CTS-285 WITH EZU-PL21 AND EZU-PC3B TRANSDUCERS
Diagnostic ultrasound imaging of the human body as follows: Fetal, Abdominal, Cardiac Adult (B mode, M mode)
Model CTS-285 is a compact-type linear/convex electronic scanning ultrasound system with a built-in digital scan converter (DSC). The unit allows adult heart, abdominal organ and fetal tomographic images to be observable on a video monitor. The main unit is portable and is separable from other equipment to be carried for its use at another place as well as being usable in combination with a full keyboard, 9-inch video monitor and a special photographic unit.
This 510(k) premarket notification describes the CTS-285 Diagnostic Ultrasound System. The primary method for proving substantial equivalence to the predicate device, Hitachi Medical Corporation EUB-310 (K862867), is through a comparison of technological characteristics. There are no direct performance studies with acceptance criteria in the document that would be typical for AI/ML devices. Therefore, I will create a table to compare the reported specifications of the new device (SIUI CTS-285) against its predicate (Hitachi EUB-310A) to infer "acceptance criteria" based on the predicate's established performance, and then note the new device's "performance" based on its characteristics.
