Classification: CPC A | IPC A

Claim 0:
1. A synchronization device for determining an instant of a respiratory cycle of a patient in order to assist a medical intervention on said patient, said device comprising:
a locating device,
a reference device which comprises radiopaque markers, configured to be positioned on a body of the patient,
at least one locating element configured to be detectable by the locating device, wherein the at least one locating element including a marker,
an X-ray imaging device, and
an X-ray detector configured to cooperate with the X-ray imaging device,
a memory; and
a processor, the processor coupled to the memory and configured to:
record and process data obtained from the locating device and the reference device,
wherein the locating device is configured to continuously record movements of the reference device, the movements of the reference device corresponding to a respiratory cycle of the patient, and to transmit to the processor data relating to the movements of the reference device, in that the X-ray detector is configured to detect when a medical image has been taken by the X-ray imaging device and to transmit the corresponding data to the processor, and,
determine a target position of the reference device in the medical image, acquired at a time when the respiratory cycle has been blocked, from the at least one locating element, positioned on the reference device, and from the X-ray detector,
determine a candidate position of the reference device from the at least one locating element positioned on the reference device, at a time when the respiratory cycle has again been blocked,
compare the candidate position and the target position,
when the candidate position is not within a predefined tolerance range with respect to the target position, repeating determine the candidate position and compare the target and candidate positions until the candidate position is within a predefined tolerance range with respect to the target position, and
estimate, from a predictive model of the respiratory cycle of the patient, a moment of blocking of breathing of the patient during the determination of the candidate position.
