Abstract: Methods, systems, computer-readable media, and apparatuses for estimating a user's heart rate using a PG signal are presented. In some implementations, the heart rate is estimated by computing a frequency-domain PG, identifying one or more features in the frequency-domain PG, selecting qualified features from the one or more features, and constructing one or more traces. In some implementations, an accelerometer signal can be used for motion cancellation to eliminate traces that are motion artifacts.

Abstract: The present disclosure generally relates a fiducial marker deployment system configured for controlled deployment of at least one of a plurality of preloaded specially-configured fiducials in a controlled serial manner to a desired target site. The deployment system generally includes a deployment device configured to deploy at least one of a plurality of preloaded fiducials to a target site within a patient via a rotational deployment mechanism. Each fiducial generally includes a pellet-like body having a groove helically formed along an outer surface thereof and the deployment device includes a deployment catheter having an internally threaded lumen configured to engage the helical groove of each fiducial so as to allow rotational loading and deployment of each fiducial.
Abstract: The present invention relates to apparatus (10) for determining a respiration volume signal from a subject (12), comprising a processing unit (28) for receiving image data (26) detected from a field of view (42) and for determining an alternating signal (S) including vital sign information (R) of the subject (12) from the image data (26), an analysis unit (30) for determining at least one characteristic parameter (A) corresponding to a respiration parameter of the subject (12) on the basis of the alternating signal (S), a calibration unit (32) for determining a calibration value (V1, V2) on the basis of a breathing volume measured during inhale and/or exhale of the subject (12) by means of an airflow or an air volume measurement, and a calculation unit (34) for calculating the respiration volume of the subject (12) on the basis of the calibration value (V1, V2) and the at least one characteristic parameter (A).
Abstract: A method for performing an imaging scan of a subject includes positioning a narrow field-of-view camera at a first imaging position to acquire a first set of imaging information of a first object of interest, positioning the narrow field-of-view camera at a second imaging position to acquire a second set of imaging information of a second object of interest, determining emission counts for the first and second sets of imaging information, and utilizing the determined emission counts to generate a value that indicates a probability of a successful medical procedure being performed on the subject.

Abstract: A portable ultrasound system having dedicated power source devices is disclosed herein. In one embodiment, a portable ultrasound system can include transducer electronics and a base unit having base-unit electronics configured to receive user input and to operate the transducer electronics to perform ultrasound scanning based on the user input. The portable ultrasound system further includes a first power source device configured to power the transducer electronics and a second power source device configured to power the base-unit electronics without powering the transducer electronics.
