Disclosed are optical probes and methods for use of such probes. In one embodiment, an optical probe includes a housing that is sized and configured to be passed through a lumen having an inner diameter no greater than approximately 2 millimeters, and an internal optical system provided within the housing, the optical system being configured to capture images of a feature of interest associated with the lumen. In another embodiment, an optical probe includes a housing configured for passage through a narrow lumen, and an internal optical system provided within the housing that is configured to capture images of a feature of interest associated with the lumen, the optical system including axicon optics that form a focal line rather than a discrete focal point. In one embodiment, a method includes advancing an optical probe through the lumen to position the probe adjacent the feature of interest, and imaging the feature of interest across a depth of the feature of interest with invariance of resolution using an internal optical system of the probe.

In some embodiments, stress values for a diseased artery are obtained, stress ratios are determined from the obtained stress values, and a flow-structure interaction index is generated based upon the stress ratios as a function of a given plaque characteristic. In further embodiments, a plaque characteristic of a patient is determined, a patient's stress ratio is determined in relation to the flow-structure interaction index and the plaque characteristic, and the patient's stress ratio is compared to a critical stress ratio to determine whether the patient's stress ratio exceeds the critical stress ratio.

Disclosed are systems and methods for evaluating body vessels. Images of the vessel are captured, analyzing to generate a three-dimensional model of the vessel, and the data associated with the three-dimensional model is analyzed. In cases in which the vessel is a coronary artery, the vessel model can be analyzed to determine the vulnerability of plaques within the artery to rupture. In some embodiments, the images are optical coherence tomography images. In some embodiments, the images are captured with an optical catheter that includes a tracking device. In some embodiments, the analysis includes flow and/or structural analysis.

A strong magnetic field, for example in the range of 500-50,000 Gauss, is applied across a tundish feeding continuous casting machines. The magnetic field, substantially perpendicular to the principal direction of flow within the tundish, provides very even flow in the tundish, uniform residence time and minimizes vortexing. The application of the magnetic field increases the percentage of inclusion particles removed from the melt during its residence within the tundish.
