Intended Use

The Teratech Corporation Terason™ uSmart3200T is a prescription-only, general-purpose Ultrasound System intended for use by a qualified physician or accredited sonographer for evaluation by ultrasound imaging or fluid flow analysis of the human body. The device is intended for use in a clinic, hospital or medical-emergency setting, Specific clinical applications and exam types include: Ophthalmic, Fetal, Abdominal, Intra-operative (Spec. and Neuro.), Pediatrics, Small Organ (Thyroid, Breast, Testes); Neonatal and Adult Cephalic, Trans-rectal, Trans-vaginal, Trans-esophageal (noncardiac), Musculo-skeletal (Conventional and Superficial), Cardiac (Adult & Pediatric), Trans-esophageal (cardiac), and Peripheral Vascular.

Device Description

The Terason uSmart3200T ultrasound system is a portable tablet-style, fullfeature, general purpose diagnostic ultrasound system used to acquire and display high-resolution, real-time ultrasound data through multiple imaging modes. The Terason uSmart3200T Ultrasound System is equivalent to the previously cleared versions of the uSmart3200T Ultrasound Systems. The modification includes the addition of 6 transducers (5V1A. 15L4A. 16L5, 15WL4. XY-Biplane, 10EC4), the Ophthalmic IFU associated with the 15L4A transducer with no change to the tablet-style computer form factor.

The Terason™ uSmart3200T ultrasound system was the previously cleared on the date May 9, 2015 as described in the 510(k) submission (K150533). This system contains a proprietary ultrasound engine for controlling the acoustic output of the transducer and processing the return echoes in real time. These data are then transferred to the tablet computer over a Universal Serial Bus (USB3) connection for further processing and generation/display of the ultrasound image.

The Terason™ uSmart3200T ultrasound tablet weighs 4.9 pounds (2.21 Kg) and has an 11.5" backlit touch screen. The tablet dimensions (8.82"(H) x 12.64"(W) x 1.25"(D)) are chosen to allow portability. A Lithium-Polymer battery (integrated into the tablet) provides 2 hours of continuous ultrasound scanning. The tablet includes a docking station (for charging) that uses a medical-grade power supply. The ultrasound transducer connector is identical to that used in the Terason™ predicate device, the uSmart3200T. Optional accessories include a cart and printer.

AI/ML Overview

The provided text is a 510(k) summary for the Terason uSmart3200T Ultrasound System. It describes the device, its intended use, and a comparison to a predicate device, focusing on safety and effectiveness. However, it does not contain information about acceptance criteria or a study proving the device meets specific performance criteria in terms of diagnostic accuracy or clinical outcomes.

Instead, the document focuses on demonstrating substantial equivalence to a previously cleared predicate device concerning:

  • Intended Use and Indications for Use: The intended uses are the same.
  • Technological Characteristics: The core technology (ultrasound engine, portable form factor) is the same. The differences are the addition of new transducers and an updated data connection (USB3 vs. FireWire).
  • Safety and Performance Benchmarking: Compliance with recognized electrical safety, EMC, acoustic output, and biocompatibility standards is demonstrated.

Therefore, I cannot provide the requested information about acceptance criteria for diagnostic accuracy or a study proving the device meets such criteria, as that information is not present in the given text.

However, I can extract the information related to the conformity of the device to regulatory standards and basic performance checks which serve as the "acceptance criteria" and "study" in the context of this 510(k) submission.
