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.

A method of gating an application of radiation for a CT procedure, comprising:
- obtaining signal data representative of at least a portion of a physiological movement to form a set of ordered measurement samples;
- comparing the set of ordered measurement samples against prior measurement samples of the physiological movement to determine deviation from periodicity of the set of ordered measurement samples;
- and
- gating CT radiation to the patient if the deviation from periodicity is outside a threshold range.
A method for gating an application of radiation to a patient, comprising:
- directing a camera at a patient;
- generating image data representative of a physiological movement of the patient;
- analyzing the image data against an established range interval for applying radiation;
- and
- gating an application of radiation to the patient based upon the analyzing.
A method for collecting image data, comprising:
- acquiring image data of at least a part of an object over a time interview;
- and
- sorting the image data based on a portion of a cycle of a motion of the object at which the image data are acquired.
A method for applying radiation to a patient, comprising:
- determining a period of periodic physiological movement;
- defining an interval range over a portion of the period of the periodic physiological movement for applying radiation;
- determining an amount of time required to actuate a component of a radiation device such that radiation is applied within the interval range;
- and
- predictively actuating the component to compensate for the amount of time required to actuate the gating component.
A method for prompting a patient in a physiological activity, comprising:
- displaying an image, the image simultaneously showing visual real-time feedback for the physiological activity, and a desired range for the physiological activity;
- and
- prompting the patient to maintain the physiological activity within the desired range.
