The purpose of this Special 510(k) Pre-Market Notification is to expand the Smart View Select (SVS) software application onto the Affiniti Series Diagnostic Ultrasound Systems and to modify the Smart View Select software application onto both the EPIQ Series Diagnostic Ultrasound Systems. Smart View Select is an automated software feature that assists the user in selection of images for analysis with the existing Philips AutoStrain LV or 2D Auto LV application in Adult Echo Transthoracic (TTE) examination. This feature automatically classifies each acquired image by view and selects an appropriate set of images for left ventricle (LV) analysis. The classification is based on a Deep Learning AI interface engine; the selection is a non-AI algorithm that considers the view classification and image depth to select the optimal set of images. No hardware changes to the EPIQ or Affiniti systems are required when using SVS, and existing, cleared Philips TTE transducers are used with these software applications. The SVS v2 feature is supported by all EPIQ models running software version 13.0 or higher including EPIQ CVx/CVxi, EPIQ Elite Advanced, EPIQ Elite, EPIQ 7, EPIQ 5. The SVS v2 feature is supported by the Affiniti models running software version VM13.0 or higher, including Affiniti CVx, Affiniti 70, Affiniti 50, and Affiniti 30. The SVS and SWM software features are associated with the cardiac adult indication.

The R-Trigger algorithm software feature on Philips EPIQ and Affiniti Ultrasound System is intended to support detection of R-wave peak (R-trigger) as an input to certain TTE clinical applications, initially including AutoStrain LV, AutoEF, 2D Auto LV (collectively referred to as "AutoStrain"), and AutoMeasure applications. The R-trigger algorithm is planned to be implemented as workflow enhancement for transthoracic clinical applications on EPIQ and Affiniti Ultrasound Systems in the VM13 software release. The Auto-Measure and AutoStrain features support users during B-mode (2D), CW-, PW- and TDI-Doppler measurements by automating some of the measurements needed to complete a routine transthoracic echo (TTE) exam for adult patients. The R-trigger feature (non-ECG-based) has been developed to enable clinical users to use AutoMeasure and AutoStrain application without the R-trigger (ECG based) input, which is currently required. There are no hardware changes to the EPIQ and Affiniti systems due to change to the introduction of the R-Trigger software application. The software application is supported by all EPIQ and Affiniti models running software version 13.0 or higher.

The purpose of this Special 510(k) Pre-Market Notification is to modify the Segmental Wall Motion and introduce Auto EF with contrast software application onto the Philips EPIQ Series Diagnostic Ultrasound System and Affiniti Series Diagnostic Ultrasound Systems. SWM algorithm was previously cleared (K243862) and Auto EF contrast algorithm(K243235) was also previously cleared. The current software release version VM 13, replaces the previous version of the segmental wall motion algorithm included in version 11 of the software release with the current cleared version (K243862) without any modifications, and integrates Auto EF contrast algorithm(K243235) without any modifications into one software release. The SWM v2 software automatically evaluates the segmental (regional) function of the left ventricle (LV) from adult TTE echo examinations. For input, the SWM algorithm uses 3 apical views (A4C, A2C and A3C) and performs border detection and tracking to identify each of the LV segments based on the three views. The SWM v2 software is a semi-automated quantitative imaging algorithm, as users are generally expected to review and concur with the initial and generated results. The users can also manually edit algorithm-generated segmental wall motion scores for individual segments based on their clinical expertise. Auto EF with contrast is an AI based automated software feature that assists clinicians with assessing Left Ventricular Ejection Fraction (LVEF) from images acquired with contrast agent as part of an adult transthoracic echo (TTE) examination. The feature is located within the Philips Auto EF Adv application. Auto EF with contrast uses 2 apical views (Apical four chamber view (A4C), Apical two chamber (A2C)) and provides EF for each view and a biplane Simpsons EF. No hardware changes to the EPIQ or Affiniti systems were made due to the SWM v2 and Auto EF with contrast, and existing, cleared Philips TTE transducers are used with these software applications.

The Flash Ultrasound System 5100 Point of Care (POC) device is constructed with assets from the previously cleared 5000 Compact Series hardware platform (K222648) and a new Rhythm software platform that is new to the POC environment. The Flash Ultrasound System 5100 POC supports a full touch screen interface on the main display as the primary means of directing the system, leveraging customer familiarity with smart devices and the ease of cleaning and maintenance of a pure glass surface. Additionally, Flash Ultrasound System 5100 POC is designed to fit into tight spaces in a crowded Emergency Room (ER) with its small footprint, sleek design, and a large vertical tablet with ergonomic controls. The new Rhythm software offers point-of-contact workflow enhanced with assisted needle visualization, streamline point-of-care workflows such as flexible patient data management and AutoStrain EF. In addition to these POC workflows, the Rhythm software provides enhanced responsiveness with an easy-to-learn user interface as all controls are located in the same plane as the user's eye and hand for working more efficiently with the patient. The Flash Ultrasound System 5100 POC has two models, the 5100 POC and the 5100 POC Pro. The 5100 POC version does not support two transducers, C5-1 and X8-2t; however, the 5100 POC Pro supports all the transducers listed for the system.

The purpose of this Traditional 510(k) Pre-market Notification is to introduce the SWM, 3D Auto TV and 3D Auto CFQ software applications as well as compatibility of VeriSight ICE / Pro ICE Probe data with the subject device Ultrasound Workspace Version 6.0. The semi-automated Segmental Wall Motion feature (SWM) evaluates the segmental (regional) function of the left ventricle (LV) from adult TTE echo examinations. It performs border detection and tracking to identify each of the LV seqments, provides segmental wall motion scores for each segments of the LV by using machine learning algorithms and calculates an overall wall motion score index (WMSI) as the average of the segmental scores. 3D Auto TV software enables semi-automated quantification of the tricuspid valve. At a high level, this is accomplished through automatically derived measurements from a segmented model of the tricuspid valve annulus formed by the software through model-based segmentation of the acquired ultrasound images. 3D Auto CFQ provides semi-automated quantification of Mitral Requrgitation (MR) volume and peak flow rate based on 3D color flow images. This application uses a known fluid dynamic model of flow that is adapted to the acquired color information. This allows quantitative assessment of mitral valve leakage during systole. The derived result supports the assessment of mitral regurgitation volume and peak flow rate. Data Compatibility of the VeriSight ICE / Pro ICE Probe, transducers cleared for the EPIQ Series Diagnostic Ultrasound System (K202216), will be introduced for Ultrasound Workspace 6.0. General software architecture of the previously cleared version TOMTEC-ARENA remains unchanged. Two new clinical application packages will be introduced with UWS6.0: 3D Auto TV and 3D Auto CFQ. An existing feature AutoStrain Left Ventricle (AutoStrain LV) gains additional functionality by integration of Segmental Wall Motion (SWM) feature. The module using AutoStrain LV together with SWM is named 2D Auto LV.

The purpose of this Traditional 510(k) Pre-Market Notification is to introduce the Auto Measure Artificial Intelligence-Machine Learning software feature onto the 5000 Compact Series Ultrasound Systems. The Auto Measure feature utilizes machine learning to provide a subset of semi-automated and editable measures during an echocardiography or when reviewing an already acquired echocardiography. When Auto Measure Version 2 is enabled, the healthcare professional performs an echocardiography with a workflow that provides the user with a semi-automated measurement that can be edited, accepted, or rejected.
