Rapid (6.0)

The iSchemaView Rapid (6.0) platform is a medical image management and processing system designed to assist clinicians in rapidly analyzing CT and MRI scans for diagnosing conditions, with a key indication for selecting acute stroke patients for endovascular thrombectomy. It operates by processing DICOM-compliant image data through specialized modules (e.g., CTP, DWI, CTA) to visualize and quantify tissue characteristics such as perfusion, diffusion, and vessel occlusion, streamlining complex analyses in time-critical situations.

The iSchemaView Rapid (6.0) is an advanced software package designed for medical image management and processing, intended for use by trained professionals like physicians and medical technicians. Its primary purpose is to facilitate the visualization, quantification, analysis, and reporting of tissue changes using digital images from CT and MRI diagnostic systems, thereby aiding in diagnosis. A significant application of Rapid CT-Perfusion and MR-Perfusion modules is to assist physicians in selecting acute stroke patients, specifically those with known intracranial internal carotid artery or proximal middle cerebral artery occlusions, for endovascular thrombectomy, provided they meet clinical requirements and have no contraindications such as poor bolus quality, excessive motion artifacts, or hemorrhage. The Rapid platform functions as a Software as a Medical Device (SaMD), installable on a customer's server or accessible as a virtual system, in on-premises or hybrid (on-premises/cloud) configurations. It processes DICOM-compliant medical image data acquired from various sources, automatically identifying the scanning modality to apply suitable processing modules like Rapid CTP/MRP, DWI, CTA, and ASPECTS for analyses including volumetry, time-intensity plots, and mismatch measurements. The system is engineered to streamline time-consuming image processing tasks with minimal user interaction, featuring an image processing engine and a central iSchemaView Server for encrypted data storage and secure access, supporting critical decision-making in clinical workflows, particularly for time-sensitive conditions.

• Q1. How does the Rapid platform's algorithm for selecting acute stroke patients for endovascular thrombectomy account for variations in imaging protocols or scanner types across different institutions?; What are the specific performance metrics (e.g., sensitivity, specificity, processing time) of the individual modules like Rapid CTA or Rapid ICH in real-world clinical settings beyond the provided validation data?; How does the hybrid (on-premises/cloud) configuration impact data security, processing speed, and integration with existing hospital IT infrastructure compared to a fully on-premises deployment?; Can the Rapid platform quantify the evolution of ischemic changes over time by comparing serial scans, and what is the reliability of such longitudinal analysis?; Beyond identifying contraindications like hemorrhage or poor bolus quality, does the software provide any quantitative assessment of scan quality to guide reprocessing or reacquisition?
