Indications for Use

QLAB Quantification Software is a software application package. It is designed to view and quantify image data acquired on Philips Healthcare ultrasound products.

Device Story

QLAB Quantification Software with Heart Model is a software application for ultrasound image review and quantification. It functions as a standalone PC application, on a dedicated workstation, or integrated into Philips ultrasound systems. The Heart Model application performs automatic 3D anatomical segmentation of heart chambers for End Diastole (ED) and End Systole (ES) phases. It identifies chambers and draws borders for standard ASE apical and short-axis views. The user reviews these borders and chooses to accept or reject the automated output. The device generates LA and LV volumes, streamlining cardiac 3D quantification. Clinicians use these measurements to support cardiac assessment. The software benefits patients by providing standardized, efficient chamber quantification, with performance validated against cardiac MRI.

Clinical Evidence

Clinical evaluation involved external validation by clinicians to assess functionality and performance. The study confirmed the device met its intended use and that the automated LA and LV chamber measurements showed correlation to cardiac MRI. No specific statistical metrics (e.g., p-values, CIs) were provided in the summary.

Technological Characteristics

Software-based image processing and quantification application. Operates on standard PCs, dedicated workstations, or on-board ultrasound systems. Utilizes an automated 3D anatomical segmentation algorithm (reused/modified from CT). Supports ASE/ESE standard view displays. Connectivity via standard ultrasound system interfaces. No specific hardware materials or sterilization requirements as it is a software-only package.

Indications for Use

Indicated for clinicians requiring review and quantification of ultrasound image data for cardiac chamber analysis, specifically for obtaining 3D quantitative measurements of the left atrium (LA) and left ventricle (LV) in adult patients.

Regulatory Classification

Identification

A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.

Special Controls

*Classification.* Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).

#### 3. 510(k) Summary ·

This summary of safety and effectiveness is provided as part of the Premarket Notification in compliance with 21CFR. Part 807 Subpart E, Section 807.92.

Philips Ultrasound, Inc. 3000 Minuteman Road Andover, MA Penny Greco, Regulatory Affairs Specialist Telephone: [phone] Facsimile: [phone] E-mail: [e-mail]

Date prepared: January 21, 2013

2) Name of the device, including the trade or proprietary name if applicable, the common or usual name, and the classification name, if known:

| Common/Usual Name: | Picture Archiving and Communications Systems Workstation |
|----------------------|----------------------------------------------------------------------------------|
| Proprietary Name: | QLAB Quantification Software with Heart Model |
| Classification Name: | CFR 892.2050, system, image processing, radiological, Product code LLZ, Class II |

## 3) Substantially Equivalent Devices

Philips Ultrasound believes that the OLAB software with the Heart Model application is substantially equivalent to other commercially available products, including Philips QLAB Cardiac 3DQ and 3DQA (K040227 & K042540), Philips Brilliance CT (K042293), and Siemens syngo US Workplace (K091286).

#### 4) Device Description

The OLAB software application is available either as a stand-alone product that can function on a standard PC, a dedicated workstation, and on-board Philips' ultrasound systems. It can be used for the on-line and off-line review and quantification of ultrasound studies.

QLAB Quantification software now includes the Heart Model application.

# Heart Model

The Heart Model application provides automatic 3D anatomical segmentation and identification of the heart chambers for the End Diastole (ED) and End Systole (ES) cardiac phases. The Heart Model segmentation algorithm draws segmented borders for select standard American Society of Echocardiology (ASE) apical and short axis views. This provides a streamlined workflow for obtaining cardiac 3D quantitative heart chamber measurements and calculated result values.

## 5) Intended Use

QLAB Quantification software is a software application package. It is designed to view and quantify image data acquired on Philips Healthcare ultrasound products.

# 6) Technological comparison to predicate devices

QLAB Heart Model algorithm is reused from Philips Brilliance CT (K042293), but modified for ultrasound. It is similar to QLAB 3DQ/3DQA and the Brilliance CT Comprehensive Cardiac Analysis (CCA) in that the user is able to evaluate the image in the ASE/ESE American Society of Echocardiography and European Society of Echocardiography standard views display. While 3DQ requires the user to place reference points to finish a trace, QLAB Heart Model finds the chambers of the Heart and then displays the Heart Model determined chamber borders in the ASE/ESE views for the user to Accept or Reject. Similar to Siemens syngo US Workplace, QLAB Heart Model automatically generates left atrial (LA) and left ventricular (LV) volumes.

#### 7) Non-clinical performance data

No performance standards for PACS systems or components have been issued under the authority of Section 514. The Heart Model application was tested in accordance with Philips verification and validation processes. Quality assurance measures were applied to the system design and development, including:

- Risk Analysis .
- Product Specifications ●
- Design Reviews .
- Software Verification & Validation ●

#### Summary of Clinical Tests:

The subject of this premarket submission, QLAB Heart Model, was clinically evaluated and accepted during external validation and determined to be as safe and effective as predicate devices.

External clinicians evaluated the functionality and performance of Heart Model. The external evaluation confirmed that Heart Model met its intended use and that the LA and LV chamber measurements correlated to cardiac MRI.

# 8) General Safety and Effectiveness Concerns

The device labeling contains operating instructions for the safe and effective use of the QLAB software with Heart Model.

#### 9) Conclusions

The QLAB Quantification Software with the Heart Model application incorporates components common to all image viewing systems for the display and quantification tasks within a clinical setting. Software development for the QLAB software follows documented processes for software design, verification and validation testing. A risk assessment was completed to identify potential design hazards that could cause an error or injury based on the use of the quantification results. Appropriate steps have been taken to control all identified risks for this type of image display and quantification product. Verification and validation activities of the QLAB Quantification software with the Heart Model application indicate that it meets its intended use and introduces no new issues of safety and effectiveness.
