Background:

Precise alignment of imaging and measuring components is crucial for accurate X-ray-based diagnostics and research.
Traditional alignment methods can be time-consuming and prone to inaccuracies.

Purpose of the Study:

To develop and present a straightforward, two-laser alignment approach for X-ray beam and component positioning.
To enhance the accuracy and convenience of aligning various components in X-ray systems.

Main Methods:

Utilized two lasers: one parallel to the component path from the source, and a second from the opposite direction.
Calibrated the second laser to coincide with the first, creating a visible X-ray beam path indicator.

Main Results:

Successfully established a visible alignment indicator for the incident X-ray beam.
Demonstrated convenient and accurate alignment of multiple components using the two-laser system.

Conclusions:

The presented two-laser method offers an effective solution for precise alignment in X-ray applications.
This technique simplifies and improves the accuracy of setting up imaging and measuring equipment relative to X-ray sources.
