Butterfly iQ3 vs Suresult D3Ultra In Detail

Butterfly Network has been around since 2011, gaining recognition for its revolutionary Ultrasound-on-Chip® technology that makes handheld ultrasound more accessible and multifunctional. The iQ3 (2024) is their third-generation device with an emphasis on AI integration.

Suresult is a newer but rapidly growing player in the handheld ultrasound market from China. The company focuses on emphasizing affordability and versatility with a wide range of handheld ultrasound machines. D3Ultra is their flagship model with tri-mode probes. 

A. Imaging Performance & Depth Penetration

The Suresult D3Ultra is built on traditional piezoelectric crystal technology equipped with a triple-array probe—curved and phased on one end, paired with a linear probe on the other end of the same machine. Its frequency range spans 3.5–10 MHz, selected automatically among the three probe types depending on the scan’s depth requirements.

• A standout feature is its smooth Time Gain Compensation (TGC), which allows users to finely adjust brightness across different tissue depths. This makes the D3Ultra highly effective for situations where both superficial and deep structures need to be evaluated in the same session. 
• In practice, it performs well across musculoskeletal, vascular, nerve, cardiac function, and pelvic imaging.

The Butterfly iQ3 leverages its proprietary Ultrasound-on-Chip® technology, which uses capacitive micromachined ultrasonic transducers (CMUTs). This enables one probe to function across linear, convex, and phased modes seamlessly. This operates between 1–10 MHz with penetration up to 30 cm, and it provides convenience for multi-setting use without needing additional hardware. 

• IQ3 shines in bedside assessments such as jugular venous pressure scans, pleural effusions, hydronephrosis, and lung ultrasound. 
• While Butterfly does include TGC adjustments, they are not as finely tuned as the D3Ultra’s, giving the latter an edge in nuanced control.

B. Thermal Performance & Ergonomics

The D3Ultra has a slimmer form factor at 156 × 65 × 20 mm, a lighter weight of 263 g, and fully wireless operation. 

• Its balanced design reduces wrist strain during long scanning sessions, making it particularly comfortable in intensive care settings or during extended cardiac exams that require maneuvering between ribs. 
• The slim build also helps in tight ICU bays and sterile environments where movement is restricted. It’s powered by a wireless rechargeable battery that gives 2 hours of scan time on a full charge.

The Butterfly iQ3, in contrast, measures 152 × 52 × 37 mm and weighs 300 g, which makes it slightly thicker. 

• It requires a wired connection to pair with a smartphone or tablet for data control, and is powered by an internal battery that also supports about 2 hours of scanning per charge.
• One recurring issue with the Butterfly line has been thermal performance. Earlier generations had well-documented overheating problems, which even led to a recall. While the iQ3 shows significant improvement, reports of overheating in clinical use are still occasionally noted.

The D3Ultra app emphasizes efficiency with a clean UI, customizable menus, and straightforward access to advanced tools such as needle guidance. 

• It supports over 18 body markings and 15+ specialty-tailored presets, alongside annotations and 25+ measurements. This includes several automated cardiac function metrics, making it robust for cardiovascular assessments. 
• Its imaging modes cover B-mode, M-mode, Color Doppler, Power Doppler, and Pulsed Wave Doppler. 
• Additional features like harmonic imaging enhance contrast resolution by reducing artifacts. 
• It can also store cine loops up to 90 seconds, and boot-up is impressively fast at just 20 seconds.

The Butterfly iQ3, however, takes digital integration to another level. Its suite of presets spans abdomen, OB/GYN (including trimester-specific), and specialized lung applications.

It also features several advanced proprietary tools:

• Biplane Imaging™ – dual-plane visualization
• iQ Slice™ – enhanced cross-sectional imaging
• iQ Fan™ – optimized lung scanning
• ScanLab – teaching, documentation, and review platform

(However, some of these tools are iOS-exclusive.)

While the iQ3 includes extensive automated measurements, its cardiac suite is not as comprehensive as the D3Ultra’s.
