Ultrasound System Performance

Ultrasound machines, with their various components and types, have revolutionized the field of medical imaging. These devices enable healthcare professionals to visualize internal structures, assess conditions, and guide interventions with real-time imaging capabilities. Today, medical ultrasound systems are complex signal processing machines. Assessing the performance of an ultrasound system requires understanding the relationships between the characteristics of the system, such as the point spread function, temporal resolution, and the quality of images. Image quality aspects include the detail resolution, contrast resolution and penetration. Systems with microbubble scanner modification are particularly suitable for contrast enhanced ultrasound.

•

Low-performance systems constitute approximately 20% of the world ultrasound market. These ultrasound machines are characterized by basic black and white imaging and are primarily used for basic OB/GYN applications and fetal development monitoring. They are often purchased by private office practitioners and small hospitals, with a unit cost below $50,000. These scanners commonly come equipped with a transvaginal probe.

•

Mid-performance sonography systems also hold around 20% market share. These machines are basic gray scale imaging, color and spectral Doppler and are used for routine examinations and reporting. They typically utilize a minimum number of scanheads and find applications in radiology, cardiology, and OB/GYN. The cost of these systems ranges between $50,000 and $100,000. Refurbished advanced and high-performance ultrasound machines with fewer optional features can also be found in this price range.

•

High-performance ultrasound systems generally provide high-resolution gray scale imaging, advanced color power and spectral Doppler capabilities. They usually include advanced measurement and analysis software, image review capabilities, and a variety of probes. These high-performance sonography devices have a market share of approximately 40% and cost between $100,000 and $150,000.

•

The remaining 20% of the market consists of premium or advanced performance ultrasound systems, typically sold for over $150,000. Premium performance systems offer high-resolution gray scale imaging, advanced color flow, power Doppler, and spectral Doppler, as well as features like tissue harmonic imaging, image acquisition storage, display and review capabilities, advanced automation, and more. Premium systems are equipped with a wide assortment of transducer scanheads.

In summary, ultrasound machines have diverse performance levels and corresponding price ranges, catering to various medical imaging needs. From low-performance systems with basic imaging capabilities to high-performance and premium systems with advanced features, ultrasound technology continues to advance healthcare imaging capabilities.
