概括

过器 (AF) 没有改善束计算断层扫描 (CBCT) 图像对马的甲骨管/甲骨干. 较厚的AF改善了近道的图像质量,在马匹远端四肢成像中平衡了辐射暴露和诊断细节.

科学领域:

兽医辐射学兽医辐射学
马匹诊断成像技术马匹诊断成像技术
生物医学工程生物医学工程

背景情况:

形束计算断层扫描 (CBCT) 对于诊断马匹远端四肢损伤至关重要.
马类甲/甲的皮质骨细节在CBCT扫描中通常是有限的.
过器 (AF) 提高了人类医疗CBCT图像质量,并减少了辐射.

研究的目的:

评估AF对CBCT图像质量的影响.
为了确定马匹四肢CBCT的最佳成像参数.
为了评估图像质量和辐射剂量之间的权衡.

主要方法:

用移动CBCT单元扫描马匹尸体的四肢.
使用了可变管电流 (10-100 mA) 和AF (13-25 mm).
图像质量由两位专家使用视觉分级尺度进行评估.

主要成果:

较高的管道电流通常会改善图像质量.
没有AF改善了手指后/手足后区域的图像质量.
更厚的AF (19-25毫米) 提高了近道法朗克斯的图像质量,而不会增加管道电流.

结论:

对于马类甲/甲,没有AF的50-64mA提供最佳的图像质量和辐射平衡.
对于马类近道,50 mA与19-25 mm AF产生最好的图像质量.
优化的CBCT参数可以改善马匹远端四肢骨折的诊断.

关键词:

诊断图像质量保证诊断图像质量保障过器的过器是一个过器.裂裂是一个裂.马的马,马的马,马的马,马的马.管道当前的电流是一个管道.

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
