Abstract
A system is disclosed for synchronizing the activation of an imaging device, such as an X-ray machine, with patient respiration. The imaging device includes a conventional trigger signal input for activating the imaging device in response to a preset signal. The system includes a respirator device, such as a ventilator or respiration band, which provides an output signal indicative of the degree of patient inspiration. A processing circuit is responsive to the output signal from the respiration device and generates the preset signal at a preselected degree of patient inspiration. The output signal from the processing circuit is coupled to the imaging device signal input to activate the imaging means at the preselected degree of patient inspiration.
Claims14
A system for synchronizing the activation of an imaging device with patient respiration as monitored by a respiratory device, said respiratory device operative to output a respiratory signal indicative of the degree of a patient's respiration during a respiration cycle, said imaging device having a signal input for activating the imaging device in response to a preset signal, said system comprising:
- a cycle processor optically coupled to said respiratory device such that said cycle processor is electrically isolated from said respiratory device and generates an electrical output signal that corresponds to said respiratory signal;
- and
- a generating device in communication with said cycle processor, said generating device outputting the preset signal to said imaging device in response to the electrical output signal received from said cycle processor.
