Growth and Importance of HHUS

The rapid growth of HHUS is transforming medical diagnostics, making high-quality imaging accessible in emergency rooms, outpatient diagnostics, and even remote locations. The ability to provide real-time imaging at the bedside is crucial for quick decision-making and improves patient outcomes, particularly in emergency situations. HHUS devices are now a vital tool in clinical environments where time and portability matter most.

Study Background and Device Selection

HHUS devices are defined as ultra-compact portable ultrasound systems that consist solely of a transducer and can be operated with one hand. The ultrasound images produced by these devices are transmitted to a separate display, either through a wired or wireless connection. All these devices are CE-certified, meeting European safety and compliance standards for medical products.

When evaluating various handheld ultrasound (HHUS) devices, several factors come into play beyond just the equipment itself—such as weight, transducer design, battery life, startup time, and heat generation. However, achieving excellent B-mode image quality remains a top priority.

In this comprehensive clinical comparison, nine HHUS devices were evaluated, including CHISON's SonoEye. The criteria for inclusion were stringent: devices needed to be ultra-compact, operate independently with minimal peripheral support, and provide excellent B-scan quality. This study, conducted at a leading German university hospital, aimed to explore B-scan quality, device handling, and software usability. With 12 experienced examiners, including ultrasound specialists performing over 20 weekly exams, the study offered a highly credible evaluation.

Figure 1 in the paper: Evaluation results of handheld ultrasound devices (HHUS) across key categories, including B-mode image quality (a), device handling (b), software usability (c), and overall performance (d). The order of HHUS devices is determined based on their respective scores, with black dots representing the average values.

Detailed Testing Criteria

The devices were evaluated across several key parameters:

- B-Mode Image Quality:

This included resolution and contrast, both critical for clear and accurate imaging.

- Handling:

Factors like device haptics, weight, shape, and connectivity were assessed to ensure ergonomic efficiency.

- Software Usability:

This focused on presets, depth adjustment, gain control, duplex/PRF, saving options, and overall intuitiveness. Effective software is crucial for streamlining workflows in busy clinical environments.

SonoEye: A Top Performer

In the comprehensive evaluation, CHISON SonoEye and another brand scored the highest, with experts widely acknowledging these two devices achieved an optimal balance across image quality, handling, and software functionality.

Figure 2 in the paper:

·  In the evaluation of B-mode image quality, SonoEye (3.9, 95% CI 3.6 to 4.2) ranked among the best alongside two other handheld devices. 

·  For software usability, SonoEye achieved the highest score (4.4, 95% CI 4.3 to 4.5), significantly outperforming the other devices.

·  In overall performance, SonoEye (4.1, 95% CI 3.9 to 4.2) ranked second.

Competitive Image Quality

SonoEye stood out in B-mode image quality, ranking among the top performers. This is a key factor in its success in clinical applications, as high resolution and optimal contrast are vital for accurate diagnoses. As the study mentioned, a convex transducer delivers superior B-mode images for abdominal ultrasound compared to “all-in-one” transducers designed for multiple clinical applications. SonoEye also boasts competitive image quality in Color Doppler Mode, PW Mode and CPA/DPD Mode, ensuring physicians get precise and clear visuals every time.

User-friendly Software

As we can see in the study, CHISON's SonoEye ranked highly in multiple categories, particularly excelling in software usability, where it secured the top spot. SonoEye APP offers an intuitive, user-friendly experience, allowing clinicians to adjust settings like depth and gain with ease.  Once it connects your phone or pad to start scanning, you can do all operations with one thumb just like what you do in a traditional system. Effective software is crucial for streamlining workflows in busy clinical environments. Simple operation saves time and lets doctors focus where it matters most—on patients. 

Ultra-Portability

Moreover, SonoEye’s lightweight-design makes it an ideal choice for clinicians who need to carry the device between departments or use it in various settings. Light as a smartphone, it fits right in your pocket, making it incredibly portable and convenient. Specialized for clinicians, this pocket-sized ultrasound SonoEye packs a punch with its compact design, versatile modes supported, and rugged waterproof build.

With its advanced software and portable form factor, SonoEye is perfect for bedside diagnostics, emergency rooms, and outpatient settings.

Future Potential of HHUS

The exact boundaries between the applications of HHUS and conventional high-end ultrasound are still evolving. However, HHUS devices offer far more than simple fluid detection. In the future, we can expect an increasing use of HHUS in orthopedic and respiratory clinical settings, further expanding its potential in diverse medical fields.

The study suggests that as HHUS technology improves, these devices will find even broader applications, extending beyond traditional medical settings. There's potential for use in ultrasound training, where easy-to-use, portable devices like SonoEye can help educate the next generation of healthcare professionals. With advances in AI and cloud-based data storage, HHUS devices may also be incorporated into non-medical fields, expanding diagnostic capabilities to areas previously inaccessible.

Conclusion

CHISON's SonoEye has proven itself as a leader in the HHUS market, offering unparalleled usability, high-quality imaging, and a design that caters to the fast-paced demands of modern healthcare. For clinicians seeking a reliable, intuitive, and efficient handheld ultrasound device, SonoEye stands out as a top choice, providing cutting-edge technology and enhanced patient care.
