P24.07: Case report: umbilical cord true knot diagnosed by 3D power Doppler

Abstract

Electronic poster abstractsimage: 3D volume to 2D dicom images using DICOMatic (TomoVision).Step 2. Pre-processing: Gaussian filter for reducing the noise of 2D cross-section.Step 3. Iterative Binary method: applied different thresholds for each image in consideration of the characteristics of each section (2D image) to separate only the region of the fetus.Step 4. Post-processing: morphologic operation applied for segmentation of the meaningful area of the fetus.Step 5. Modeling and visualization: smoothing after surface rendering. 3D model was provided in the form of a stl file after completing all processing. Results: We applied these algorithms for 3D ultrasound volume data of fetal face and fetal heart between 19 and 29 completed gestational weeks. We successfully created 3D printing of fetal face and fetal heart with commercial 3D printer. Conclusions: Preliminary experiments indicate good results in image segmentation from 3D ultrasound data and 3D printing of fetus. It can be used for numerical analysis and creation of a physical model by 3D Printer.
