Purpose:To investigate and find out the best weight adaptive statistical iterative reconstruction(ASIR) algorithm and application of low kv(p)scan in thoracic aorta CTA experiment research.Method:A chest depth of 17cm of the thoracic aorta phantom was scanned with Discovery CT750 under the acquiescent parameters or factors of 120kv, 400mAs.Reconstruction was performed with different weightings of ASIR (10％—100％, step 10％), then the signal to noise ratio (SNR) and contrast to noise ratio (CNR) were calculated.

Several studies have shown that heavy metal filters with K edges in a diagnostic energy range reduced patientradiation dose without degrading image quality.However, increased exposure time was a probl
Purpose: Portable X-rays were traditionally done with the conventional portable X-ray unit with Computed Radiography system (conventional-CR combo), and off-site processing of the exposed Computed-Rad
Purpose: We have developed a computerized scheme for producing simulated low-dose CT images from real standard-dose CT images.The purpose of this study is to compare the simulated lowdose CT images an
Purpose: The medical radiation application is increased rapidly recent years;CT is particularly more than the rest of radiographies.A review of patient doses from CT examinations in Taiwan for 2012 ha
目的:影像医学技术的进步,使得X光医学影像由传统X光片方式进展至数字化,进步相对也推动着仪器的更新与带来病患的便利性.移动式X光机主要应用范围为无法离开病房区之患者,在检查部位主要以胸部X光占大部份.辅助器的使用主要增加影像质量与辅助放射师因技术不熟练度而造成的影像重照,近年来于技术方面的辅助器使用主要在于改善影像质量,提高病患安全为目标,本研究应用水平尺辅助器于移动式胸部X光摄影检查,可以有效的
