چکیده

In this paper, we propose a method to classify pulmonary artery and vein in chest X-ray CT images automatically. When a doctor discriminates between benign or malignant of lung tumors, kind of pulmonary blood vessels which are involved in tumors is very important. However there is no difference on CT values. So it is difficult to classify vessels based on CT values. Our method uses anatomical positional relations between bronchus and each vessel, and analyzes tree structure of vessels to generate appropriate vessels groups. We applied this method to three X-ray CT images. The experimental result showed that about 87% of pulmonary artery and vein were classified correctly.

Automated classification of pulmonary nodules through a retrospective analysis of conventional CT and two-phase PET images in patients undergoing biopsy

Objective(s): Positron emission tomography/computed tomography (PET/CT) examination is commonly used for the evaluation of pulmonary nodules since it provides both anatomical and functional information. However, given the dependence of this evaluation on physician’s subjective judgment, the results could be variable. The purpose of this study was to develop an automated scheme for the classific...

Application of 128-slice spiral CT combination scanning in the diagnosis of embolisms in pulmonary arteries and lower extremity veins

The aim of this study was to evaluate the significance of using multi-row spiral computed tomography (CT) to scan for pulmonary artery thrombosis and lower limb deep vein thrombosis (LVT) in patients with suspected LVT. A total of 110 patients underwent a contrast-enhanced spiral CT inspection of the pulmonary artery and lower extremity veins. Three-dimensional digital image processing, includi...

Carcinoma of the lung misinterpreted as pulmonary sequestration on contrast CT but correctly identified on FDG PET/CT.

The chest x-ray of a 68-year-old man with a history of cough with blood-tinged sputum showed an abnormality in the right lower lung. Contrast-enhanced CT favored pulmonary sequestration with a feeding artery from the right inferior phrenic artery and a drainage vein into the right pulmonary vein. He had shortness of breath and chest tightness, which prompted an FDG PET/CT study to evaluate the ...

Investigation of dosimetric characteristic of NIPAM polymer gel using x-ray CT

Introduction: Polymer gel dosimeters contain chemical materials sensitive to the radiation which are polymerized by the radiation as a function of absorbed dose. So information of spatial dose distribution can be extracted by imaging from irradiated gel. Among imaging techniques, computed tomography (CT) poses as an attractive method because of practical advantages such as acce...
