THE PROBLEM A SOLUTION
THE PLOT THICKENS …. UNEXPECTED RESULTS
A NEW EQUIPMENT TO OFFER
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?
Ultra Sound Imaging
Used routinely by nephrologists Non ionizing Repeatable Affordable
But US imaging is
Usually only qualitative User dependant
Volume estimated by formula 2D image only for DICOM
Poor documentation for ECR
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
Design
NEFROVOL
Tests of NEFROVOL
Report for ECR in
CDA format
NEFROVOL to monitor volume
• Not very precise • Repeatability tests pending • Only indicative volume • Self reference of patient • Graph over months or years available
Difficulty with patient communication
• What if the volume is 3D printed ?
3D printer produced by:
Start up firm of Cochabamba, Bolivia
Support from the Bolivian:
Small Enterprise to intregrate NEFROVOL into IMPOVOL:
Start up firm of Montevideo, Uruguay
Design and Coordination
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.
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
By product
DICOM new object type: CT-like set of images for US
specifying number of cuts
What do you think of it?
Thank you !
