Device Story
Portable tablet-based ultrasound system (uSmart3200T/BenQ UP200) for real-time diagnostic imaging and fluid flow analysis. System comprises a tablet computer and a proprietary ultrasound engine (housed in a base compartment) that controls transducer acoustic output and processes return echoes. Data transfers via FireWire (IEEE 1394) to the tablet for image generation and display. Operated by physicians in clinical settings. Features include B-mode, M-mode, Color/Power Doppler, and spectral Doppler. Enhanced Needle Visualization (ENV) available on 15L4 transducer. System supports various transducers for diverse clinical exams. Output displayed on 11.5" touch screen; aids clinicians in diagnostic evaluation and needle/catheter guidance. Benefits include portability and high-resolution imaging for point-of-care or clinical use.
Clinical Evidence
Bench testing only. Performance evaluated via acoustic tank testing for new transducers (15L4, 16HL7, 8EC4A) per IEC 60601-2-37. Biocompatibility testing performed per ISO 10993-5 and -10. Electrical safety and EMC compliance verified per IEC 60601-1, IEC 60601-1-2, and IEC 60601-1-6.
Technological Characteristics
Portable tablet (4.9 lbs) with 11.5" touch screen and integrated Li-Polymer battery. Uses custom ultrasound engine for 128-channel transmit/receive. Connectivity via FireWire. Transducers use piezoelectric elements. Patient contact materials include ABS, Silicone, and PEI. Software runs on Windows. Sterilization/reprocessing per AAMI TIR No. 12.
Indications for Use
Indicated for diagnostic ultrasound imaging or fluid flow analysis in fetal, abdominal, intra-operative, pediatric, small organ, neonatal/adult cephalic, trans-rectal, trans-vaginal, musculo-skeletal, cardiac, and peripheral vascular applications. Used by qualified physicians.
Regulatory Classification
Identification
An ultrasonic pulsed doppler imaging system is a device that combines the features of continuous wave doppler-effect technology with pulsed-echo effect technology and is intended to determine stationary body tissue characteristics, such as depth or location of tissue interfaces or dynamic tissue characteristics such as velocity of blood or tissue motion. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

#### 4. Intended Use
The Teratech Corporation Terason™ uSmart3200T (also known as the BenQ UP200) is a general purpose Ultrasound System intended for use by a qualified physician for evaluation by ultrasound imaging or fluid flow analysis of the human body. Specific clinical applications and exam types include: Fetal, Abdominal, Intra-Operative (abdominal, organs and vascular), Pediatrics, Small Organ (Thyroid, Breast, Testes); Neonatal and Adult Cephalic; Trans-rectal, Trans-vaginal, Musculo-skeletal (Conventional and Superficial); Cardiac (Adult & Pediatric); Peripheral Vascular.
### 5. Device Description
{1}------------------------------------------------
The Terason uSmart3200T ultrasound system is a portable tablet style full feature, general purpose, and 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 version of the uSmart3200T Ultrasound Systems. The modification includes the addition of 3 transducers (15L4, 16HL7, and 8EC4A) with the no change to tablet style computer form factor.
The Terason™ uSmart3200T ultrasound system was the previously cleared on the date of May 28, 2013 as described in the 510(k) submission (K131209). This system contains a proprietary ultrasound engine for controlling the acoustic output of the transducer and processing the return echoes in real time. This data are then transferred to the tablet computer over a FireWire (aka IEEE 1394) connection for further processing and generation and 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 medicalgrade 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.
### 6. Technology Characteristics
The design and construction of the Terason uSmart3200T is same to the Terason uSmart3200T Ultrasound system which was cleared in May 2013. These systems utilize a portable computer running Windows to run the ultrasound application and a custom designed engine for control of the acoustic array and processing of the return echoes. The engine is housed in a compartment that is attached to the bottom of the tablet computer.
The uSmart3200T system contains the same ultrasound engine as the predicate device Terason T3200 ultrasound system 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 FireWire connection for further processing and generation and display of the ultrasound image

| Indications for<br>Use | The transducer is intended<br>to be used with a<br>conventional ultrasound<br>system (Terason<br>uSmart3200T) to image<br>Fetal, Abdominal,<br>Pediatric, Small Organ,<br>Cephalic, Musculo-skel,<br>Cardiac and Peripheral<br>vessel. | The transducer is intended<br>to be used with a<br>conventional ultrasound<br>system (Terason<br>uSmart3200T) to image<br>Fetal, Abdominal,<br>Pediatric, Small Organ,<br>Cephalic, Musculo-skel,<br>Cardiac, and Peripheral<br>vessel. | Same. The proposed<br>transducer and the<br>predicate transducer have<br>the identical claim of<br>imaging similar regions in<br>the human body. |
| Acoustic Array<br>Technology: | Piezoelectric elements | Piezoelectric elements | Same. |
| Acoustic Array<br>Style: | Linear Array | Linear Array | Regarding Safety: Both<br>arrays allow focused<br>transmission and<br>reception of ultrasound<br>energy to enhance image<br>quality within the region of<br>interest. |

| Acoustic Array | The transducer imaging<br>performance has been<br>evaluated in an acoustic<br>tank. | The transducer<br>performance has been<br>evaluated in the previous<br>510(k) filing (K131209). | Same. As the predicate<br>device and therefore has<br>same acoustic<br>characteristics. To ensure<br>proper safety guidelines<br>are met, acoustic testing |
| | | | was performed per the<br>IEC60601-2-37 standard. |
| Patient Contact<br>Material | Silicone ABS | Silicone ABS | Same. The 12L5A<br>transducer consists of<br>same patient contact<br>materials as the predicate<br>device. |
