研究目的:

儿童对X射线辐射剂量较成人更为敏感,准直功能可以减少儿童患者接受的曝光剂量,提高图像质量,是临床儿童X线摄片流程中不可或缺的步骤。西门子医疗开发了一种基于3D相机获取受检者身体厚度信息进行自动准直的功能,设置准确照射野,有助于简化操作流程。  

Objectives of Study:

Children are more sensitive to X-ray radiation doses than adults. The collimation function can reduce the exposure dose received by pediatric patients and improve image quality, making it an indispensable step in the clinical pediatric X-ray imaging process. Siemens Healthineers has developed an automatic collimation function based on 3D camera technology to acquire body thickness information of the examinee, enabling accurate setting of the irradiation field and helping to streamline the operational workflow

Outcome:

Intersection over Union, IoU; Border distance

Type:

Primary indicator

测量时间点:

实时

测量方法:

每例受检患者完成摆位后,3D相机获取患者身体厚度信息,在西门子医疗工作电脑上自动生成针对该次检查的光圈大小。将此光圈大小与对应X线图像对比,验证该算法准确性。

Measure time point of outcome:

Real time

Measure method:

The body thickness of each subject is acquired by 3D camera after positioning com-pleted during each x-ray examination. The collimator size is automatically generated in the working computer. Compare this collimator size with the corresponding x-ray image to validate the algorithm.
