Step map
Instead of relying on a single generic AI model, this pipeline connects specialized tools to maximize quality. First, you'll use Sonavex to baseline 3d map and quantitative metrics of the av fistula are captured and stored for longitudinal comparison. Then, you pass the output to Sonavex to a validated 3d vessel map with accurate lumen boundaries and diameter/depth annotations is ready for clinical interpretation. Then, you pass the output to Sonavex to cannulation sites are precisely planned and marked, reducing the risk of infiltration, hematoma, or vessel damage. Then, you pass the output to Sonavex to longitudinal change detection provides objective evidence of fistula maturation or complications, enabling timely intervention. Then, you pass the output to Sonavex to proactive, data-driven surveillance reduces unplanned access failures and hospitalizations. Finally, Sonavex is used to all stakeholders have a shared, visual understanding of the access health, enabling informed decisions and coordinated care.
Initial Patient Setup and Baseline 3D Ultrasound Acquisition
Baseline 3D map and quantitative metrics of the AV fistula are captured and stored for longitudinal comparison.
Automated Segmentation and Vessel Mapping
A validated 3D vessel map with accurate lumen boundaries and diameter/depth annotations is ready for clinical interpretation.
Cannulation Site Planning and Needle Guidance
Cannulation sites are precisely planned and marked, reducing the risk of infiltration, hematoma, or vessel damage.
Serial Maturation Monitoring with Automated Change Detection
Longitudinal change detection provides objective evidence of fistula maturation or complications, enabling timely intervention.
Long-Term Access Health Tracking and Predictive Alerts
Proactive, data-driven surveillance reduces unplanned access failures and hospitalizations.
Clinical Reporting and Shared Decision-Making
All stakeholders have a shared, visual understanding of the access health, enabling informed decisions and coordinated care.
Position the patient with the AV fistula arm comfortably extended. Use the Sonavex ultrasound probe to acquire a full 3D volumetric scan of the fistula, including inflow artery, anastomosis, and outflow vein. Ensure consistent anatomical landmarks (e.g., distance from wrist or elbow) are recorded for future co-registration.
Why Sonavex: Sonavex is the only tool in the menu that directly provides 3D ultrasound acquisition, vessel mapping, and volumetric flow measurement for dialysis access management.
Upload the acquired 3D volume to the Sonavex software platform. The AI algorithm automatically segments the vessel lumen, identifies the anastomosis, and generates a color-coded 3D vessel map with diameter and depth annotations. Review the segmentation for accuracy and manually correct any misidentified boundaries.
Why Sonavex: Sonavex includes AI segmentation and vessel mapping capabilities specifically designed for dialysis access, directly matching the step's needs.
Using the 3D vessel map, identify optimal cannulation zones (straight segments with diameter >6mm, depth <10mm, and no adjacent stenosis). Mark the skin entry points with a surgical marker. Optionally, use the Sonavex real-time needle guidance overlay to visualize the needle tip relative to the vessel center during cannulation.
Why Sonavex: Sonavex directly supports cannulation site planning and needle guidance for dialysis access, with vessel mapping and flow measurement.
Schedule follow-up scans at weeks 2, 4, 6, and 8 post-fistula creation. Acquire a new 3D volume at each visit using the same anatomical landmarks. The Sonavex software automatically co-registers the new volume with the baseline and highlights changes in diameter, depth, and flow. Review the change report for signs of stenosis, aneurysm, or inadequate maturation.
Why Sonavex: Sonavex is designed for serial monitoring of arteriovenous fistula maturation with automated change detection and volumetric flow measurement.
Continue periodic 3D ultrasound surveillance (e.g., monthly for mature fistulas). The Sonavex platform aggregates all historical scans and applies a predictive model to estimate risk of access failure (e.g., based on declining flow, increasing stenosis). Set automated alerts for when metrics cross thresholds (e.g., flow drops below 400 mL/min or diameter decreases by 2mm).
Why Sonavex: Sonavex provides longitudinal analytics and predictive monitoring for dialysis access health, directly supporting long-term tracking and alerts.
Generate a comprehensive report summarizing the 3D vessel map, maturation trajectory, and risk assessment. Share the report with the patient and the dialysis care team (nephrologist, surgeon, dialysis nurse). Use the visual 3D map to explain the access status and collaboratively decide on cannulation strategy, intervention timing, or access revision.
Why Sonavex: Sonavex includes a reporting module for clinical documentation and can integrate with EHR systems for shared decision-making.
§ Before you start
Teams or solo builders working on healthcare tasks who want a repeatable process instead of one-off tool experiments.
No. Start with the top pick for each step, then replace tools only if they do not fit your pricing, compliance, or output needs.
Open the mapped task page and compare top options side by side. Prioritize output quality, integration fit, and predictable cost before scaling.
