Usability

Butterfly iQ/iQ+ Ultrasound System

Butterfly iQ/iQ+ is designed for broad accessibility and ease of use, connecting to standard mobile devices (iOS/Android) and featuring a single probe for whole-body imaging, making it highly portable and adaptable for various clinical settings. User testimonials highlight its intuitive app interface and immediate readiness for scanning. Koios DS for Breast, while integrated into existing PACS workflows, is a specialized decision support tool for radiologists, implying a more focused user base and integration into a professional imaging environment rather than broad point-of-care use.

Clinical Value

Koios DS for Breast

Koios DS for Breast is an FDA-cleared AI-powered clinical decision support software specifically designed to improve the accuracy and efficiency of breast cancer diagnosis from ultrasound images. Studies have shown it can significantly improve diagnostic accuracy, reduce inter- and intra-observer variability, increase cancer detection rates, and potentially reduce unnecessary benign biopsies. While Butterfly iQ/iQ+ offers AI-powered imaging tools and has a growing body of evidence for its diagnostic utility across various applications, its primary value lies in democratizing access to ultrasound imaging rather than specialized diagnostic accuracy improvements for a specific condition like breast cancer.

Pricing & Value

Butterfly iQ/iQ+ Ultrasound System

Butterfly iQ/iQ+ has a transparent pricing model with a device purchase cost and a mandatory annual subscription, making the overall cost clear to potential buyers. Its affordability compared to traditional ultrasound systems is a key value proposition, aiming to make high-quality ultrasound more accessible. Koios DS for Breast uses an annual subscription model tailored to customer size, based on the number of analyses and/or users, which is less transparent without direct engagement with the vendor. While both offer value, Butterfly iQ/iQ+ provides a complete imaging system at a more accessible price point.

Enterprise Readiness
