1. A device comprising:
one or more computer-readable media storing instructions; and
one or more processors that are in communication with the one or more computer-readable media and that, when executing the instructions, cooperate with the one or more computer-readable media to cause the device to perform operations that comprise:
obtaining first imaging data and first timestamps that correspond to the first imaging data, wherein the first imaging data include a first timing signal, and wherein the first timing signal, as included in the first imaging data, is encoded;
obtaining second imaging data and second timestamps that correspond to the second imaging data, wherein the second imaging data include a second timing signal, and wherein the second timing signal, as included in the second imaging data, is encoded;
demodulating the first imaging data to acquire the first timing signal as encoded in the first imaging data;
demodulating the second imaging data to acquire the second timing signal as encoded in the second imaging data; and
calculating a delay value based on the first timing signal as encoded in the first imaging data, the second timing signal as encoded in the second imaging data, the first timestamps, and the second timestamps, wherein calculating the delay value includes comparing a respective waveform of the first timing signal as encoded in the first imaging data with a respective waveform of the second timing signal as encoded in the second imaging data, wherein the respective waveform of the first timing signal is independent of any structure depicted in the first imaging data, and wherein the respective waveform of the second timing signal is independent of any structure depicted in the second imaging data.
