Intended Use

syngo Circulation is a self-contained image analysis software package for evaluating cardiac CTA volume data sets. syngo Circulation combines commercially available digital image processing and visualization tools (MIP thin/thick, MPR thin/thick, VRT, CPR), evaluation tools (volumetric analysis of the left ventricle, coronary tree segmentation and stenosis evaluation) and reporting tools (lesion location and characteristics) with a workflow including dedicated scanning protocols. The software package is designed to support the physician in confirming the presence or absence of physician identified coronary lesions and evaluation of the hearts functional parameter in addition to evaluation, documentation and follow-up of any such lesions. These visualization/evaluation tools allow for volumetric analysis of the left ventricle and characterization of coronary lesions over time, helping the physician to assess the changes. It is also designed to help the physician classify conspicuous regions of tissue unambiguously, with respect to their size, dimensions, shape and position.

Device Story

syngo Circulation is a software package for cardiac CTA volume data analysis; inputs include cardiac CTA volume data sets. Device utilizes digital image processing and visualization tools (MIP, MPR, VRT, CPR) to perform volumetric analysis of the left ventricle, coronary tree segmentation, and stenosis evaluation. Output includes visualization, quantification, and reporting of lesion location/characteristics and functional parameters. Used in clinical settings by physicians to confirm presence/absence of coronary lesions, evaluate cardiac function, and document/follow-up on lesions over time. Assists physicians in classifying tissue regions by size, dimension, shape, and position. Supports clinical decision-making by providing quantitative data for longitudinal assessment of coronary changes.

Clinical Evidence

No clinical data provided. Safety and effectiveness are supported by hazard analysis, software verification, and validation testing.

Technological Characteristics

Software-based image analysis package. Features visualization tools (MIP, MPR, VRT, CPR), volumetric analysis, and coronary tree segmentation. Operates on cardiac CTA volume data. Software development follows recognized industry standards for risk management and hazard control.

Indications for Use

Indicated for use by physicians to analyze cardiac CTA volume data sets, including volumetric analysis of the left ventricle, coronary tree segmentation, stenosis evaluation, and characterization/follow-up of coronary lesions.

Regulatory Classification

Identification

A computed tomography x-ray system is a diagnostic x-ray system intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data from the same axial plane taken at different angles. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.
