From: Piezoelectric needle sensor reveals mechanical heterogeneity in human thyroid tissue lesions
Experimental workflow during the typical STFN measurements and distribution of tissue stiffness heterogeneity observed for thyroid carcinoma and the healthy thyroid. Following a standard operating procedure, samples were first prepared by attachment and orientation into quadrants, using (a) biocompatible sample holders with calibrated grids as illustrated schematically in (b). (c) An inked patient sample measured using STFN. Samples were later processed for standard tissue histology.
