Example defibrillator electrode assemblies compression assemblies are described that may be dimensioned and configured for use on a patient despite physical constraints that limit the area or locations on a patient onto which an electrode assembly may be placed. A cardio pulmonary resuscitation (CPR) assembly is also described that protects a patient with a transthoracic incision from further injury during application of CPR compressions proximate to the incision.

Provided are a heart physiological parameter measurement method, device and terminal, and a computer storage medium. The method comprises: respectively obtaining back vibration information and shoulder vibration information of an object to be measured in a supine state by means of one or more shoulder vibration sensitive sensors and back vibration sensitive sensors; respectively generating first hemodynamic related information and second hemodynamic related information on the basis of the back vibration information and the shoulder vibration information, the second hemodynamic related information comprising right shoulder second hemodynamic related information generated from right shoulder vibration information; determining a reference AVC time point of an AVC event on the basis of the first hemodynamic related information; and determining an AVC feature point of the AVC event on the basis of the reference AVC time point and the right shoulder second hemodynamic related information.

Apparatus for monitoring a clinical condition of a subject is described. At least one motion sensor detects motion of the subject and generates a sensed motion signal responsive to the sensed motion. A signal analyzer is adapted to determine a heartbeat-related signal from the sensed motion signal, to determine a first breathing-rate-related signal from the heartbeat-related signal, and to determine a second breathing-rate-related signal directly from the sensed motion signal. The signal analyzer determines the validity of the heartbeat-related signal by comparing the first breathing-rate-related signal with the second breathing-rate-related signal. Other applications are also described.

A dynamic analysis device includes a processor. The processor performs filtering on a dynamic image in a feature quantity space formed of two or more axes with feature quantities of the respective axes. The dynamic image is obtained by dynamic imaging performed by emitting radiation to an examination target site. Further, the processor calculates a feature quantity relating to a dynamic state of the examination target site based on the filtered dynamic image.

A method is disclosed for generating a motion-corrected PET image of an examination area in a combined MR-PET system. In an embodiment, the method includes recording PET events from the examination area in a first recording time frame; recording a number of MR images of the examination area in at least the first recording time frame; calculating an at least two-dimensional movement information of the examination area on the basis of the number of MR images, wherein the movement information describes the movement information of the examination area during the first recording time frame, and determining the motion-corrected PET image from the PET events using the calculated movement information.

Various devices, systems and methods for performing targeted sleep tracking are presented herein. Multiple digital radar data streams from multiple antennas may be received. A direction optimization process may be performed to determine a first weighting and a second weighting. The first weighting may be applied to a first digital radar data stream. The second weighting may be applied to a second digital radar data stream. The weighted first digital radar data stream and the weighted second digital radar data stream may be combined to create a first directionally-targeted radar data stream. A sleep analysis can be performed based on the first directionally-targeted radar data stream. Sleep data may be output for a user based on the performed sleep analysis.
