IO-2 3D Virtual Simulator for Urology (Hu-Mo Simulator)
Specification: Urology 3D virtual simulator
Aims: Medical simulation techniques are going to be a part of mandatory process for training education. Enhancing and improving the quality of medical high-resolution images, three-dimensional (3D) visualization becomes possible and students' understanding can be improved in clinical practice and education. We aim extraction and reconstruction of 3D realistic anatomical models from CT/DICOM images with variable software packages and simulating them three dimensionally for educational purposes
Decrease the cost with using virtual based 3D models for surgical implementation and simulation, learning anatomy in medical fields specifically on urology, no more expensive machines and simulators
Using simulation technology for better understanding 3D surgical anatomy
Creating 3D medical simulator for virtual training (in laparoscopic/endoscopic)
Virtual training curriculum on medical models will be one of the target at the end of the Project
Medical 3D virtual reality technique is easily applicable to other clinic area.
The main advantage of 3D simulator, unlike in-vivo training, the entire procedure is completed in a risk-free environment without space-time constraints.
Methodology: Medical 3D simulation technology has resulted in exciting new solutions and possibilities of medical diagnosis and practice. The first step in developing a Medical 3D simulation is to reconstruct a DICOM file standardized with medical images from software package MIMICS, and to extract appropriate anatomical 3D model information such as STL. The second step to create a realistic human model is customizing the STL data with 3DS MAX and Z-Brush 3D model editing tool and texturing process using Photoshop to express realistic anatomical texture. The third step to visualization in virtual reality, a refined human 3D data is put into a virtual reality engine such as Unity 3D, and the simulator is completed through customization process like as program coding and interface device interlocking process.
Medical Image (CT/MRI) : Extraction of Computer Tomography (CT ) or Magnetic Resonance Imaging (MRI) data, from patients or cadavers with medical image device.
Dicom : Generating the Digital Imaging and Communications in Medicine (DICOM) files from CT/MRI with Mimics.
Segmentation : Mask the area of interest and extracting STL files with Mimics.
Modeling : 3D Surface treatment and texturing for realistic human & surgery tool model with 3DS MAX and Z-Brush
Library : 3D animated surgical movements with 3D controller and Building libraries of final 3D data with 3DS MAX and Z-Brush
Coding : Converting 3D data into VR engine and component Coding with Unity 3D
Simulator: Application publishing with Unity 3D

MedTRain3DModsim Urology 3D Simulator
European Board of Urology suggested 14 urologic procedures that need to make an assessment for evaluation resident’s skills. We selected 3 type urologic procedures that were included to the list of EBU to make 3D simulators as training purposes
1th Type : Standard Cystoscopy (flexible/rigid) simulator
2nd Type: Standard Retrograde Intrarenal Exploration (inspection of pelvicaliciel system/ relocation of stone with basket) simulator
3rd Type: Standard Laparoscopic Exploration for Nephrectomy (partial/total) simulator
