In 3D cone-beam Industrial Computed Tomography (ICT), in addition to the case which the inspected workpiece is longer than the detector, it is common that the diameter of the detected workpiece is bigger than the width of the detector. The helical trajectory can solve the problem of long object scan, not the problem of big object scan. In this paper, a scan mode and reconstruction method is dis...

An 18-year-old male patient with Hodgkin's lymphoma stage IVB (HL-IVB), is presented. On a follow-up examination a splenic ultrasound scan showed the presence of multiple intense nodules. The gallium-67 citrate, single photon emission tomography scan was negative, while positron emission tomography/computerized tomography (PET/CT) scan with fluoro-18-fluordeoxyglucose was strongly positive. Mas...

The relationship between laboratory and chest computed tomography scan findings severity of COVID-19 cases: a single center study

INTRODUCTION Although the importance of the bronchial arteries is evident in modern day thoracic surgery, the significance of their communications with coronary arteries has yet to be appreciated, especially in cases of heart-lung transplantation and aortic aneurysm repair. We conducted a study to demonstrate the coronary-bronchial anastomotic routes in a porcine model using angiography and com...

Abstract Brucellosis is one of the most important zoonosis. It causes significant economic and medical problems in countries throughout the world, including Iran. According to the available literature, brucellosis rarely causes intracranial space-occupying lesions. In this case study, we reported an intracranial mass in a 52-year-old male who were affected with brucellosis. The patient was ref...

In order to confirm the accuracy of ECT (emission computed tomography) scanning imaging in the diagnosis of lung histoplasmosis is higher than CT (computed tomography) scan. We retrospect a lung histoplasmosis patient, he was examined by the CT scan and ECT scanning, respectively. Results showed that lung cancer for CT diagnosis and large benign lesions for F-FDG (F-fluorodeoxyglucose) ECT diag...

The availability of medical aids in adequate quantities is very much needed to assist the work staff dealing with large number Covid patients. Artificial Intelligence (AI) Deep Learning (DL) method, especially Convolution Neural Network (CNN), able diagnose Chest X-ray images generated by Computer Tomography Scanner (C.T. Scan) against certain diseases (Covid). Inception Resnet Version 2 archit...

Lung infection or sickness is one of the most common acute ailments in humans. Pneumonia lung infections, and annual global mortality rate from untreated pneumonia increasing. Because its rapid spread, caused by Coronavirus Disease (COVID-19) has emerged as a danger December 2019. At clinical level, COVID-19 frequently measured using Computed Tomography Scan Slice (CTS) Chest X-ray. The goal th...
