AcculCAS is software intended to be used for performing calculations in X-ray angiographic images of the intracranial vessels. AcculCAS enables neurointerventionalists to obtain quantifications of one or more lesions in the analyzed intracranial vessel segment. In particular, Accul CAS provides:
Quantitative results of intracranial vessel segments based on a 3D reconstructed model;
Dimensions of the intracranial vessels and lesions;
Quantification of the pressure gradient (PG) and pressure ratio (PR) in intracranial vessels.
AcculCAS is indicated for use in clinical settings where validated and reproducible quantitied results are needed to support the assessment of intracranial vessels in X-ray angiographic images.
When the quantified results provided by Accul CAS are used in a clinical setting on X-ray images of an individual patient, the results are only intended for use by the responsible clinicians.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
