Indications for Use

The device is indicated for use as an adjunct to mammography for B-mode ultrasonic imaging of a patient's breast when used with an automatic scanning linear array transducer.

Device Story

Automated Breast Ultrasound System (ABUS) provides automated ultrasound imaging of breast tissue; intended as adjunct to mammography for radiologists. System utilizes automatic scanning linear array transducers to capture B-mode ultrasound images. Hardware and software modifications enable Harmonic Imaging, Spatial Compounding, and Speckle Reduction features. Radiologists review ultrasound images alongside mammograms to assist in clinical assessment. Device operates in clinical settings; intended for prescription use.

Clinical Evidence

Bench testing only. Performance verified according to U-Systems process for Design Control compliant with 21 CFR Part 820.30.

Technological Characteristics

Diagnostic ultrasound imaging system; B-mode operation; automatic scanning linear array transducers (L9-5XW, L10-5XW, L12-6XW). Features include Harmonic Imaging, Spatial Compounding, and Speckle Reduction. Class II device; 21 CFR 892.1560 and 892.1570.

Indications for Use

Indicated for B-mode ultrasonic imaging of the breast as an adjunct to mammography in patients requiring breast examination.

Regulatory Classification

Identification

An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

Special Controls

*Classification.* Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

Predicate Devices

• FFBU device (K032640)
• Siemens Antares DUS (K023720)
• ContextVision Sharp Image View (K024028)

### A. Legally Marketed Predicate Device

The ABUS System modification is substantially equivalent to the sponsor's original FFBU device (K032640) as well as Siemens Antares DUS (K023720) and the ContextVision Sharp Image View (K024028). The intended use and the technological characteristics of the modification are the same as the predicate devices.

### B. Device Description

The ABUS system, with automated ultrasound im-aging of the breast, gives the radiologist a cost effective solution for reviewing the ultrasound images with the corresponding mammogram.

The FFBU Diagnostic Ultrasound System modification represents limited hardware and software changes to the Sponsor's predicate device.

### C. Intended Use

The device is indicated for use as an adjunct to mammography for B-mode ultrasonic imaging of a patient's breast when used with an automatic scanning linear array transducer.

### D. Substantial Equivalence

The ABUS System modification is substantially equivalent to the original FFBU device (K032640) as well as Siemens Antares DUS (K023720) and the ContextVision Sharp Image View (K024028).

### E. PERFORMANCE DATA

The ABUS System performance has been verified according to the U-Systems process for Design Control which is compliant with 21 CFR Part 820.30.
