The document describes a new technique called NEFROVOL to non-invasively estimate kidney volume from ultrasound images. NEFROVOL involves using ultrasound to capture parallel 2D images of the kidneys, defining boundaries in each image, building a 3D mesh, and extrapolating to estimate total volume. There is also a plan to integrate NEFROVOL with a new system called IMPOVOL that will 3D print models of patients' kidneys to help doctors better communicate with patients about their condition and plan for surgery or treatment. Initial tests of NEFROVOL's accuracy have been mixed but the hope is refining the technique and 3D printing kidneys will improve patient outcomes.

IMPOVOL Reconstruction of Anatomical Structures from UltraSound Slices and 3D Print
- 1. IMPOVOL Reconstruction of Anatomical Structures from UltraSound Slices and 3D Print Prof. Franco Simini Universidad de la República – URUGUAY Bin@Sheffield, 10-12 Nov 2014
- 2. THE PROBLEM A SOLUTION THE PLOT THICKENS …. UNEXPECTED RESULTS A NEW EQUIPMENT TO OFFER
- 3. THE PROBLEM • Kidneys with polyquistosis are difficult to measure • Renal volume is needed for follow up • CT scan cannot be repeated How can renal volume be estimated non invasively?
- 4. Ultra Sound Imaging Used routinely by nephrologists Non ionizing Repeatable Affordable
- 5. But US imaging is Usually only qualitative User dependant Volume estimated by formula 2D image only for DICOM Poor documentation for ECR
- 6. NEFROVOL Parallel 2D images along main axis User to define boundaries in each 2D Build a mesh Extrapolate at the ends Count contained elements Use scale to estimate volume
- 7. Design
- 8. NEFROVOL
- 23. Report for ECR in CDA format
- 24. NEFROVOL to monitor volume • Not very precise • Repeatability tests pending • Only indicative volume • Self reference of patient • Graph over months or years available
- 25. Difficulty with patient communication • What if the volume is 3D printed ?
- 28. 3D printer produced by: Start up firm of Cochabamba, Bolivia
- 29. Support from the Bolivian:
- 30. Small Enterprise to intregrate NEFROVOL into IMPOVOL: Start up firm of Montevideo, Uruguay
- 32. NEFROVOL is a project of nib in cooperation with Nephrology Department of Hospital de Clínicas: Mauro Sitrin, Esteban Arrua, D.I. Luciana Urruty, Dr. Oscar Noboa, Dr. Diego Tobal e Ing. Franco Simini. La Impresora 3D es un desarrollo de SAWERS, Cochabamba, en una iniciativa de cooperación de la Universidad Mayor San Simón de Bolivia y de la Universidad de la República. La integración y distribución son de Bullseye, Montevideo. Setiembre 2014.
- 33. IMPOVOL • It is a new idea • Give a PVC model of an inner organ to MDs for interaction with patients, not just a standard organ • Give a real reproduction of organs for surgery planning, instruction, strategic decisions, reconstruction, tc
- 34. By product DICOM new object type: CT-like set of images for US specifying number of cuts
- 35. What do you think of it?
- 37. Thank you !
