A method of non-invasively monitoring the respiration of a patient comprises: transmitting ultrasound into the body toward an internal structure of the patient's body, the internal structure being one of the liver, the spleen or a kidney; selecting a depth range; measuring the phase of ultrasound echo signals from the internal structure at multiple points along the depth range for at least a first and a second echo signal, the first and second echo signals being received at different times; detecting the motion of the internal structure within the patient's abdomen by reference to differences in the measured phase between the first and the second echo signals; and thereby monitoring the respiration of the patient by associating movement of the internal structure with movement caused by respiration.

A processing device for a radiation device is configured to carry out the steps of retrieving, from a data storage, volume data of a subject that was generated by imaging an internal structure of the subject, determining a position of an object in the subject based on the retrieved volume data of the subject, obtaining geometry information including a position of a radiation source and a position of a radiation detector, and obtaining a direction of the radiation detector, and determining a condition for imaging with the radiation source, so that the object can be captured through the imaging, based on the volume data, the position of the object, the position of the radiation source, the position of the radiation detector, and the direction of the radiation detector.

The present disclosure describes a technology for contactless cardiopulmonary system monitoring, and more specifically, to the embodiment of exemplary system and method for detecting torso movements and estimating respiratory and heart rates. This invention leverages a depth sensor-equipped camera system to determine the human's anatomical landmarks. The estimated coordinates guide an FMCW radar to enhance the signal quality in the direction of the subject through a beam-steering technique, and extract the movements corresponding to the cardiopulmonary system. The movements are used to estimate respiratory and heart rates in a processing unit.

A camera assembly for use in medical tracking applications having a range camera and a thermographic camera in a fixed relative position. The range camera is configured to acquire a first image of an object at a first instant of time and a second image at a second instant of time. The thermographic camera is configured to acquire a first thermal image of the object at the first instant and a second thermal image at the second instant. A processor identifies at least one point pair in the first thermal image and the second thermal image. The at least one point pair is mapped to corresponding point pairs associated with the first image and the second image. Movement of the object is determined based on the mapping.

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.
