Bone fractal analysis

Current Osteoporosis Reports, 2004
Fractal analysis is a quantitative method used to evaluate complex anatomic findings in their elementary component. Its application to biologic images, particularly to cancellous bones, has been well practiced within the past few years. The aims of these applications are to assess changes in bone and the loss of spongious architecture, indicate bone ...

Fractal Analysis in Human Pathology

Annals of the New York Academy of Sciences, 1999
.Living structures may be described as being in a self-organizing, fluctuating steady-state far from equilibrium. 1 Self-organization and a state far from equilibrium are characteristics of chaotic structures. Chaotic structures present fractal geometry, so is not too astonishing that the branching pattern of the airways in the lung or the arterial ...

Minkowski functional characterization and fractal analysis of surfaces of titanium nitride films

Materials Research Express, 2019
The aim of this study is to gain a deeper understanding of the micromorphology characteristics of thin titanium nitride (TiN) films sputtered on glass substrates by using ion beam sputtering (IBS).

Application of fractal analysis in hyperparathyroidism

Dentomaxillofacial Radiology, 2009
Primary hyperparathyroidism (HPT) is a condition caused by an overproduction of parathormone, in excess of the amount required by the body. Its most common cause is a parathyroid gland adenoma and parathyroidectomy is currently the only curative treatment for primary HPT. We present a case history of a 65-year-old patient who was diagnosed with primary

Fractals and the analysis of growth paths

Bulletin of Mathematical Biology, 1985
A simple practical method exists for classifying and comparing planar curves composed of connected line segments. This method assigns, a single numberD, the fractal dimension, to each curve.D=log(n)/[log(n)+log(d/L)], where:n is the number of line segments,L is the total length of the line segments, andd is the planar diameter of the curve (the ...
