dr摄影的基本流程

英文回答：

DR Imaging Basic Process.

DR (Digital Radiography) imaging involves the following

basic steps:

1. Patient Positioning: The patient is positioned on

the DR table or upright stand, depending on the body part

being imaged.

2. Collimation: The X-ray beam is collimated to the

area of interest to reduce scatter radiation and improve

image quality.

3. Exposure: The X-ray source is activated, and the

detector captures the X-rays passing through the patient.

4. Image Acquisition: The detector converts the X-rays

into an electrical signal, which is then digitized and

processed to create the digital image.

5. Post-Processing: The digital image undergoes post-

processing to adjust contrast, brightness, and other

parameters to optimize its diagnostic value.

6. Image Storage and Viewing: The digital image is

stored on a computer system and can be viewed on a monitor

or printed for hard copy.

DR成像基本流程。

DR（数字放射成像）成像包括以下基本步骤：

1. 患者定位，根据要成像的身体部位将患者放置在DR桌子或

立式支架上。

2. 准直，X线束被准直到感兴趣的区域，以减少散射辐射并提

高图像质量。

3. 曝光，激活X射线源，探测器捕获穿过患者的X射线。

4. 图像获取，探测器将X射线转换为电信号，然后将其数字化

并处理以创建数字图像。

5. 后处理，数字图像经过后处理以调整对比度、亮度和其他参

数，以优化其诊断价值。

6. 图像存储和查看，数字图像存储在计算机系统中，可以在显

示器上查看或打印成硬拷贝。
