The computer-assisted methods for measuring and tracking nodule volumes have the potential to improve precision for indicating of malignancy for indeterminate nodules. In this paper, we propose a semi-automatic geometric solitary pulmonary nodule (SPN) volume measurement algorithm for calculating the precise volume of indeterminate SPNs with low-dose CT (LDCT) images. The algorithm divided the SPN...
In this paper we present a method for developing a fully automated computer aided diagnosis (CAD) system to help radiologist in detecting and diagnosing micro-calcifications (MCCs) in digital format mammograms. One aim of the CAD system is to increase the effectiveness and efficiency of screening procedures by using computer. Another aim of the CAD is to extract and analyze the characteristics of...
As an important and necessary step in many medical image processing applications, contrast enhancement can amplify tiny anatomies, such as airways, vessels, lung nodules and pulmonary fissures in lung CT (computerized tomography) images. In this paper we describe a more useful contrast enhancement algorithm based on localized histogram equalization for low-dose CT images. This algorithm applies a...
