Abstract: A camera sensitive to near infrared light is placed proximate to the skin of a user and the area illuminated by one or more infrared light sources. A set of images of one or more blood vessels is obtained at successive times. The images are processed to determine a change in size of the vessel(s) from one time to another, corresponding to expansion and contraction of the vessels responsive to contraction of the user's heart. This change may be used to determine pulse rate, elasticity of the vessel, blood pressure, or other data about the user's physiological status. The data may be used to assess health status at a particular time, determine health trends for the user, and so forth.

Abstract: A magnetic resonance (MR) imaging device repeatedly executes a navigator pulse sequence to generate navigator data in image space as a function of time, and a motion signal of an anatomical feature that moves with a physiological cycle as a function of time is extracted from the navigator data. A concurrent physiological signal as a function of time is generated by a physiological monitor concurrently with the repeated execution of the navigator pulse sequence. A gating time offset is determined by comparing the motion signal of the anatomical feature as a function of time and the concurrent physiological signal as a function of time. The MR imaging device performs a prospective or retrospective gated MR imaging sequence using gating times defined as occurrence times of gating events detected by the physiological monitor modified by the gating time offset.
