A dynamic model of CT scans for quantifying doubling time of ground glass opacities using histogram analysis

Math Biosci Eng. 2018 Oct 1;15(5):1203-1224. doi: 10.3934/mbe.2018055.

Abstract

We quantify a recent five-category CT histogram based classification of ground glass opacities using a dynamic mathematical model for the spatial-temporal evolution of malignant nodules. Our mathematical model takes the form of a spatially structured partial differential equation with a logistic crowding term. We present the results of extensive simulations and validate our model using patient data obtained from clinical CT images from patients with benign and malignant lesions.

Keywords: CT scan; Medical imaging; logistic partial differential equation.
