The systems and methods disclosed herein provide determination of an orientation of a feature towards a reference target. As a non-limiting example, a system consistent with the present disclosure may include a processor, a memory, and a single camera affixed to the ceiling of a room occupied by a person. The system may analyze images from the camera to identify any objects in the room and their locations. Once the system has identified an object and its location, the system may prompt the person to look directly at the object. The camera may then record an image of the user looking at the object. The processor may analyze the image to determine the location of the user's head and, combined with the known location of the object and the known location of the camera, determine the direction that the user is facing. This direction may be treated as a reference value, or “ground truth.” The captured image may be associated with the direction, and the combination may be used as training input into an application.

A system for performing at least one impedance measurement on a biological subject, the system including a measuring device having a first housing including spaced pairs of foot drive and sense electrodes provided in electrical contact with feet of the subject in use, a second housing including spaced pairs of hand drive and sense electrodes provided in electrical contact with hands of the subject in use, at least one signal generator electrically connected to at least one of the drive electrodes to apply a drive signal to the subject, at least one sensor electrically connected to at least one of the sense electrodes to measure a response signal in the subject and a measuring device processor that at least in part controls the at least one signal generator, receives an indication of a measured response signal from the at least one sensor and generates measurement data indicative of at least one measured impedance value and a client device in communication with the measuring device, the client device being adapted to receive measurement data allowing the client device to display an indicator associated a result of the impedance measurement.

A bed system including an acquisition unit and a display, in which the acquisition unit acquires user interface device information from a plurality of user interface devices and the display displays a plurality of images corresponding respectively to the plurality of user interface devices on a single screen based on the user interface device information. One set of the plurality of user interface device information includes state information including at least one of bed state information relating to the state of one bed among a plurality of beds and user state information relating to the state of a user of the one bed among the plurality of beds. One image among the plurality of images includes a state display corresponding to the state information. When the state information is abnormal, the first display displays a warning display on the one image among the plurality of images.

A system includes a processor and an output device. The processor is configured to: (a) receive electrical signals indicative of measured positions of (i) one or more chest position sensors attached externally to a chest of a patient, and (ii) one or more back position sensors attached externally to a back of the patient; (b) compare between (i) a first shift between the measured positions and respective predefined positions of the one or more chest position sensors, and (ii) a second shift between the measured positions and respective predefined positions of the one or more back position sensors; and (c) produce an alert in response to detecting a discrepancy between the first and second shifts. The output device is configured to output the alert to a user.

The present invention relates to patient positioning. In order to improve patient positioning during a scan, an autonomous motion positioner is proposed using a critical range, which may correspond to maximum corrections achievable by the scanner hardware and the maximum tolerable image distortions. The critical range is determined based on one or more machine settings of the medical imaging system. As the machine setting(s) may vary in a given imaging exam, the critical range may dynamically change in response to a change of the machine setting in the given imaging exam. External sensors may measure, via a feedback loop, the deviation from the start position, i.e. the imaging pose position. If patient motion is too large and the motion parameter (e.g. translation and/or rotation) exceeds the determined critical range, then the scan process may be stopped. The autonomous scanner may hold in an idle mode. During that mode, the patient may be guided to retake its original position via a feedback system. A control loop may calculate critical range deviation and the scan process may be continued, if the motion parameter is less than the determined critical range. Accordingly, uncorrectable motion artefacts due to large body movements may be avoided. The motion positioner may be suitable for systems, such as MR, MR-LINAC, computed tomography (CT), and positron emission tomography (PET).

The computing system may subtract a three-dimensional scan of at least a portion of the subject from the three-dimensional mold model to define an opening therein. The computing system may remove, from the three-dimensional mold model, a first portion to define an imprint in the opening from a first axis along which the subject is to enter. The computing system may remove, from a second portion of the three-dimensional mold model remaining with the removal of the first portion, inward protrusions into the imprint of relative to the second axis intersecting the first axis.
