What to Consider When Buying an Ultrasound Machine

To get the most value out of your ultrasound purchase, take time to consider the following:

  • The intended clinical use of your device
  • Does your practice need a portable or stationary ultrasound machine?
  • Should you buy a new or refurbished ultrasound machine?

Intended Clinical Use

The intended clinical use of your ultrasound machine will likely be the determining factor in your purchasing decision. Most healthcare teams benefit from buying a shared service ultrasound machine that they can use across multiple medical specialties.

Another consideration is whether you will use your ultrasound for diagnostic purposes, treatment, or both – this will determine the key features to seek out in your prospective ultrasound system.

For instance, surgical teams and anesthesiologists often use ultrasounds for perioperative purposes. They will benefit from purchasing a device with advanced features like HD Live viewing and Needle Recognition for precise needle or catheter placements.

Do You Need a Portable Ultrasound Machine?

The size of your medical office can help you determine if you need a portable ultrasound machine or a stationary console. You will likely benefit from purchasing a portable ultrasound machine if you practice in a multi-specialty medical office where equipment is frequently moved between units.

New vs. Refurbished Ultrasound Machines

Should you purchase a new or refurbished ultrasound machine? On the one hand, new ultrasound systems often come with longer warranty coverage. On the other hand, refurbished ultrasound machines can provide equal performance to new machines at a fraction of the cost.

If cost is a determining factor for you, consider purchasing a refurbished ultrasound machine from a seller with high-quality after-sales support.

Strata Imaging has a proven track record of excellent after-sale technical support, offering full maintenance and repair services on every purchase. We take customer service seriously and strive for a 24-hour or less response time to all customer repair requests.
