Intended Use

The iU22 Diagnostic Ultrasound System is intended for diagnostic ultrasound imaging in B (or 2-D), M-mode (including Anatomical M-mode), Pulse Wave Doppler, Continuous Wave Doppler, Color Doppler, Tissue Doppler Imaging, Harmonics (Tissue and Contrast) and Elastography modes (including ElastPQ). It is indicated for diagnostic ultrasound imaging and fluid flow analysis in the following applications: Ophthalmic Fetal Intra-operative Abdominal Laparoscopic Pediatric Small Organ Adult and Neonatal Cephalic Trans-rectal Trans-vaginal Musculoskeletal Urology Cardiac (Adult, Pediatric, Trans-esophageal) Fetal Echo Peripheral Vessel

Device Story

iU22 Diagnostic Ultrasound System modified to include ElastPQ (shear wave elastography) feature; system generates electronic voltage pulses transmitted to piezoelectric transducer array; transducer converts pulses to ultrasonic pressure waves; system processes Doppler shift frequencies from moving targets (e.g., blood) for flow display; ElastPQ mode transmits high-intensity, long-duration 'push' pulses to create shear waves in soft tissue; system estimates tissue stiffness by measuring shear wave travel speed; used in clinical, hospital, and point-of-care settings by healthcare professionals; output provides anatomical measurements and tissue stiffness data; assists clinicians in diagnosis; benefits include non-invasive assessment of tissue stiffness.

Clinical Evidence

No clinical trial required. Evidence includes bench testing (thermal implications of shear wave, precision and reproducibility of ElastPQ measurements) and a usability study conducted per FDA human factors guidance. Device safety supported by review of field information and compliance with established electrical and acoustic output standards.

Technological Characteristics

Diagnostic ultrasound system using piezoelectric transducer arrays. Complies with IEC 60601-1, IEC 60601-1-2, and IEC 60601-2-37. Acoustic output meets Track 3 limits (Ispta.3 ≤ 720 mW/cm², MI < 1.9, TI ≤ 6.0). ElastPQ mode utilizes high-intensity, long-duration Doppler-type 'push' pulses to induce shear waves. System supports B-mode, M-mode, Pulse/Continuous Wave Doppler, Color Doppler, Tissue Doppler, and Harmonic imaging.

Indications for Use

Indicated for diagnostic ultrasound imaging and fluid flow analysis in patients across a broad range of clinical applications including ophthalmic, fetal, abdominal, intra-operative, laparoscopic, pediatric, small organ, neonatal/adult cephalic, trans-rectal, trans-vaginal, musculoskeletal, urology, cardiac, and peripheral vessel assessments.

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.

| Philips iU22 | K093563 |
| SuperSonic Aixplorer | K112255 |

{1}------------------------------------------------

#### 4. Device Description and Technical Comparison to Predicate Devices

The subject of this 510(k) notification, the modifications to the iU22 ultrasound system and transducer(s), function in a manner identical to all diagnostic ultrasound systems and transducers. The system circuitry generates an electronic voltage pulse, which is transmitted to the transducer. In the transducer, a piezo electric array converts the electronic pulse into an ultrasonic pressure wave. When coupled to the body, the pressure wave transmits through body tissues. The Doppler functions of system process the Doppler shift frequencies from the echoes of moving targets such as blood to detect and graphically display the Doppler shifts of these tissues as flow.

ElastPQ is the Philips Ultrasound marketing name for a feature commonly referred to as The terms will be used interchangeably throughout the shear wave elastography. submission and supplemental information.

The ElastPQ (shear wave) feature provides the user with tissue stiffness information. The iU22 Ultrasound system was cleared for Elastography modes per 510(k) K093563. ElastPQ is an Elastography mode on the iU22 Ultrasound Scanner where a burst of Doppler-type "push" pulses with high intensity and long pulse duration is transmitted. This mode creates waves in soft tissues and estimates the tissue stiffness by determining the speed at which these shear waves travel. This shear wave technology is similar to the ShearWave™ feature recently cleared on Aixplorer® by SuperSonic Imagine, Inc, per 510(k) K112255.

The iU22 system gives the operator the ability to measure anatomical structures and offers analysis packages that provide information used by competent healthcare professionals to make a diagnosis.

#### 5. Intended Use

The iU22 Diagnostic Ultrasound System is intended for diagnostic ultrasound imaging in B (or 2-D), M-mode (including Anatomical M-mode), Pulse Wave Doppler, Continuous Wave Doppler, Color Doppler, Tissue Doppler Imaging, Harmonics (Tissue and Contrast) and Elastography modes (including ElastPQ). It is indicated for diagnostic ultrasound imaging and fluid flow analysis in the following applications:

> Ophthalmic Fetal Intra-operative Abdominal Laparoscopic Pediatric

{2}------------------------------------------------

## Small Organ Adult and Neonatal Cephalic Trans-rectal Trans-vaginal Musculoskeletal Urology Cardiac (Adult, Pediatric, Trans-esophageal) Fetal Echo Peripheral Vessel

The clinical environments where the iU22 4.3 system can be used include point-of-care areas in offices, clinical and hospital settings for diagnosis of patients.

#### 6. Indications for Use

The 510(k) Indications for Use forms on the following 2 pages show previously cleared indications for use for the iU22 system and the new mode of operation (ElastPQ) added with this 4.3 release of iU22. The iU22 4.3 release adds a new mode of operation (ElastPQ) for the C5-1 transducer so the Indications for Use form for C5-1is also included in this submission. All other previously cleared transducers used for the iU22 remain unchanged.
