Usability

Butterfly iQ3 Ultrasound System

Butterfly iQ3 is designed for ease of use and portability, connecting to a smartphone or tablet with a user-friendly interface. It features a single probe for whole-body imaging, reducing the need to swap probes, and has configurable buttons for intuitive operation. Viz CTP, while accessible via mobile, is a software solution for analyzing CT perfusion images, which inherently involves a more complex workflow than a point-of-care ultrasound device.

Clinical Value

Butterfly iQ3 Ultrasound System

Butterfly iQ3 offers whole-body imaging with a single probe, supporting over 20 clinical applications and featuring AI-powered tools for enhanced diagnostic confidence across various specialties. Viz CTP provides AI-powered disease detection and intelligent care coordination for neurovascular conditions, with over 50 FDA-cleared algorithms, but a recent study indicated it detected fewer medium vessel occlusions compared to another AI software.

Pricing & Value

Butterfly iQ3 Ultrasound System

The Butterfly iQ3 has a transparent pricing model with a clear device cost and annual subscription tiers. Viz CTP uses a subscription model with annual fees based on the number of algorithms and population size, which is less transparent and potentially more variable for budgeting. While the iQ3 has an upfront cost for the probe, its single probe technology replaces multiple traditional probes, offering versatility and cost-effectiveness.

Enterprise Readiness

Tie

Both tools demonstrate enterprise readiness through HIPAA compliance, FDA clearance, and integration capabilities. Butterfly iQ3 connects to Butterfly Cloud with DICOM connector for EMR/PACS integration, and offers enterprise bundles with training. Viz CTP is a cloud-native solution that integrates with PACS and EHRs and offers a full stack communications platform for care coordination.

Innovation

Butterfly iQ3 Ultrasound System

Butterfly iQ3 leverages advanced Ultrasound-on-Chipu2122 technology, replacing traditional piezoelectric crystals with a semiconductor-based array for whole-body imaging with a single probe. It also features AI-powered imaging tools like iQ Sliceu2122 and iQ Fanu2122 for advanced 3D capabilities. Viz CTP focuses on AI-powered disease detection and intelligent care coordination with numerous FDA-cleared algorithms, but its core technology is image analysis rather than a novel hardware approach.

Support & Docs

Tie

Both companies offer comprehensive support and documentation. Butterfly Network provides user manuals, a knowledge base, and direct support via email, along with educational resources like Butterfly Academy. Viz.ai also offers a knowledge base with common questions, troubleshooting guides, and contact information for support.
