Systems and methods are provided for detecting and analyzing changes in a body. A system includes an electric field generator, an external sensor device, a quadrature demodulator, and a controller. The electric field generator is configured to generate an electric field that associates with a body. The external sensor device sends information to the electric field generator and is configured to detect a physical change in the body in the electric field, where the physical change causes a frequency change of the electric field. The quadrature demodulator receives the electric field from the electric field generator and is configured to detect the frequency change of the electric field and to produce a detected response. The controller, coupled to the electric field generator, is configured to output a frequency control signal to the electric field generator and to modify the frequency of the electric field by adjusting the frequency control signal.

A bed monitoring system for monitoring a subject on a bed includes: a plurality of load detectors which are to be placed in the bed or under legs of the bed and which are configured to detect a load of the subject; a center of gravity position calculating unit configured to obtain a temporal variation of a center of gravity position of the subject based on the detected load of the subject; a body motion information determining unit configured to obtain a body motion information based on the obtained temporal variation of the center of gravity position of the subject, the body motion information being an information on a movement of a whole or a part of the whole body of the subject different from a movement caused by a respiration of the subject; a respiratory rate calculating unit configured to calculate a respiratory rate of the subject based on the obtained temporal variation of the center of gravity position of the subject and the body motion information obtained by the body motion information determining unit; and a subject information detecting unit configured to detect at least one of an image information of the subject, an audio information of the subject and a temperature information of the subject.

A method is for carrying out an imaging scan of a patient in a computed tomography system. In an embodiment, the method includes acquiring a respiratory cycle of the patient; providing the respiratory cycle as a reference respiratory cycle; selecting at least one respiratory phase of the reference respiratory cycle, shorter than a cycle period of the reference respiratory cycle; and carrying out the imaging scan in the computed tomography system. A respiration of the patient is acquired and is transferred as a respiratory signal progression; the respiratory signal progression is compared with the at least one selected respiratory phase of the reference respiratory cycle, by which a binary comparison result is generated; and dependent upon the binary comparison result, a data acquisition is triggered in the computed tomography system, by which projection data is acquired in the at least one respiratory phase.

A method of registering a real-time image feed from an imaging device inserted into a steerable catheter using a navigation system is provided. The method includes inserting the imaging device into a working channel of the steerable catheter and generating a real-time image feed of one or more reference points, wherein the orientation of the reference points is known. The method further includes orienting a handle of the steerable catheter to a neutral position, displaying the real-time image feed on a display of the navigation system, and registering the real-time image feed to the steerable catheter by rotating the displayed image so that the reference points in the real-time image feed are matched to the known orientation of the reference points.
