Abstract
A method of capturing radiographic images by wirelessly synchronizing steps performed by first and second components of a radiographic imaging system. Digital messages are sent between the first and second components and the send and receive times are recorded so that a transmission delay time and clock drift rate may be determined. A schedule of first component steps and a schedule of second component steps are generated based on the send and receive times, the transmission delay time and the clock drift rate.
Claims14
A method of capturing radiographic images of a subject using a radiographic imaging system, the radiographic imaging system including a first component and a second component, the method comprising:
- generating a schedule of first component steps to be performed by the first component, the schedule of first component steps each corresponding to a first component clock referenced by the first component to start or stop each of the first component steps;
- and
- generating a schedule of second component steps to be performed by the second component, the schedule of second component steps each corresponding to a second component clock referenced by the second component to start or stop each of the second component steps,
- wherein the steps of generating the schedule of first component steps and generating the schedule of second component steps comprise:
- sending a first digital message over a digital network from the first component to the second component and sending a second digital message over the digital network from the second component to the first component;
- determining a time tA1 of the first component clock when the first digital message was sent by the first component;
- determining a time tB1 of the second component clock when the first digital message was received at the second component;
- determining a time tA2 of the first component clock when the second digital message was received by the first component;
- and
- generating the schedule of first component steps and generating the schedule of second component steps based on one or more of the determined times tA1, tB1, and tA2, such that the first component steps and the second component steps are performed in synchrony.
