MUT offers safe and comfortable 3D diagnostic imaging for the early and reliable detection of breast cancer.

Advantages of MUT over X-Ray Mammography

• Higher sensitivity and specificity
• Non-invasive tissue-differentiation capability
• Safer (non-ionizing) & frequently repeatable
• All-subject (dense and implanted breasts)
• More comfortable (no compression needed)
• 3-D fixed-coordinate system for precise registration

Key Technical Innovations of MUT

1. Specially designed coded pulse sequences
2. Small ultrasonic transducers in transmission mode
3. Multi-band attenuation & dispersion at each voxel
4. Fusion of multiple attributes for tissue characterization

The unique lesion differentiation capability of MT relies on proper fusion of refractive and frequency-dependent attenuation & dispersion attributes at each voxel of the multimodal MUT images.

This capability has been clinically validated in 134 volunteers so far, achieving sensitivity >97% and specificity >98%.
