Indications for Use
The Sofia™ (ATUS) device is indicated for use as a B-mode ultrasonic imaging system for imaging of a patient's breast when used with an automatic scanning linear array transducer. The device is not intended to be used as a replacement for screening mammography.
Device Story
Sofia™ (ATUS) is an automated breast ultrasound system; consists of exam table with pyramid-shaped dome, motor drive, fluidics system, and ultrasound probe. Patient lies prone with breast in pendulous position within fluid-filled dome; eliminates need for breast compression. Device uses automated linear array transducer to acquire serial 2D B-mode grayscale ultrasound images of entire breast. System integrates with commercially available ultrasound system (GE LOGIQ e) to acquire and store data. Radiologist reviews 2D images to identify abnormal anatomical features. Facilitates diagnostic breast imaging; provides alternative to manual compression-based ultrasound systems.
Clinical Evidence
Bench testing only. Included mechanical performance evaluations, simulated use tests, and acoustic output testing. Conformance to IEC 60601 series electrical and electromagnetic safety standards verified.
Technological Characteristics
Automated B-mode ultrasonic imaging system. Uses linear array transducer (GE 12L-RS, 7-11 MHz). Components: exam table, motor drive, fluidics system. Connectivity: integrates with GE LOGIQ e ultrasound system. Standards: IEC 60601-1, UL 60601-1, CAN/CSA-C22.2 No. 601.1-M90, IEC 60601-1-2.
Indications for Use
Indicated for B-mode ultrasonic imaging of the breast in patients requiring diagnostic ultrasound examination. Not intended as a replacement for screening mammography.
Regulatory Classification
Identification
A diagnostic ultrasonic transducer is a device made of a piezoelectric material that converts electrical signals into acoustic signals and acoustic signals into electrical signals and intended for use in diagnostic ultrasonic medical devices. Accessories of this generic type of device may include transmission media for acoustically coupling the transducer to the body surface, such as acoustic gel, paste, or a flexible fluid container.

# 2. General Information
| Name: | iVu Imaging Corporation |
|----------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Trade Name: | Sofia™ (ATUS) Imaging Device |
| Classification Name: | Transducer, Ultrasonic, Diagnostic |
| Classification: | This device is classified by the Reproductive, Abdominal<br>and Radiological Devices into Class II, (21 CFR 892.1560<br>Ultrasonic pulsed echo imaging system and 892.1570<br>Diagnostic ultrasonic transducer) |
## 3. Device Description
The Sofia™ (ATUS) device consists of three (3) major components 1) an exam table which houses the examination pyramid, motor drive assembly, fluidics evacuation and storage system, and the power supply assembly 2) an ultrasound probe which is embedded into the exam pyramid on one end and connected to the ultrasound system on the other end, 3) an ultrasound system that acquires and stores the ultrasound data from the patient's breast exam.
{1}------------------------------------------------
The Sofia™ (ATUS) device, as well as, the two predicate devices (Trade Name: FFBU Diagnostic Ultrasound System manufactured by U-Systems, Inc (K032640), Trade Name: ABUS Diagnostic Ultrasound System manufactured by U-Systems, Inc (K052355) utilize standard B-Mode grayscale ultrasound to achieve their intended use. Both the Sofia™ (ATUS) device and the U-Systems FFBU and ABUS systems use automated linear ultrasound transducers to evaluate breast tissue. The Sofia™ (ATUS) device, as well as, the U-Systems FFBU and ABUS systems all use automated linear transducers to acquire serial 2D grayscale images of the entire breast. These 2D images can then be reviewed by a radiologist to determine if any abnormal anatomical features are present in the patient's breast. The Sofia™ (ATUS) system utilizes the same mode of operations, general operating principals, as well as, general and specific indications for use as the predicate devices described above.
## 4. Intended Use
The Sofia™ (ATUS) device is indicated for use as a B-mode ultrasonic imaging system for imaging of a patient's breast when used with an automatic scanning linear array transducer. The device is not intended to be used as a replacement for screening mammography.
#### 5. Substantial Equivalence Comparison
The iVu Sofia™ (ATUS) device is substantially equivalent to the following devices with respect to intended use, design, materials and construction:
- The FFBU Diagnostic Ultrasound System manufactured by U-. Systems, Inc (K032640)
- . The ABUS Diagnostic Ultrasound System manufactured by U-Systems, Inc (K052355).
Section 4 of this 510K shows much more detail relative to specific similarities and differences between the Sofia™ (ATUS) system and the predicate devices; also a table is provided for clarity. The Sofia™ (ATUS) device and the predicate devices are substantially equivalent in their intended uses and / or device design. In addition to the similar intended use, all of the predicate devices utilize B-Mode Grayscale Ultrasound to achieve their intended use. Both the Sofia™ (ATUS) and the predicate devices use automated linear ultrasound transducers to image breast tissue. Both the Sofia™ (ATUS) device and the predicate devices use commercially available FDA 510K approved ultrasound systems to acquire ultrasound images.
{2}------------------------------------------------
The Sofia™ (ATUS) system uses the GE LOGIQ e (K050126). The U-Systems ABUS and FFBU systems use the Siemens Antares DUS (K023720). Refer to Attachment I for a copy of the GE Medical Systems 510K (K050126).
A brief discussion of the similarities and differences between the Sofia™ (ATUS) device and its predicate devices is provided below.
#### Similarities
- Similar to the Sofia™ (ATUS), the U-Systems FFBU system uses an automated . linear transducer to acquire serial 2D images of the patient's breast. The FFBU system uses a commercially available FDA 510K approved ultrasound system to acquire and process B-Mode grayscale images of a patient's breast.
- Similar to the Sofia™ (ATUS), the U-Systems ABUS system uses an automated . linear transducer to acquire serial 2D images of the entire patient's breast. The ABUS system uses a commercially available FDA 510K approved ultrasound system to acquire and process B-Mode grayscale images of a patient's breast.
#### Differences
- . The Sofia™ (ATUS) system uses an FDA 510K approved linear transducer manufactured by GE Medical Systems. The U-Systems ABUS device uses a custom automated linear transducer. The transducers listed above are all broad band transducers with frequency ranges between 7MHZ and 11MHZ.
- t The Sofia™ (ATUS) system positions the patient in a prone position lying on its examination table with the breast in a pendulous position within the pyramid shaped dome. The U-Systems ABUS and FFBU devices position the patient in a supine position and use the transducer housing of its devise to compress the breast tissue between the transducer face and the thoracic wall.
- . iVu's pendulous position of the breast in a fluid environment eliminates the need for breast compression. No new issues of safety or efficacy are created.
### 6. Summary of Studies
The function and performance of the Sofia™ (ATUS) system have been evaluated through non-clinical design verification and validation tests. Testing included mechanical performance evaluations and simulated use tests. The results of the Sofia™ (ATUS) systems performance evaluations demonstrate that the Sofia™ (ATUS) device design is well suited for its intended use.
iVu Imaging completed mechanical performance evaluations to verify that the Sofia™ (ATUS) system meets predetermined specifications, conforms to product performance requirements, and supports the compatibility of internal components. Test results, as documented in Section 7, support that the Sofia™ (ATUS) system meets the predetermined specifications and performance requirements for its intended use.
{3}------------------------------------------------
Additional testing of The Sofia™ (ATUS) device will be performed by an independent testing laboratory (Intertek Testing Services NA, Inc) and must demonstrate conformance with the IEC 60601 series of electrical and electromagnetic safety standards before commercial distribution begins. In Section 7 of this document, under "ELECTRICAL SAFETY TESTING" is a signed certification by the President of iVu attesting to the fact that such testing will occur prior to commercialization. The following specific standards will be tested.
