The sectioned images (SIs) of the pelvis from a female cadaver are the best source of realistic threedimensional (3D) models of the female urogenital system. The purpose of this research is to present SIs and outlined images of the female pelvis with improved quality, which may be used to produce 3D models to simulate virtual dissection or surgery of the female urogenital and adjacent structures. A pelvis of Korean female cadaver which preserved buttock curve was scanned with 3T MR and CT machines. The pelvis was embedded and milled at 0.1 mm intervals. All sectioned surfaces were photographed to create horizontal SIs. On the Photoshop, 73 structures were outlined in the SIs to create outlined images. Once the structures were outlined, volume and surface models of the structures could be produced. A total of 222 MRIs and 222 CTs of a female pelvis were obtained. 2,220 SIs of the pelvis were obtained (0.1×0.1×0.1mm3-sized voxels; 48 bits color). 222 outlined images of 73 structures were prepared at 1mm intervals. Once the structures were outlined, 3D volume and surface models of the structures were produced without the help of the computer programmers using MRIcro and Maya software. We have produced high quality SIs of the female pelvis accompanied by corresponding MRI and CT images. 3D volume and surface models of the female pelvic structures have been constructed. These computerized models may serve as the basis for future realistic medical simulation programs that may enhance clinical understanding of pelvic anatomy.
Abstract
The sectioned images (SIs) of the pelvis from a female cadaver are the best source of realistic threedimensional (3D) models of the female urogenital system. The purpose of this research is to present SIs and outlined images of the female pelvis with improved quality, which may be used to produce 3D models to simulate virtual dissection or surgery of the female urogenital and adjacent structures. A pelvis of Korean female cadaver which preserved buttock curve was scanned with 3T MR and CT machines. The pelvis was embedded and milled at 0.1 mm intervals. All sectioned surfaces were photographed to create horizontal SIs. On the Photoshop, 73 structures were outlined in the SIs to create outlined images. Once the structures were outlined, volume and surface models of the structures could be produced. A total of 222 MRIs and 222 CTs of a female pelvis were obtained. 2,220 SIs of the pelvis were obtained (0.1×0.1×0.1mm3-sized voxels; 48 bits color). 222 outlined images of 73 structures were prepared at 1mm intervals. Once the structures were outlined, 3D volume and surface models of the structures were produced without the help of the computer programmers using MRIcro and Maya software. We have produced high quality SIs of the female pelvis accompanied by corresponding MRI and CT images. 3D volume and surface models of the female pelvic structures have been constructed. These computerized models may serve as the basis for future realistic medical simulation programs that may enhance clinical understanding of pelvic anatomy.
