When purchasing an ultrasound machine, there are three key aspects to consider: functionality, ease of use, and cost.

The Right Features for Your Specialty

The need for specific ultrasound features varies by the type of practice.

General practitioners conducting abdominal scans would benefit from an all-purpose, large radius convex probe with a frequency of 2-5MHz. This choice is also appropriate for OB-GYNs performing pregnancy ultrasounds.

However, some physicians require more specialized equipment. For example, a cardiologist performing advanced heart scans would need a machine with Doppler capabilities and a phased array probe to navigate narrow intercostal spaces. These machines have high frame rates, effective for imaging rapid heartbeats.

Vets scanning small animals might prefer a micro-convex probe with a high frequency of ~8MHz for the best possible resolution.

Consequently, it is essential to think carefully about the specific features your practice needs.

Ease of Use and Portability Improve Adoption

For novice users, the ideal ultrasound machine should be intuitive. Many machines come with presets for common procedures, allowing you to conduct scans without adjusting numerous controls. A good system will enable users to modify system controls with simple, intuitive steps.

Portability is also a key consideration. If you intend to do house calls or need to easily move the machine within the clinic, a portable option is advantageous. Technological advances have made handheld ultrasounds increasingly attractive, offering outstanding imaging while being cost-effective.

Don't assume that portable machines are inferior; modern handheld devices like SonoEye have image quality comparable to high-quality point-of-care machines.

When integrating ultrasound into your practice, ensure it is easy to learn and use. Accessibility will likely enhance its utilization.

Factors Influencing Ultrasound Machine Cost

• Age – New machines are more expensive than used or refurbished ones. The price decreases with the age of the machine.
• Brand and Model – Established brands with newer models are generally more expensive due to advanced technologies and superior quality.
• Functionality and Application – Machines catering to a wider range of applications and providing higher flexibility are priced higher.
• Portability – Smaller and more portable machines, especially handheld ones, are significantly more cost-efficient than cart-based ultrasounds.
• Warranty and Maintenance – Maintenance costs can be included in the machine price, and a warranty is often provided by manufacturers for a limited period.

How to Choose an Ultrasound System or Machine

Choosing the right ultrasound machine is crucial, whether it's a replacement or a first-time purchase.

With numerous options available and factors to consider, making an informed choice is essential.

Let's delve into the considerations to help you select the best ultrasound machine.

What are the Most Important Factors to Consider When Choosing an Ultrasound Machine?

Imaging Mode

The imaging mode determines how ultrasound information is presented. Common modes include:

A-mode

Simple one-dimensional representation used to measure distances.

B-mode (Brightness)

2D representation of the scanned body part, used across various disciplines.

M-mode

Sequence of images showing movement and its amplitude.

Real-Time Spatial Compound Imaging

Acquires sonographic information from several angles, useful for musculoskeletal exams.

Color Doppler Imaging

Visualizes blood flow, direction, and vascularization, commonly used in cardiology.

Elastography

Measures tissue hardness, diagnosing diseases such as hepatic fibrosis.

3D / 4D (Real-Time 3D)

Three-dimensional imaging, often used for examining pregnant women.

Size

Ultrasound scanners come in various sizes, including portable options. Hand-held models are easily stored in pockets or bags, useful in emergencies.

Consider screen size: weigh up whether it is sufficient for your needs.

Weight

Portable ultrasound systems can be very lightweight. Larger machines are more cumbersome but often stay in one place. Choose a smaller, lighter machine for portability.

Image Quality

While portable machines have improved, console-based machines offer better resolution and advanced functionality. Portable machines display many shades of gray and some have color screens.

Brightness

Adjustable brightness is crucial, especially for outdoor use without compromising image quality.

Types and Number of Transducers

Transducers come in various types, including linear, curvilinear, phased array, and endocavitary probes. Choose based on the body parts you examine.

Software Required

Software enhancements can improve diagnostic capabilities and image quality. Ensure compatibility with existing systems and consider software support.

Battery Life

Battery life is crucial for portable machines. Look for long-lasting batteries or options for a second battery.

Purpose

Consider how you plan to use the ultrasound system. Different applications, such as obstetrics, gynecology, cardiology, and more, have specific requirements.

Price

Ultrasound machines vary widely in price. Refurbished machines are a cost-effective option.

Power Output

Look for machines with lower power settings to minimize the risk of burning tissues.

Frequency

Choose frequency based on imaging needs: higher frequency for superficial images, lower frequency for deeper penetrations.

Portability

Decide whether you need a portable or stationary machine. Portable machines are easier to move but may have limitations in image quality and features.

Brand

Choose reputable brands known for quality and customer service, such as Sinosite, Philips, Edan, Toshiba, GE, and Mindray.

Training Required

Consider the skill level of technicians using the new machine. Look for providers offering training options.

Warranty, Service Contracts, and Technical Support

Check the manufacturer's warranty duration and service contract terms. Ensure availability of technical support.

Availability of Spare Parts and Accessories

Ensure easy access to spare parts and accessories, such as monitors, power suppliers, and keyboards.

Condition

Decide between new or refurbished systems, weighing reliability against price. Reputable suppliers offer refurbished machines at discounted prices.

Other Features and Parameters

Consider image storage capacity, ease of image transfer, integration, connectivity with peripherals, and printer capabilities.

Conclusion

Having explored what to look for when buying an ultrasound machine, you're better equipped to make a wise investment. Your research will help you find the best portable or stationary ultrasound machines on the market.
