Highlights from the Podcast
Gavin and ASNT’s Content Strategist Haley Cowans discuss advanced ultrasonic methods like Full Matrix Capture (FMC) and Total Focusing Method (TFM).
These techniques are improving inspection speed and image quality. Gavin explains how hardware and software advancements, like AI and GPUs, are enabling real-time data processing. These updates are changing the game for both manual and automated inspections.
One exciting development? Phase-coherence techniques that enhance signal-to-noise ratios and near-surface resolution, helping overcome challenges with complex materials.
Key Moments from the Conversation
In ultrasonic testing, we hear a lot about phased array. Can you share some of the latest ultrasound imaging technologies?
“Full Matrix Capture is one of the newer techniques. It’s similar to phased array but collects raw data differently. Afterward, we use the Total Focusing Method for reconstruction, resulting in higher-resolution imaging.”
How has technology improved in terms of data capture and processing?
“Both have progressed. Methods like Full Matrix Capture allow us to move data to high-end computers for quick processing—thanks to advancements like Nvidia GPUs. This enables fast, high-quality imaging for both manual and automated inspections.”
What challenges are these techniques helping to address?
“Materials with complex grain structures can create noise, making it hard to interpret results. Phase coherence is showing promise in improving signal-to-noise ratios and near-surface resolution, even in tough applications.”
Why It’s Important ?
These advancements aren’t just technical upgrades, they’re making inspections faster and more reliable across industries.
Whether it’s manufacturing or infrastructure, high-speed, high-quality imaging is driving better efficiency and safety.
