Features to Expect With a Point of Care Ultrasound Machine
These are some of the most compact, portable ultrasound machines available, and clinicians often use them for cardiac, OB/GYN, vascular, internal medicine, urology, musculoskeletal, pain management, veterinary, and many other applications.
These devices have many of the same features as larger models, and they work well for professionals who have little storage space and treat patients in multiple locations. POCUS ultrasounds are available with stands or carts, and many models have color Doppler imaging for monitoring blood flow in various tissue types.
Automatic Image Optimization (AIO) reduces operator fatigue and increases scan accuracy and consistency. With needle visualization, you can administer local anesthesia or other medications and drain excess fluid when needed.
The GE Vscan With Dual Probe
The GE Vscan With Dual Probe is the best pocket-sized point-of-care ultrasound machine, and it looks a lot like a flip phone. The Vscan line was the first series of handheld ultrasounds, with this model costing between $5,500 and $8,250. The Vscan With Dual Probe comes with two transducers mounted at opposite ends of the probe. A linear transducer gives clear images of structures near the surface of the body, and a convex transducer allows for transcranial and cardiac imaging.
The linear scanner’s maximum depth is 8 centimeters, and the convex scanner has up to a 75-degree field of view with up to 24 centimeters of scanning depth. You can change between convex and linear scanning easily and boot the Vscan up to start scanning in less than 25 seconds. After you complete a scan, you can view and interpret the data on a PC. Other features include:
- A 3.5-inch LCD display with 1024 x 768 resolution
- A one-hour battery life
- A 75-minute battery charging time for 90% capacity
- A compact changing station
- A sleep mode to conserve battery power
- A soft case
- A 4GB microSD card
- Presets for many applications
- Voice annotations
- ColorFlow directional imaging
- Well-placed buttons
- A thumb-controllable navigation wheel
- AutoOptimize automatic gain adjustment
- AutoCycle to detect the full heart cycle
- Power angio
- Pulse wave or PW Doppler
The Siemens Acuson Freestyle
The Siemens Freestyle is the best point-of-care ultrasound machine with wireless sensors. It’s the world’s first wireless ultrasound, and it usually costs between $8,500 and $10,000. It resembles a tablet, and you can use it to conduct scans with wireless probes up to 10 feet away. The machine is available with one convex and two linear transducers, and integrated controls on the transducers let you operate the system from a distance. The Siemens Freestyle has a touch screen, knobs, buttons, and an intuitive menu with a customizable workflow that makes viewing ultrasounds and entering patient data easy.
The control panel and transducers are fully submersible for easy cleaning and sterilization. Time gain control automation normalizes signal amplitude with time, compensating for depth. This function makes scans easier to interpret by giving similar tissues at different depths the same levels of brightness. You can set the focus and frequency to adjust automatically as well. Spatial compounding combines several images from slightly different angles for a better view with more definition and fewer speckles. Three image size options are available. This point-of-care ultrasound also comes with:
- A 15-inch LED monitor with 1024 x 768 resolution
- Two USB ports
- A 1.5-hour battery life
- Enhanced needle visualization
- Color Doppler imaging
The SonoSite Edge II
The SonoSite Edge II by FujiFilm is the best laptop-style point-of-care ultrasound machine. It usually costs between $14,000 and $16,000 and has easy-to-use remappable knobs, buttons, and a trackpad. The durable design works well in a variety of environments. The rugged case has a carrying handle, and the low-profile, silicone keypad is liquid-resistant for easy cleaning and sterilization. The transducers have armored cables to prevent damage if they get run over by the optional Edge Stand or other equipment. It’s available with a variety of probes, and the scanning depth is up to 35 centimeters.
You can start this machine and be ready to scan in less than 25 seconds. It’s easy to adjust the gain and the dynamic range, which is the difference between the minimum and maximum signal values, for better contrast. With many of the available transducers, DirectClear technology increases penetration and contrast resolution. You can add connections for three transducers and a PowerPark wireless charging station. With the SonoSite Edge II, standard features include:
- A 12.1-inch LCD monitor with 1024 x 768 resolution and an antireflective coating
- A two-hour battery life
- Dual imaging that shows regular or B-mode and color Doppler scans next to each other
- Duplex imaging combines the two scans into one image
