EPIQ Series Diagnostic Ultrasound System

The EPIQ Series Diagnostic Ultrasound System has been enhanced with the mL26-8 linear array transducer, expanding its capabilities to high-resolution superficial and Ophthalmic imaging. This advancement relies on established ultrasound principles and rigorous non-clinical testing to ensure its safety and effectiveness for diverse diagnostic applications.

The EPIQ Series Diagnostic Ultrasound System has been updated to incorporate the new mL26-8 transducer, a linear array probe operating at a frequency of 6-13.33 MHz. This transducer is specifically designed for high-resolution superficial imaging, targeting applications such as Musculoskeletal (Superficial), Ophthalmic, Pediatric, Peripheral Vessel, and Small Organ imaging (including Breast, Thyroid, and Testicle). A key enhancement with this update is the expansion of the system's indications for use to include Ophthalmic applications, a capability supported by data from a reference device. The system functions through diagnostic ultrasound imaging and fluid flow analysis, employing technologies like pulsed Doppler and pulsed echo imaging. The introduction of the mL26-8 transducer, with its higher frequency range (within established guidance limits), aims to improve image quality for superficial structures. The safety and effectiveness of the system, including the new transducer, were validated through comprehensive non-clinical performance testing. This testing encompassed adherence to various industry standards for medical electrical equipment, electromagnetic compatibility, usability, and specific requirements for ultrasonic diagnostic equipment, ensuring the device meets its design specifications and risk control measures without requiring new clinical trials for this particular update.
