Create 3D data and model from medical (DICOM) data

2D continuous slice image data taken by CT or MRI is output in DICOM file format.
This DICOM file cannot be directly used as 3D CAD data.
The DICOM files is converted into 3D data by applying a variety of softwares.
Then, the converted data are to be corrected as they are neither be output to as 3D data

Extracting and editing data on a brain

Extracting data on brain involves difficulties, due to different threshold values the upper and lower parts and membranes being attached, hence, data, when used as 3D data, requires various correction processes.

1Unnecessary objects are removed from 3D CAD data of entire brain

2Data of brain only is extracted and smoothed after noise is eliminated

33D CAD data of brain completed

43D Printer output a 3D model, based on 3D data of brain

Extracting and editing data of blood vessel

Extracting all necessary 3D data of blood vessel in a single process also involves a high level of difficulties, due to different threshold values in the upper and lower parts as it is with brain. Data are collected little by little by controlling values to be extracted.

1Extracting blood vessel data begins.

Blood vessel data extracted for the 1st time

2Data are extracted while thresholds values are controlled.

Required data continue to be extracted while controlling values to be extracted until data collection is completed.

3Data for arteries and veins are separated and collected.

Artery
Vein

4Coordinates of arteries and veins are combined

5A visualized model, prepared, based on the completed 3D data of blood vessels, is output from 3D printer.
