Abstract

PURPOSE

An anti-scatter grid is often used in X-ray radiography to reduce the scattered X-rays generated from the patient. However, the presence of a grid means the patient dose subsequently increases. Recently,severalmanufacturers have developedsoftwarethat is capable of correctingfor scattered X-rays withouttheuse ofa conventional grid. This scoping review aims to systematically map the research assessing scattering correction software and to identify any existing knowledge gaps.

METHODS

This scoping review involved conducting a systematic search in PubMed, Scopus, and Web of science to reveal studies that were relevant to the research question. Articles published between 01.01.2000 and 31.12.2021 examining X-ray scatter correction software for X-ray imaging were included. A part of the PRISMA model and PICO framework were utilised to establish eligibility criteria. A structured summary table was utilised to extract data from the selected articles.

RESULTS

In this scoping review, 20 years of literature in X-ray conventional radiography. 11 articles were included in the data synthesis. The study populations of the included studies were varied: patients, image quality phantoms and anatomical phantoms. The clinical applications of X-ray scatter correction software were found to be limited to specific body parts (cervical spine, chest, shoulder, lumbar spine, hip and pelvis). The scatter correction software appears to be effective in terms of image quality and in reducing the radiation dose. However, the conventional grid still provides a higher image quality.

CONCLUSIONS

X-ray scatter correction software can be effective and provides potentialbenefits for some circumstances or clinical scenarios.

摘要

目的

在 X 射线摄影中，通常使用防散射栅格来减少来自患者的散射 X 射线。然而，栅格的存在意味着患者剂量随后会增加。最近，一些制造商已经开发出能够在不使用传统栅格的情况下纠正散射 X 射线的软件。本范围综述旨在系统地绘制评估散射校正软件的研究，并确定任何现有知识差距。

方法

本范围综述包括在 PubMed、Scopus 和 Web of Science 中进行系统搜索，以揭示与研究问题相关的研究。纳入了发表于 2000 年 1 月 1 日至 2021 年 12 月 31 日之间、检查 X 射线散射校正软件用于 X 射线成像的文章。利用 PRISMA 模型和 PICO 框架的一部分来确定纳入标准。利用结构化总结表从选定文章中提取数据。

结果

在这项范围综述中，对 X 射线常规放射摄影 20 年来的文献进行了研究。有 11 篇文章被纳入数据综合分析。纳入研究的研究人群各不相同：患者、图像质量体模和解剖体模。X 射线散射校正软件的临床应用仅限于特定身体部位（颈椎、胸部、肩部、腰椎、臀部和骨盆）。散射校正软件在图像质量和降低辐射剂量方面似乎是有效的。然而，传统栅格仍然提供更高的图像质量。
