Evolution of the Ultrasound Table… not all tables are Biodex tables!

QA Programs for Uptake Probes and Well Counters


Since the 1980s Biodex has been pioneering the design of the ultrasound table. There has been a constant design evolution to bring about the very best in ergonomic design to the ultrasound marketplace.

For instance, something as subtle as the wheel of the table has seen a transformation, because a better designed wheel, makes for a better overall patient experience. All Biodex tables include 5-inch casters for smooth table mobility. In the past the ultrasound table had 2-inch casters. The smaller wheel limited the mobility of the table. Increasing the size of the casters allowed the table to move freely, even with a large patient on it. Keeping the patient in mind, this slight modification meant the patient can be moved from an exam room to a procedure room without having to take the patient on or off the table.

Better through design, Biodex has always looked at ways for tables to be more efficient. Each has a central locking system with a one-step locking mechanism to secure the table to the floor. Previously, each caster was individually locked. Even though this process securely locked the table to the floor it was not an ergonomic procedure to reach for each caster or walk around the table each time it needed to be locked down. The central locking system prevents reaching and walking, thus saving time.

It is all about options, and Biodex understands this. Easy access stirrups can be purchased as an option on the Biodex tables. The table is designed with an easy one-hand operation foot drop with access to the stirrups incorporated into the frame of the table. Once the foot section is lowered, the stirrups can be easily slid out and moved to a position that best fits the needs of the procedure. On older models, the stirrups had to be placed and removed each time the patient was moved on and off the table.

All Biodex tables are ergonomically designed for greatest sonographer safety. With an open chassis design, the sonographer is able to position themselves around the table without bumping into the frame of the table, which was a frequent problem with earlier designs. Procedures are done on all four sides of the table, a clear access to all sides is necessary for better ergonomic comfort. In the previous models the frame ran from caster to caster thus impeding the sonographer’s ability to move in close.

The greatest principle of scanning ergonomics is to get as close to the patient as possible when performing a scanning procedure. The optional side rails are designed to tuck underneath the table to allow clear access to the tabletop. In the past, the side rails would retract along the side of the table, thus adding 2-inches to the width of the top. This would cause the sonographer to be even further away from the patient. Reducing a sonographer’s reach is the most important element in ultrasound table ergonomic design.

The range of height adjustability of the Biodex tables allows for sonographers to sit or stand no matter what their height might be. It is important to have the table adjusted to the proper height so reach can be reduced and the proper arm angle is achieved to reduce muscle stress. With a height adjustment from 23 to 39 inches, a wide range of positions are possible. It also allows for patients of any height or wheelchair bound to be easily placed on the table without the use of a step stool. This was a great improvement form previous models where the table only went down to 29.5 inches.

The overall patient weight capacity of the table has been increased from 350 lbs to 500 lbs, the width has also been enlarged to accommodate larger patients. Again, a modification in design increases the use possibilities of the table from pediatrics to bariatric patients.

Biodex is always looking to incorporate innovative designs to bring about new ways to influence patient safety, comfort and product usage for the sonographer and the patient. Biodex does not overlook the necessity of reducing procedure time to make the table more cost effective for the facility as well.
