Abstract: In part, the invention relates to an image data collection system. The system can include an interferometer having a reference arm that includes a first optical fiber of length of L1 and a sample arm that includes a second optical fiber of length of L2 and a first rotary coupler configured to interface with an optical tomography imaging probe, wherein the rotary coupler is in optical communication with the sample arm. In one embodiment, L2 is greater than about 5 meters. The first optical fiber and the second optical fiber can both be disposed in a common protective sheath. In one embodiment, the system further includes an optical element configured to adjust the optical path length of the reference arm, wherein the optical element is in optical communication with the reference arm and wherein the optical element is transmissive or reflective.

Abstract: In part, the disclosure relates to computer-based methods, and systems suitable for evaluating a subject to determine the appropriate diagnostic tools for assessing coronary arteries. This can include assessing various blood pressure values during a resting state (without inducing hyperemia). These systems and methods can assess a patient and identify coronary dominance on per patient basis. In turn, this assessment can be used to recommend whether a resting index is appropriate or if another index such as FFR or others such be obtained diagnostic metric such as a pressure value-based ratio.
