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 processes ultrasound image data; functions as standalone PC application, workstation-based, or on-board ultrasound system. Modified plug-ins (a2DQ, aCMQ, MVN, Heart Model) provide semi-automated quantification; a2DQ performs semi-automated border detection for cardiac chambers/vessels; aCMQ uses speckle-tracking for myocardial velocity, strain, and displacement; MVN provides task-guided segmentation for mitral valve structures; Heart Model enables one-click 3D volume quantification of cardiac chambers. Healthcare professionals review outputs (measurements, waveforms, bull's eye plots) to assess cardiac function (EF, volumes, wall motion). Modifications focus on workflow efficiency and semi-automation. Output assists clinicians in diagnostic decision-making; benefits include reduced analysis time and standardized quantification of cardiac parameters.
Clinical Evidence
Bench testing only. Verification and validation activities, including requirements review, design review, risk management, and system-level performance testing, confirmed that modified Q-Apps meet reliability and performance requirements relative to predicate devices.
Technological Characteristics
Software-based image processing application. Operates on standard PCs, dedicated workstations, or Philips ultrasound systems. Features include semi-automated border detection, speckle-tracking analysis, and 3D volume segmentation. Connectivity via standard ultrasound data formats. No specific hardware materials or energy sources; software-only modification.
Indications for Use
Indicated for trained healthcare professionals in clinical settings for the review and quantification of ultrasound image data acquired on Philips ultrasound systems.
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) Substantially Equivalent Devices
Philips Ultrasound believes that the modified QLAB a2DQ, aCMQ, MVN, and Heart Model Q-Apps are substantially equivalent to the previously cleared iU22 with 2DO (K042540), QLAB with MVQ (K070792), QLAB CMQ (K120525), and QLAB Heart Model (130159).
# 4) Device Description
QLAB Quantification software is available either as a stand-alone product that can function on a standard PC, on board a dedicated workstation, or on-board Philips' ultrasound systems. It can be used by trained healthcare professionals for the on-line and off-line review and quantification of ultrasound studies in healthcare facilities/hospitals.
The QLAB Quantification software application package is designed to view and quantify image data acquired on Philips ultrasound products. The four modified plug-ins, a2DO, aCMQ , MVN, and Heart Model are applications within Philips QLAB Quantification software.
{1}------------------------------------------------
# Automated 2D Quantification (a2DQ)
The 2DQ O-App for the display of 2D ultrasound images was originally submitted with Philips iU22 Ultrasound system (K042540). 2DQ has been renamed a2DQ. It computes areas, volumes and advanced parameters for LV systolic and diastolic function including: LV Ejection Fraction (EF), Peak Ejection Rate (PER), Peak Rapid Filling Rate (PRFR) and Atrial Filling Fraction (AFF). It also computes End Systolic Volume (ESV) and End Diastolic Volume (EDV). The Color Kinesis (CK) tool provides color-coded visualization of global and regional wall motion. a2DQ has been modified to improve workflows including semi-automated border detection for cardiac chambers and vessel cavities.
# Automated Cardiac Motion Quantification (aCMQ)
CMQ modifications were last addressed in QLAB 510(k) K120525. CMQ has been renamed aCMQ aCMQ provides an angle-independent analysis of regional myocardialtissue velocity, displacement, strain, and strain rate, using the speckle-tracking technology. It generates measurements of the global and regional functions and reports them in a table, a 17-segment bull's eye, and a variety of waveform displays. It additionally computes LV Ejection Fraction (EF), End Systolic Volume (ESV) and End Diastolic Volume (EDV). aCMQ has been modified to automatically draw a region of interest based on the selected anatomical view, (user can edit the ROI if desired).
## Mitral Valve Navigator (MVN)
The MVQ plug-in was submitted in QLAB 510(k) K070792. The application, renamed Mitral Valve Navigator (MVN), was originally designed as a manual segmentation interface that would allow for detailed segmentation of the mitral valve annulus, leaflets, and papillary muscle. However, as segmentation using the interface is entirely manual, the approximate time to complete the segmentation ranges from 5-15 minutes, depending on the user's familiarity with the interface, the quality of the image, and the user's knowledge of the mitral valve and experience in interpreting 3D echo images. The modification to MVN (MVQ) updates the application with improved task guidance and semi-automation for greater efficiency and ease of use. The modification focused primarily on decreasing the required workflow time by identifying bottlenecks in the workflow.
## Heart Model Quantification (HM)
The Heart Model O-App (K130159) provides one-click visualization of all four cardiac chambers, and quantifies the left ventricle (LV) and left atrium (LA) using a 3D Volume image from an apical four-chamber view. It provides the LV and LA volume, stroke volume, and LV ejection fraction (EF) at end-systole and end-diastole (ED) for adult hearts. It easily delivers the routine 2D views from the 3D volume. Measurements are closely correlated to cardiac MR and are exported to the report. The modified Heart Model application allows users to override border placement. The user may edit the border by clicking and dragging the border to the desired location. Numeric quantification will be updated based upon user placement of borders.
