The characteristics of diamond detector and its performance in small photon beams

Paya Thantaranont (Chulalongkorn University, 2008)

An ideal radiation detector for small photon beam should have the properties of high radiation sensitivity, high spatial resolution, constant response and soft tissue equivalent. The objectives of this study were to ...
The correlation of effective dose from calculation method and the patient skin dose measurement using solid state detector for abdominal computed tomography examination

Piangtawan Kanjana (Chulalongkorn University, 2009)

Computed Tomography (CT) is a diagnostic imaging modality resulting in higher patient dose than other radiological procedures. As the rapid growing of CT, the patient dose from CT examination is questioned and needed to ...
The determination of patient dose from [supercript 18]F-FDG PET/CT examinations

Kitiwat Khamwan (Chulalongkorn University, 2007)

The development of PET/CT scan has received great attention in the medical diagnostic study.However, whole-body PET/CT examinations increase patient exposure compared to an individual CT or PET examination. The purpose of ...
Effect of 12 weeks treadmill training with whole body vibration on bone markers in postmenopausal Thai women

Wisaneeya Siwapituk (Chulalongkorn University, 2009)

Objectives: To study effects of 12 weeks treadmill training with whole body vibration on bone markers in postmenopausal Thai women. Materials and methods: The subjects were healthy Thai women with postmenopause at least 5 ...
Optimization of abdomen Multiplanar Reformation (MPR) with isotropic data sets aquired for 16-Detector CT scanner

Hataipat Jantawong (Chulalongkorn University, 2008)

The technology of 16-detector CT scanner enables the submillimeter section acquisition which in turn yields the isotropic data set that provides the generation of MPR image with the similar image quality to that in the ...
Patient radiation dose and image quality in simple radiographic projections using computed radiography (CR) system : comparison the results between before and after the training

Sunee Lumlertdacha (Chulalongkorn University, 2008)

The purpose of this study is to determine the patient dose in clinical setting from the CR system while maintaining the image quality and the retake rate reduction. The data were collected from patients examined at two ...
Patient skin dose determined by radiochromic film and dap meter method in cardiac catheterization and interventional radiology

Choocheep Kumkrua (Chulalongkorn University, 2004)

The patient dosimetry in this study was determined by radiochromic film and Dose Area Product (DAP) methods. The dose measurement was carried out from 64 adult patients who underwent the interventional radiology examinations ...
Performance characteristics of Automatic Exposure Control (AEC) system for computed tomography (CT) using phantom study

Supannee Pasongchun (Chulalongkorn UNiversity, 2008)

The number of CT examinations has increased as the growing number of the installed scanners. This resulted in the increased patient dose from the CT scan when compared to other radiographic examinations. In order to optimize ...
The study of computed tomography dose profile width using computed radiography imaging plate

Sirapath Sirarojnkul (Chulalongkorn University, 2008)

The quality control of the CT scanner is usually performed by using the film for the dose profile, but film processing is becoming less available in department of radiology. The purpose of this study is to measure the ...
