Summary

Midjourney, known for its AI image model, has announced a pivot to medical scanners with the new MidJourney Scanner. This device submerges a patient in a water tank, using a ring of ultrasound scanners and AI to reconstruct echoes into a 3D body image, offering ultrasound tomography similar to CT or MRI but without harmful radiation and completing in twenty seconds. However, the technology faces significant limitations, including ultrasound's inability to penetrate bone or air, restricting its utility for many organs like the brain or lungs. While it could potentially pioneer new low-risk screening applications, existing medical consensus often recommends against general whole-body screenings, such as those costing \$2,000 for an MRI, due to high rates of false positives and associated unnecessary interventions. The scanner's future utility largely depends on substantial advancements in AI for interpretation and overcoming physical barriers.

Key takeaway

For healthcare investors or AI product managers evaluating novel diagnostic technologies, critically assess claims of broad utility against established medical facts. The Midjourney Scanner illustrates how physical limitations and false positive risks can outweigh potential benefits, even with advanced AI. Prioritize solutions addressing specific, unmet diagnostic gaps. Focus on clear evidence of improved patient outcomes, rather than relying on future AI to overcome fundamental challenges.

Key insights

Midjourney's new ultrasound tomography scanner faces significant medical limitations and regulatory hurdles for broad diagnostic use.

Principles

• Ultrasound cannot penetrate bone or air, limiting its diagnostic scope.
• Early cancer detection via screening does not always improve outcomes.
• Whole-body screening often yields dangerous false positives.

Method

The Midjourney Scanner submerges a patient in a water tank, using ultrasound emitters and AI to reconstruct a 3D body image of the body.

In practice

• Could replace DEXA scans for body composition analysis.
• Potentially useful for specific breast cancer screening.
