What is the detector distance for over-table tubes?

The correct detector distance for over-table tubes is established at 30 cm above the table. This measurement is critical in radiography and fluoroscopy because it helps to optimize the exposure and the quality of the images while also ensuring patient safety.

This standardized distance allows for the efficient collection of X-ray data and works to reduce the potential for scatter radiation, which can negatively affect image clarity and increase radiation exposure to the patient. It also contributes to the proper alignment of the X-ray tube and detector with the area of interest, ensuring accurate imaging and diagnosis.

Understanding the importance of this distance is key for both patient safety and the effectiveness of fluoroscopic procedures. The focus on a specific distance is a practice rooted in ensuring consistent image quality and safety across various procedures in fluoroscopy.
