Simplified Wide-Range Ultrasonic Measurements Using the Sensor Three-Dimensional System.

Area of Science:

• Medical Imaging
• Biomedical Engineering
• Diagnostic Ultrasound

Background:

• Magnetic Resonance Imaging (MRI) systems are valuable for medical imaging but can be large and costly.
• Accurate, wide-area scanning is crucial for assessing large pathologies like huge myomas.
• Developing compact, versatile imaging devices is an ongoing challenge in medical diagnostics.

Purpose of the Study:

• To develop a simplified, compact, three-dimensional (3D) ultrasonic device for wide-area scanning.
• To enable freehand scanning with precise transducer positioning for volumetric data acquisition.
• To assess the utility of the developed system for objective understanding and follow-up measurements of huge tumors.

Main Methods:

• A simplified 3D ultrasonic device was engineered.
• Freehand scanning was performed using a magnetic sensor unit to track transducer position.
• Volume data was acquired over a wide range.
• The system was applied to a clinical case involving a huge myoma.

Main Results:

• The developed ultrasonic device successfully scanned a wide area and performed measurements.
• The system demonstrated a more compact form factor compared to MRI systems.
• The device enabled measurement of random cross-sections by acquiring volume data.
• Successful application to a case with a huge myoma was achieved.

Conclusions:

• The simplified 3D ultrasonic system provides a compact and versatile alternative for medical imaging.
• The system supports objective pathological understanding and follow-up tumor diameter determination at arbitrary cross-sections.
• This technology shows promise for applications similar to computed tomography (CT) and MRI systems in tumor assessment.
