Automated Analysis of the Distributions and Geometries of Blood Vessels on Retinal Fundus Images

We have developed a computer-aided diagnosis system to detect the abnormalities on retinal fundus images. In Japan, ophthalmologists usually detect hypertensive changes by identifying narrowing arteriolae with a focus on an irregularity. The purpose of this study is to develop an automated method for detecting narrowing arteriolae with a focus on an irregularity on retinal images. The blood ves...

Semi-automated tracking and continuous diameter monitoring of inferior vena cava in simulated and experimental ultrasound imaging

Assessment of respirophasic diameter fluctuations of the inferior vena cava (IVC) is detrimentally affected by its concomitant displacements. This study aims at presenting and validating a method to compensate for IVC movement artifacts while continuously measuring its diameter in an automated fashion (with minimal interaction with the user) from a longitudinal B-mode ultrasound (US) clip. Perf...

Peripheral Vessel Investigation For Routine Clinical Use

This paper is about computed tomography angiography based vessel exploration. Large image sequences of the lower extremities are investigated in a clinical environment. Two different approaches for peripheral vessel diagnosis dealing with stenosis and calcification detection are introduced. The paper presents an automated vessel-tracking tool for curved planar reformation. A user interactive se...

Autoregulation of Blood Flow: Vessel Diameter Changes in Response to Different Temperatures

Background: Autoregulation of blood flow is a marvelous phenomenon balanc- ing blood supply and tissue demand. Although many chemically-based explanations for this phenomenon have been proposed and some of them are commonly used today, biomechanical aspects of this phenomenon was neglected. The biomechanical aspect provides insights to us to model vessel diameter changes more precisely and comp...
