Described herein are example methods, devices and systems for motion compensation in ultrasonic respiration monitoring. A respiration detection system includes a first probe placed on a front side of a patient's body and a second probe placed on a dorsal side of the body. The first probe includes an ultrasound transducer, a first accelerometer unit and a magnetic field sensor unit, and the second probe includes a second accelerometer unit and magnetic field sensor unit. Due to respiration of the patient, the abdominal region of the body moves, creating measurement errors when an ultrasound beam is directed towards an internal structure (internal tissue region) inside the patient's body. Correction for such measurement errors uses input data from the first and second accelerometer units and the magnetic field sensor unit.

Systems and methods for motion compensation in ultrasonic respiration monitoring

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.

Ultrasonic method and apparatus for respiration monitoring

A chest compression device for cardiopulmonary resuscitation comprises a support structurefor placement about a patient's chest and for holding a chest compressorabove a patient's sternum; a chest compressormounted on the support structure; and lateral chest supportsattached to the support structureat points laterally either side of the chest when the device is in use, such that the lateral chest supportswill apply lateral pressure to the sides of the chest synchronized with a chest compression by the chest compressor

Chest compression device

Described herein are example ultrasonic transducer device probes configured to be placed on a patient's body to direct an ultrasonic beam towards an internal structure inside the body and receive ultrasonic echo signals from the internal structure. A probe includes a housing in which an ultrasonic transducer is located, a transceiving face of the transducer being at an acute angle relative to a front plane of the housing. An accelerometer unit and a magnetic field sensing unit are also housed inside the probe. The transducer, accelerometer, and magnetic field sensing unit are embedded in a body of a first material comprising ultrasound non-sonolucent material. A front face of the body of the first material and a recess extending down to the transceiving face is covered by a body of a second material comprising ultrasound sonolucent material having a tacky or non-tacky front surface.

Ultrasonic transducer device for respiration monitoring

A chest compression device for cardiopulmonary resuscitation may include a support structure for placement about a patient's chest and for holding a chest compressor above a patient's sternum; a chest compressor mounted on the support structure; and lateral chest supports attached to the support structure at points laterally on either side of the chest when the device is in use, such that the lateral chest supports will apply lateral pressure to the sides of the chest synchronised with a chest compression by the chest compressor.

A coil device is provided having a member adapted to extend around and conform to an outer surface of a subject and a conductor adapted to extend only once around a first portion of the subject. The coil device can be positioned about the subject in order to measure a volume of the subject. When placed about the subject in the presence of a relatively homogeneous magnetic field, the conductor can generate a signal indicative of a volume of the first portion of the subject. The coil device may also include two or more conductors separately generating signals indicating volumes of two or more corresponding portions of the subject. In some cases the coil device includes associated authorization data that can limit use of the coil device. Systems and methods incorporating the coil device are also provided.

Coil system and method for obtaining volumetric physiological measurements

A system and method for measuring volumes and areas using electromagnetic induction techniques. A current is generated and fed into one of two coil assemblies to induce voltage into another coil assembly to provide accurate values for volume or area.

Volumetric physiological measuring system and method

Embodiments of the present invention provide methods of extracting optimal information from a flow/volume loop concerning the patient's respiratory condition by examining the overall shape of the space under the flow/volume loop's expiration portion. In some embodiments, this is done with reference to the center of mass of that space. In some embodiments, this is done with reference to the area of that space. Some embodiments are significantly less affected by random/statistical variations and/or noise within the measurement system than existing methods.

Managing flow/volume loop information

The present invention relates to a magnetic resonance imaging (MRI) method, in particular to a MRI method enabling early detection of myocardial ischemia.
