1. A method of obtaining imaging data from a patient, the method comprising:
- receiving from a sensor a plethysmographic signal;
determining, using a processor, respiration information based on the plethysmographic signal; and
gating an imaging device based on the respiration information.

Abstract
A method and system for automatically gating an imaging device is disclosed. Physiological process information of a patient may be derived from a plethysmographic signal, for example, by analyzing the plethysmographic signal transformed by a continuous wavelet transform. Other techniques for deriving physiological process information of a patient include, for example, analyzing a scalogram derived from the continuous wavelet transform. The physiological process information may be used to automatically gate imaging data acquired from an imaging device in order to synchronize the imaging data with the physiological process information.
