3D Ultrasound Computer Tomography (USCT): A Safer, Cost-Effective Breakthrough in Breast Cancer Screening

Developed by researchers at the Karlsruhe Institute of Technology (KIT), 3D Ultrasound Computer Tomography (USCT) is an innovative imaging technology designed for early breast cancer detection. This cutting-edge method offers a radiation-free, patient-friendly alternative to traditional X-ray mammography, CT scans, or MRI, combining affordability with advanced diagnostic capabilities.

Why USCT Stands Out

• No Radiation Exposure: Unlike X-ray-based methods, USCT uses harmless ultrasound waves, ensuring patient safety.
• Cost-Effective: Significantly more affordable than MRI, making advanced breast imaging accessible to broader populations.
• High Precision: Engineered to detect anomalies at early stages, improving treatment outcomes.

How It Works

The KIT-developed USCT system features a hemispherical imaging chamber filled with water, housing approximately 2,000 ultrasound transceivers. These transceivers are organized into groups of 18, each controlled by custom USCT9C ASIC chips designed by KIT-ADL.

Key Features of USCT9C ASIC

• High-Performance ASIC Drivers: Each chip integrates nine high-voltage drivers capable of generating 120V output signals (5MHz bandwidth) to power transceivers.
• Advanced Signal Reception: A three-stage, low-noise amplifier system allows configurable feedback for wide-band (0.1–5MHz) or narrow-band signal amplification, with adjustable frequencies and gain.
• Ultra-Low Noise: Simulations confirm an exceptional input-referred noise level of below 10µV, ensuring high signal clarity.

Results

The first full-scale 3D USCT prototype has already been constructed and validated, demonstrating its potential to revolutionize breast cancer screening. By merging safety, affordability, and precision, this technology paves the way for a new possibility in preventive healthcare.
