of a frame from the camera, including: calculate a background luminance of the frame; monitor for a luminance change of a zone as compared to one or more previous frames, the luminance change indicative of patient motion in the zone; and compare the background luminance to an aggregate background luminance, the aggregate background luminance based on the plurality of frames. If the background luminance changed by more than a predetermined amount, then the aggregate background luminance can be set to the background luminance, luminance information of the previous frames can be disregarded, and motion detection can be disregarded.

An upper coil assembly for use with a lower RF coil assembly mounted to provide an RF probe arranged to be engaged with a head of a patient in MRI includes a plurality of coil loops arranged in a row defining a phase shift coil array with each coil loop including an independent output conductor for communicating signals to a respective preamplifier for independent amplification and each coil loop including a plurality of capacitors at spaced positions therearound. To decouple the loops each coil loop partly overlaps a next coil loop with a first decoupling capacitor shared on a common portion of each coil loop and each next coil loop. The first and third coil loops are also decoupled by using third decoupling capacitor in a connecting conductor between the first and third coil loops.
