TOMTEC-ARENA

TOMTEC-ARENA (TTA2.40) is a clinical software package designed to support diagnosis by enabling comprehensive quantification and reporting of cardiovascular, fetal, and abdominal structures using multi-dimensional medical image data. It employs advanced image processing, including 3D/4D modeling, speckle tracking, and machine learning algorithms, to provide detailed functional and morphological assessments for enhanced clinical decision-making.

TOMTEC-ARENA (TTA2.40) is an advanced clinical software package designed for the comprehensive review, quantification, and reporting of cardiovascular, fetal, and abdominal structures and functions from multi-dimensional digital medical data. Its primary purpose is to support physicians in diagnosing patients with suspected diseases by providing detailed analyses and measurements. The system comprises various modules, including 4D analysis tools for the left ventricle (LV), right ventricle (RV), and mitral valve (MV), as well as 2D cardiac performance analysis for adult and fetal hearts, and AutoStrain capabilities for LV, LA, and RV. It integrates with different imaging platforms, facilitating workflow through database management, data import/export, and archiving for reporting and statistical quantification. The software employs sophisticated image processing techniques, including 3D/4D modeling, speckle tracking for strain analysis, and machine learning algorithms for automated or semi-automated contour generation and landmark proposal, particularly in its 4D RV-Function, 4D MV-Assessment, and 4D LV-Analysis modules. Key updates in version TTA2.40 involve enhanced measurements (e.g., LA strain, additional MV parameters, renal vascular metrics), workflow improvements for user convenience, integration of new technologies like HeartModel auto-segmentation, and expansion of capabilities such as fetal cardiac analysis within 2D CPA and browser support for IMAGE-COM. Non-clinical testing confirmed that these modifications meet design and performance requirements, ensuring the software remains safe and effective for its intended clinical applications.
