Mass Screening of Multiple Abdominal Solid Organs Using Mobile Helical Computed Tomography Scanner—A Preliminary Report

Lung Cancer Screening by Helical Computed Tomography

Relationship between aortic calcification and stroke in a mass screening program using a mobile helical computed tomography unit.

BACKGROUND It is reported that there is a significant relationship between the calcification of the aortic arch detected by chest X-ray examination and stroke. However, the relationship between stroke and aortic calcification (AoC) detected during a mass screening using a mobile helical computed tomography (CT) unit remains unknown. METHODS AND RESULTS The study population consisted of 2,618 ...

Abdominal perfusion computed tomography.

The purpose of this article is to provide an up to date review on the spectrum of applications of perfusion computed tomography (CT) in the abdomen. New imaging techniques have been developed with the objective of obtaining a structural and functional analysis of different organs. Recently, perfusion CT has aroused the interest of many researchers who are studying the applicability of imaging m...

A reconstruction method for helical computed tomography

This paper presents a method for volumetric reconstruction from Helical Computerized Tomography (H-CT) data which are collected with a fan beam source. An interpretation of the HCT data in terms of the Axial Computerized Tomography (ACT) data is provided. This analysis indicates that the H-CT data for positive and negative detector angles can be combined to form periodically nonuniform hexagona...

Single click volumetric segmentation of abdominal organs in Computed Tomography images

Current segmentation techniques require user intervention to fine-tune thresholds and parameters, plot initial contours, refine seed placement, and engage in other optimization strategies. This can cause difficulties for physicians trying to use segmentation tools as they may not have the time or resources to overcome steep learning curves. In order to segment volumetric regions from sequential...
