Visualization of B-scan transducer transverse cross-sectional beam patterns

Area of Science:

• Medical Imaging
• Biomedical Engineering
• Diagnostic Ultrasound

Background:

• Ultrasound transducer performance is critical for diagnostic image quality.
• Regular testing of clinical ultrasound equipment is essential for reliable diagnostics.
• Existing methods for transducer beam pattern analysis can be complex or require specialized environments.

Purpose of the Study:

• To develop a simple, user-friendly technique for assessing ultrasound transducer beam patterns.
• To enable clinical personnel to perform in-house transducer quality control.
• To evaluate the impact of equipment parameters on beam patterns and spatial resolution.

Main Methods:

• A novel technique to "fool" a B-scanner into imaging the transverse cross-sectional beam pattern.
• Application of the technique under normal clinical conditions of use.
• Demonstration of the effects of equipment parameters on beam pattern and image resolution.

Main Results:

• The developed technique is easily implementable by clinical staff.
• The method accurately measures transducer connector/acoustic axis misalignment.
• The technique effectively demonstrates the influence of equipment parameters on beam patterns and spatial resolution.

Conclusions:

• A practical and accurate method for in-house ultrasound transducer testing has been established.
• This technique facilitates routine quality control and performance verification of clinical ultrasound transducers.
• The findings support improved diagnostic accuracy through regular equipment assessment.
