On the properties of the intensity-curvature measurement approaches: the classic-curvature and the intensity-curvature functional

Abstract

Objective: This paper expands on the basis of previous research confirming through empirical evidence both meaning and natureof the classic-curvature and the intensity-curvature functional images. Methods: Eleven subjects affected by human brain tumors were scanned using Magnetic Resonance Imaging (MRI). TwodimensionalMRI images were selected to study the subjects using the intensity-curvature measurement approaches called:classic-curvature and intensity-curvature functional. The bivariate cubic polynomial and the bivariate linear function were fittedto the MRI images in order to compute the classic-curvature and the intensity-curvature functional respectively. Results: This work shows one novelty related to the use of the two intensity-curvature measurement approaches when furtheringthe study of tumors detected with MRI. The novelty is the highlight of the accumulation of the contrast agent through the visuallyperceptible third dimension perpendicular to the imaging plane. Conclusions: The meaning and the nature of the aforementioned intensity-curvature measurement approaches is the capability tofilter the MRI.
