摘要
在这项工作中,利用回收的铅片作为辐射吸收元件,制作了一个开放式限束装置,包括一个与口腔内牙科 X 射线装置耦合的矩形准直器。准直器设计为三维打印,并使用 Spektr 3.0 软件计算了吸收多余辐射所需的铅片数量。当使用四层再生铅片时,矩形准直器可将患者的辐射剂量减少 65%(当使用八层或更多铅片时,辐射剂量减少 70%,达到饱和)。矩形准直器不会对放射图像的质量产生负面影响,是一种可用于 3D 打印的开放式设计,可使用牙医容易获得的材料制造,便于在临床实践中使用,并减少患者接触电离辐射的机会。
Development of an open project rectangular collimator for use with intraoral dental X-ray unit.
In this work, an open beam-limiting device, consisting of a rectangular collimator to be coupled to an intraoral dental X-ray device, was made using recycled lead sheets as a radiation-absorbing element. The collimator was designed for 3D printing, and using Spektr 3.0 software, the number of lead sheets needed to absorb excess radiation was calculated. The rectangular collimator reduced the radiation dose to patients by 65% when using four layers of recycled lead sheets (saturating with a 70% reduction in radiation dose at the limit of eight or more sheets of lead). The rectangular collimator does not negatively impact the quality of the radiological image, is available as an open design for 3D printing, and can be built with materials that are easily accessible to the dentist, facilitating its use in clinical practice and reducing the patient's exposure to ionizing radiation.
期刊介绍:
The purpose of the journal Radiological Physics and Technology is to provide a forum for sharing new knowledge related to research and development in radiological science and technology, including medical physics and radiological technology in diagnostic radiology, nuclear medicine, and radiation therapy among many other radiological disciplines, as well as to contribute to progress and improvement in medical practice and patient health care.
