Abstract
Aspects described herein disclose devices, systems, and methods for use in contexts such as minimally invasive surgery (MIS). Methods of use of radio frequency (RF) techniques for improved nerve detection in association with an ultrasound detection system are described. The methods include the use of RF echoes in the detection of tissue dependent features. The methods also include use of an RF classifier to reduce false positives. System dependent features are accounted for through use of a calibration spectrum or through non-parametric model estimation using machine learning.
