Diagnostic ultrasound machines come in many forms.
This guide offers an in-depth look at what to consider when purchasing an ultrasound machine, helping you navigate the diverse range of available options.
These machines use high-frequency sound waves to create live images, making them a popular choice for imaging due to their non-ionizing nature, unlike X-rays.
Ultrasound machines serve various purposes, resulting in numerous specialized types. Choosing the right one involves careful consideration.
So, how do you pick the right one?
This guide will walk you through the main points of that decision.

Ultrasound Machine Applications
Different ultrasound machines cater to specific types of examinations. For instance, an advanced cardiac system might not be optimal for OB/GYN.
When evaluating ultrasound machines for sale, consider what examinations the system will be used for. The most common applications include:
- Cardiac/Cardiovascular Ultrasound Machines
- OB/GYN Ultrasound Machines
- General Imaging Ultrasound Machines
- Shared Service Ultrasound Machines

Cardiac
Cardiac and cardiovascular ultrasound machines are specialized for heart and vessel examinations. An echocardiogram measures the heart's size, shape, and motion. These ultrasounds often include advanced options for better imaging and data analysis.
Typically, you'll need a phased array probe and possibly a TEE probe for certain cardiac exams. Pencil probes are useful for examining blood movement.
-
OB/GYN
OB/GYN stands for obstetrics and gynecology. Obstetric ultrasounds confirm pregnancy, determine gestational age, locate the placenta, and identify fetal issues. Gynecological ultrasounds image female reproductive organs, assessing size, position, and potential abnormalities. For OB/GYN, convex and endocavity probes are generally needed.
-
General Imaging
General imaging ultrasound systems cover a wide range of applications including abdominal, musculoskeletal, small parts, urological, and vascular examinations. They can often be upgraded for cardiology exams, making them versatile choices. Probe selection should be guided by intended exam types.
Main Ultrasound Brands and Series
Four main brands dominate the ultrasound market: Siemens, GE, Philips, and Canon (formerly Toshiba). Other popular brands include Samsung, Esaote, Sonosite, and Supersonic.
These brands offer high-quality equipment with good value, even when purchased used. Below is an overview of the main series within each of these brands, focusing on popular used market models.
Siemens Ultrasound Series
Siemens offers versatile ultrasound machines, categorized by performance rather than application. The Acuson X-series, including models like X300 and X700, covers entry to mid-range general imaging. Popular models include Siemens S2000 and systems like Acuson S1000, S2000, and S3000, featuring advanced imaging technologies. Dedicated cardiac systems like Acuson SC2000 are also available, along with newer series Sequoia, Redwood, and Juniper, focusing on general imaging and shared services.
Philips Ultrasound Series
Philips organizes its ultrasound series by performance, offering solutions for various applications through general imaging systems. The ClearVue Series includes entry-level models such as 350 and 550. Affiniti Series covers mid-range systems like Affiniti 30 and 70. The high-end Epiq Series features models like Epiq 5 and 7. Additionally, Philips offers the portable CX50 for general imaging.
Canon Ultrasound Series
Canon, formerly Toshiba, provides two lines for general ultrasounds. The Xario Series includes entry-level systems like Xario 200 and 100MX, while the Aplio Series features mid-line models such as Aplio 300 and 500 Platinum. Canon's newer models include the i600 and i700. They also offer a portable ultrasound, Viamo c100, for general imaging.
Samsung Ultrasound Series
Samsung offers a range of ultrasound systems for OB/GYN, general imaging, and shared service. Popular OB/GYN models include HS50, HS30, and WS80A Elite. General imaging options feature RS85 Prestige and HS60. Samsung HS70A is suitable for cardiovascular imaging, and newer models V8 and V7 are also available. For shared service, consider HS70 and HS60.
The Prices of Ultrasound Systems
How much does an ultrasound machine cost? Prices vary widely due to factors like age, condition, and model. At LBN Medical, ultrasounds range from 5,000 to 80,000 Euros. The matrix below shows an overview of ultrasound prices by brand, condition, and type. Costs are in thousand euros for the system box only. Generally, used systems are 4-7 years old, offering good value for advanced equipment. For more detailed pricing information, read our full post on “How much does an ultrasound machine cost.”

Used, Refurbished, or New Ultrasounds
Understanding the pros and cons of used, refurbished, and new ultrasounds is crucial when making your choice.
Used Ultrasounds
Used equipment varies greatly. Some sellers provide systems "as is," with no modifications. Options and configurations remain as the previous owner had them, posing more risk but often lower cost. Other sellers, like professional vendors, ensure high quality by cleaning and testing all used machines, offering excellent value for money.
Refurbished Ultrasounds
Refurbished equipment can also differ. Sellers might offer general refurbishment, ISO-certified refurbishment, or OEM refurbishment. Basic refurbishment might include cosmetic and functional updates like cleaning, painting, parts replacement, and installing options. ISO and OEM refurbishments follow strict processes for high-quality results. It's essential to ask about the specific refurbishment process.
New
New systems are brand new, ensuring zero risk but at a higher price.
Ultrasound Specifications
Considering various ultrasound specifications can help you pick the right model. Key aspects include:
Licenses
Ultrasound machines may come with general options, but specialized examinations often require additional licenses, enabling extra functionalities. Ensure you have the necessary licenses for your needs.
Ultrasound Ports
Check the number of ports, as each port accommodates different ultrasound probes. Having enough ports for various probes eases workflow during examinations.
Year of Manufacture
While the age of ultrasound equipment isn't always critical, it can matter if your country imposes import restrictions or if you need state-of-the-art features available only in newer models. Software and hardware are sometimes upgradable on older systems.
Power Compatibility
Check for power compatibility with the voltage in your country. Some ultrasounds require 110V or 220V, so ensure compatibility or get a transformer if necessary.
User Language
Ultrasound system languages can vary according to where it was purchased. Confirm that the language meets your requirements.

Condition of Used Ultrasound Machines
The condition often matters more than age. Used ultrasound machines’ condition can vary based on service history and wear. If cosmetic appearance matters, consider having the reseller paint the unit for a newer look.
Ultrasound Machine Peripherals
Consider any additional peripherals you might need, such as biopsy kits, printers, and probes.
Which Ultrasound Probes to Get
Probes, also known as transducers, are crucial for sending and receiving signals. Not all probes are compatible with all ultrasound systems, so ensure compatibility with your chosen model. Different types of probes are suited for specific examinations, varying by footprint size, frequency, and piezoelectric crystal arrangement.
Linear Probes
These probes have a large footprint and high frequency (7-18 MHz), providing good near-field resolution. They are ideal for vascular, small parts, nerve, musculoskeletal, and breast imaging.
Convex Probes
Convex probes feature a large footprint and low frequency (2.5-5 MHz), suitable for in-depth examinations such as abdominal, vascular, nerve, musculoskeletal, and OB/GYN ultrasounds. A subtype, micro convex, has a smaller footprint for neonatal and pediatrics.
Phased Array Probes
These probes have a small footprint and emit low-frequency ultrasound (2-8 MHz), offering lower resolution but deeper penetration. They are used for imaging through acoustic windows in the skull or intercostal spaces.
Specialized Probes
Specialized probes, such as internal probes for specific bodily orifices, transoesophageal (TEE) probes for heart imaging through the esophagus, and pencil (CW Doppler) probes for measuring blood movement, cater to unique imaging needs. Surgical probes like laparoscopic probes are also available.
Ultrasound Maintenance
Proper maintenance of your ultrasound system can prolong its performance. Here are five key maintenance tips:
- Daily Checks of the Ultrasound Machine
- Pay Attention to Your Ultrasound Probes
- End of Shift Prevention
- Full System Backup
- Preventive Maintenance for Your Ultrasound
