A radial endobronchial ultrasound system providing localization of visualized lung lesions or nodules in the airways of a patient is provided herein. The system has three, main components: a guide sheath with a distal end, a flexible bronchoscope with a tip, and a radial endobronchial ultrasound probe. The guide sheath directs insertion of the bronchoscope into the patient, with the tip of the bronchoscope extending beyond the distal end of the guide sheath. The bronchoscope has an echogenic discrete marker formed inside and proximate its tip and a working channel configured to include and direct the probe. The probe is configured for insertion into the airways of the patient where the probe rotates to capture a 360-degree circumferential image perpendicular to the probe itself. The echogenic discrete marker on the bronchoscope provides a reference point for localization of the lung lesions or nodules visualized by the image.

A method for adapting, per cardiac cycle, the parameters governing interpolation of varying and non-interpolation of fixed fractions of each individual cardiac cycle is provided. A time series of data values associated with a cardiac cycle is received, and the time series is scaled to a reference cardiac cycle, wherein the scaling includes applying a model to the time series to generate a scaled time series of data values associated with the first cardiac cycle. The model is trained using the scaled time series.

Disclosed herein is a non-invasive system for determining tissue composition. The system comprises an imaging system with a non-invasive probe, a signal analyzer, and a correlation processor. The probe includes active imaging components for emitting energy and collecting imaging data including reflected signals from an object of interest. The signal analyzer analyzes the imaging data and determines one or more signal properties from the reflected signals. The correlation processor then associates the one or more signal properties to pre-determined tissue signal properties of different tissue components through a pattern recognition technique wherein the pre-determined tissue signal properties are embodied in a database, and identifies a tissue component of the object based on the pattern recognition technique.
