The adverse effects of ionizing radiation are well known among researchers today. However, is commonly used for diagnostic purposes in many medical imaging techniques. One the most important devices computed tomography (CT). It vital to determine doses, ensure patient safety, and minimize potential health risks.This study aims doses parotid glands spinal cord (C1-C2) region during (CT) brain imaging. To achieve this goal, exposure these areas different levels was simulated measured. This...

The segmentation of the liver is a difficult process due to changes in shape, border, and density that occur each section computed tomography (CT) images. In this study, Adding Inception Module-Unet (AIM-Unet) model, which hybridization convolutional neural networks-based Unet models, proposed for computer-assisted automatic tumors from CT scans abdomen. Experimental studies were carried out on four different image datasets, one was prepared study three open (CHAOS, LIST, 3DIRCADb). results...

This study investigates the radiation dose to oral mucosal tissues during C-arm fluoroscopy imaging using an Alderson Rando phantom and thermoluminescent dosimeters (TLD-100) for precise measurements. The aim is assess potential risks patients healthcare personnel exposed ionising these procedures. phantom, a human-equivalent model, was utilized simulate exposure in controlled environment. TLD-100 were strategically positioned 6th section of at intervals 0.5, 1, 2, 4, 8 minutes. experiments...

Objectives: This study aims to investigate the effect of full- and half-rotation angles on patient radiation dose quantitative image quality in CBCT imaging head neck region. Methods: A total 67 TLDs were used for dosimetry 16 different regions slices anthropometric phantom. The Hyperion X9 Pro (MyRay, Cefla, Imola, Italy) device was with a 90 kV pulsed beam 13x16e FOV size. Two separate modes (Regular 360 0 Quick 180 0) tested, mA determined by software. Effective doses (EDs) calculated...

Today, respiratory movement can be monitored and recorded with different methods during a simulation on four-dimensional (4D) computed tomography (CT) device to used in radiotherapy planning. A synchronized monitoring system (RPM) an externally equipped is one of these methods. Another method create 4D images the patient's breathing phases without need for extra equipment, anatomy-based software program integrated into CT device. Our aim compare RPM (Deviceless) which are two tracking moving...

Abstract Fluoroscopic examinations like Endoscopic Retrograde Cholangiopancreatography (ERCP) and Percutaneous Transhepatic Cholangiography (PTC) are fundamental in diagnosing treating hepatobiliary diseases. However, these procedures expose patients to significant radiation, highlighting the need for a detailed assessment of radiation doses received by critical organs. The study’s primary objective is determine experimental organs undergoing procedures. This study utilized an Alderson RANDO...
