The VMS+ 4.0 system is an adjunct to existing ultrasound imaging systems and is intended to record, analyze, store and retrieve digital ultrasound images for computerized 3-dimensional image processing. The VMS+ 4.0 system is indicated for use where Left Ventricle (LV), Left Atrium (LA), and Right Atrium (RA) volumes and ejection fractions are warranted or desired.

The Ventripoint VMS+ 4.0 System is a medical imaging device designed to assist clinicians in evaluating cardiac function through 3D reconstruction of heart chambers. It uses a Knowledge-Based Reconstruction (KBR) algorithm to recreate the heart's shape by capturing 2D ultrasound images at specific angles and referencing a database of MRI heart shape catalogs. The reconstructed 3D heart models are used to calculate volumes of any of the four chambers at end-diastolic and/or end-systolic phases. The software can also be installed on a separate workstation to import 3D datasets, MRI studies, and VMS+ studies. The system employs user-driven anatomical control point placement to generate 3D models. Users manually adjust control points based on an anatomical template aligned with the patient's ultrasound images. An edge detection algorithm refines these points to match detected anatomical boundaries, ensuring model precision. The VMS+ system includes a hardware stand with a computer, position sensors to track the 3D orientation of the ultrasound transducer and patient movement, and software to handle image capture, landmark placement, and reconstruction. By leveraging its sensor system and statistical shape analysis, the VMS+ transforms 2D ultrasound data into accurate 3D models. The workflow takes approximately 15 minutes and provides detailed volumetric data and reports for clinical review.
