Abstract
A method for generating one or more images includes collecting data samples representative of a motion of an object, acquiring image data of at least a part of the object over a time interval, synchronizing the data samples and the image data to a common time base, and generating one or more images based on the synchronized image data. A method for generating one or more images includes acquiring image data of at least a part of an object over a time interval, associating the image data with one or more phases of a motion cycle, and constructing one or more images using the image data that are associated with the respective one or more phases.
Claims18
A method for gating an application of radiation to a patient, comprising:
- directing a camera at a patient;
- generating image data representative of a position of the patient associated with a physiological movement of the patient;
- obtaining an amplitude value and a phase value based at least in part on the image data;
- combining the amplitude value and the phase value to form a vector;
- performing an analysis using the vector;
- and
- gating an application of radiation to the patient based upon a result from the act of performing the analysis.
