The used GE LOGIQ S8 ultrasound machine is GE’s advanced ultrasound in its “Signature” series of compact, mid-range ultrasounds. The S8 is available as a shared service ultrasound, offering stress echo for cardiac scanning as well. The LOGIQ S8 fills a void for those who have high volume and are looking for very good ultrasound, but don’t have the budget to afford the cost of a refurbished ultrasound from GE’s Expert series of systems.
