Intended Use

VitreaAdvanced is a medical diagnostic system for the processing, review, analysis, communication and media interchange of multi-dimensional digital images acquired from a variety of imaging devices. VitreaAdvanced is not meant for primary image interpretation in mammography. It can be used with a variety of cleared Vitrea® based software applications. In addition, VitreaAdvanced includes three Vitrea® applications: Vitrea CT Body Perfusion is a noninvasive post-processing application designed to evaluate perfusion of organs and tumors. The software can calculate perfusion characteristics from dynamic CT image data acquired after the injection of contrast media. The software also allows the separate calculation of the arterial and venous components of perfusion in organs. It supports evaluation of regions of interest and the visual inspection of time density curves. When used by a trained and qualified physician a potential application is to differentiate blood flow between normal and diseased tissue. Determination of the change of perfusion parameters during the course of treatment may be helpful in therapy monitoring. Vitrea CT Liver Analysis is a noninvasive post-processing application designed to evaluate liver tumors and plan for liver surgery. It displays images for analysis and preoperative liver surgery planning, such as organ segmentation, tumor segmentation and intrahepatic vessels segmentation, as well as the approximation of vascular territories. It supports preoperative evaluation of specific surgery strategies by allowing the user to interactively define virtual resections splitting the liver. It also allows the user to evaluate safety-margins around lesions and to identify affected vascular branches and territories. Vitrea® CT Liver Analysis also provides automatic registration of multiple series and measurement tools for characterization and follow-up of the lesions. When used by a trained and qualified physician a potential application is to assist in the assessment of tumor response to therapy. Vitrea CT Brain Perfusion is a noninvasive post-processing application designed to evaluate areas of brain perfusion. The software can calculate cerebral blood flow (CBF), cerebral blood volume (CBV), local bolus timing (i.e., delay of tissue response, time to peak), and mean transit time (MTT) from dynamic CT image data acquired after the injection of contrast media. The package also allows the calculation of regions of interest and mirrored regions, as well as the visual inspection of time density curves. Vitrea® CT Brain Perfusion supports the physician in visualizing the apparent brain tissue perfusion affected by acute stroke. Areas of decreased perfusion, as is observed in acute cerebral infarcts, appear as areas of changed signal intensity (lower for both CBF and CBV and higher for time to peak and MTT).

Device Story

VitreaAdvanced is a software-only post-processing platform for multi-dimensional digital images (CT). It receives DICOM data; allows interactive 2D/3D/4D visualization, annotation, and measurement; and outputs processed views to printers or DICOM devices. Used in clinical settings by physicians/technologists. Includes three specialized applications: 1) CT Body Perfusion: calculates perfusion characteristics (blood flow) from dynamic CT scans using maximum slope (Fick principle) to differentiate tissue types and monitor therapy. 2) CT Liver Analysis: performs organ/tumor/vessel segmentation, virtual resection planning, and RECIST/WHO reporting for surgical planning and tumor response. 3) CT Brain Perfusion: calculates CBF, CBV, MTT, and bolus timing via deconvolution to visualize perfusion deficits in acute stroke. Physicians use these outputs to characterize anatomy/pathology and guide clinical decision-making. Benefits include improved visualization of perfusion and standardized surgical/treatment planning.

Clinical Evidence

No clinical studies required. Evidence consists of bench testing, including verification of software requirements, risk management, and performance testing using imaging phantoms to validate spatial accuracy and measurement tools. External validation involved qualitative assessment by cardiologists, radiologists, and 3D technicians who confirmed clinical acceptability, workflow integration, and visual similarity of results to existing scanner-based or predicate software.

Technological Characteristics

Software-only medical device for standard IT hardware. Complies with DICOM (NEMA PS 3.1-3.18). Features include image segmentation (rigid/deformable registration, region growing), perfusion analysis (maximum slope, deconvolution), and measurement tools. Connectivity via DICOM. Cybersecurity via Windows-based authentication and audit logging.

Indications for Use

Indicated for processing, review, and analysis of multi-dimensional digital images from various imaging devices. Used by trained physicians for: 1) Body Perfusion: evaluating organ/tumor perfusion and therapy monitoring; 2) Liver Analysis: liver tumor evaluation, surgical planning, and tumor response assessment; 3) Brain Perfusion: evaluating brain perfusion in acute stroke patients. Not for primary mammography interpretation.

Device Name: VitreaAdvanced

#### Indications for Use:

VitreaAdvanced is a medical diagnostic system for the processing, review, analysis, communication and media interchange of multi-dimensional digital images acquired from a variety of imaging devices. VitreaAdvanced is not meant for primary image interpretation in mammography. It can be used with a variety of cleared Vitrea® based software applications. In addition, VitreaAdvanced includes three Vitrea applications:

Vitrea® CT Body Perfusion is a noninvasive post-processing application designed to evaluate perfusion of organs and tumors. The software can calculate perfusion characteristics from dynamic CT image data acquired after the injection of contrast media. The software also allows the separate calculation of the arterial and venous components of perfusion in organs. It supports evaluation of regions of interest and the visual inspection of time density curves. When used by a trained and qualified physician a potential application is to differentiate blood flow between normal and diseased tissue. Determination of the change of perfusion parameters during the course of treatment may be helpful in therapy monitoring.

Vitrea® CT Liver Analysis is a noninyasive post-processing application designed to evaluate liver tumors and plan for liver surgery. It displays images for analysis and preoperative liver surgery planning, such as organ segmentation, tumor segmentation and intrahepatic vessels seqmentation, as well as the approximation of vascular territories. It supports preoperative evaluation of specific surgery strategies by allowing the user to interactively define virtual resections splitting the liver. It also allows the user to evaluate safety-margins around lesions and to identify affected vascular branches and territories. Vitrea® CT Liver Analysis also provides automatic registration of multiple series and measurement tools for characterization and follow-up of the lesions. When used by a trained and qualified physician a potential application is to assist in the assessment of tumor response to therapy.

Vitrea CT Brain Perfusion is a noninvasive post-processing application designed to evaluate areas of brain perfusion. The software can calculate cerebral blood flow (CBF), cerebral blood volume (CBV), local bolus timing (i.e., delay of tissue response, time to peak), and mean transit time (MTT) from dynamic CT image data acquired after the injection of contrast media. The package also allows the calculation of regions of interest and mirrored reqions, as well as the visual inspection of time density curves. Vitrea® CT Brain Perfusion supports the physician in visualizing the apparent blood perfusion in brain tissue affected by acute stroke. Areas of decreased perfusion, as is observed in acute cerebral infarcts, appear as areas of changed signal intensity (lower for both CBF and CBV and higher for time to peak and MTT).
