Methods and systems for image synchronization

A method for controlling a system for performing image synchronization, the method comprising:

• using one or more imaging modalities to obtain imaging data using an imaging apparatus of the system;
• performing beam scanning, via a scanning mechanism of the system using a rotary motor of the system and a pullback motor of the system, of a catheter or probe of the system to obtain a beam position of the catheter or probe, the rotary motor operating to rotate the scanning mechanism, a part of the scanning mechanism, and/or the catheter or probe, and the pullback motor operating to control pullback of the catheter or probe;
• achieving image synchronization, via one or more processors of the system, by recording the beam position simultaneously or contemporaneously with the imaging data and enabling accurate spatial registration of the imaging data;
• controlling, or sending commands to, via the one or more processors of the system, a rotary motor controller of the system and a pullback motor controller of the system;
• and
• conditioning or controlling, via a synchronization processor of the one or more processors, first and second encoder signals before the synchronization processor interfaces with a data acquisition processor of the one or more processors such that each time a depth scan is acquired on the imaging data input, information from the first and second encoder signals is recorded for each of the rotary motor and the pullback motor to record an exact or approximate beam position for the depth scan, and the synchronization processor operates to use a single synchronization signal for the data acquisition processor to capture a position of the catheter or probe for each measured depth scan profile, wherein the system further includes the first encoder signal that operates to be available to the rotary motor controller and the second encoder signal that operates to be available to the pullback motor controller.

A non-transitory computer-readable storage medium storing at least one program that operates to cause one or more processors to execute a method for performing image synchronization for one or more imaging modalities of a system, the method comprising:

• using one or more imaging modalities to obtain imaging data using an imaging apparatus of the system;
• performing beam scanning, via a scanning mechanism of the system using a rotary motor of the system and a pullback motor of the system, of a catheter or probe of the system to obtain a beam position of the catheter or probe, the rotary motor operating to rotate the scanning mechanism, a part of the scanning mechanism, and/or the catheter or probe, and the pullback motor operating to control pullback of the catheter or probe;

• controlling, or sending commands to, via the one or more processors of the system, a rotary motor controller of the system and a pullback motor controller of the system;
