[Basic research for development of pinhole camera using a Geiger Mueller counter].

Area of Science:

• Medical Physics
• Radiation Detection

Context:

• X-ray imaging is crucial in medical diagnosis.
• Visualizing scattered X-ray distribution aids in understanding image formation and quality.
• Current detectors have limitations in specific applications.

Purpose:

• To evaluate the feasibility of using a Geiger-Muller (GM) counter as an X-ray detector in a pinhole camera system.
• To develop and test an apparatus for two-dimensional scanning with a GM counter.
• To compare GM counter imaging performance with a standard phosphor plate detector.

Summary:

• A system was developed using industrial actuators to move a Geiger-Muller (GM) counter for two-dimensional X-ray detection.
• Scattered X-rays from a phantom were measured using the GM counter system and compared to phosphor plate measurements.
• The GM counter demonstrated capability in detecting low count-rate radiation, though achieving high-resolution 2D images requires further research.

Impact:

• This study proposes the GM counter as a potential complementary detector for X-ray imaging applications.
• Findings contribute to exploring novel detector technologies for enhanced X-ray visualization.
• The research may inform future developments in radiation detection for diagnostic imaging.
