Accurate EVAR sizing is critical for procedural success. However, traditional manual planning is often time-consuming, prone to operator variability, and may lack precision. iSizing, fully automated sizing and planning software, addresses these challenges by improving accuracy, consistency and efficiency while maintaining full clinician oversight. Experience a new era of EVAR sizing and planning with iSizing.

Upload CT Scan & Visualise using MPR Viewer

To begin autosizing, simply upload the patient’s CT scan and instantly visualise the anatomy using the MPR Viewer. iSizing enables side-by-side comparison of the patient anatomy with a 3D model, providing a comprehensive anatomical overview.

Automated segmentation & Sizing measurements

iSizing performs fully automated segmentation including: Flow lumen, Thrombus, Calcifications. Additionally, iSizing also offers automated sizing measurements like baselines, lengths, and aortic diameters.‍

  1. ‍Baseline: iSizing provides 3 measurements like proximal baseline, right distal baseline, left distal baseline.‍
  2. Lengths: iSizing provides all the possible lengths for performing an accurate EVAR intervention planning.‍
  3. Diameters: iSizing provides above 20 diameters considering thrombus, calcification to provide accurate measurements with just a click.

This automated segmentation and sizing process not only significantly reduces planning time but also minimises inter-operator variability by providing consistent, reproducible measurements, there by enabling more efficient and reliable pre-procedural planning.

Interactive visualisation in intervention planning

iSizing introduces a unique approach to intervention planning, allowing you to select the optimal device from the catalogue, deploy it in real time, and interact with a 3D visualisation. It helps you assess the best fit for your patient’s anatomy and select appropriate extensions for ipsilateral and contralateral vessels.

You can also position the aorta to match your operative setup, facilitating C-arm angulation and supporting confident pre-procedural planning.

Generate sizing & planning report

Once you complete the planning process, you can save and download the sizing and planning report to share with your colleagues. As a cloud-based platform, iSizing allows you to perform your sizing and planning from anywhere, at any time.

We recognise that integrating new software into clinical practice can be challenging. Therefore, iSizing is designed to align closely with real-world clinical workflows. So we are offering five free trials so you can test iSizing and use it in your daily clinical practice.
