[Operating mock-up of a scintillation gamma chamber]

Area of Science:

• Medical physics
• Nuclear medicine imaging

Background:

• Development of medical imaging devices is crucial for diagnostics.
• Availability of domestically produced components can reduce reliance on foreign imports.

Purpose of the Study:

• To design and evaluate an operating model of a gamma-chamber.
• To assess the performance of a domestically manufactured gamma-chamber.

Main Methods:

• Construction of an operating model using Soviet-industry devices, components, and materials.
• Comparison of the model's basic parameters with foreign gamma-chambers.
• Performance evaluation through phantom tests, clinical investigations of the thyroid, and tests with technetium-99m sources.

Main Results:

• The designed gamma-chamber model's parameters are comparable to widely used foreign models.
• Satisfactory performance was demonstrated in phantom tests.
• Clinical investigations of the thyroid and trial tests with technetium-99m sources yielded satisfactory results.

Conclusions:

• A functional gamma-chamber model can be successfully constructed using Soviet-era industrial components.
• The developed device meets performance standards for thyroid imaging and radioisotope source testing.
