AROSCOPE

24.07.2016 This project explores the field of Augmented Reality (AR) overlay with a purpose-built surgical microscope (Leica M500-N) that tracked intraoperatively with an optical tracker (NDI Optotrak Certus). It is developed a medical application concept (AROSCOPE – Stereo Augmented Reality in a Navigated Surgical Microscope), which uses the platform independent open-source libraries. For the microscope embedded surgery the patient is registered with landmark-based registration technique and the head of microscope is navigated at the same time with the...

CTK in CAS

25.11.2013 CTK in CAS (The Common Toolkit in computer assisted surgery) is a medical open-source software that used to develop efficient, modular and plug-in based biomedical applications. And it provides a tutorial that can be used as a template by CTK plug-in framework e.g. for a standard navigation in CAS. Goal The goal of this project is as first, represent a template (demo application) using the CTK plug-in framework that facilitates and simplifies the creation of complex applications in the biomedical field in many ways, e.g. implementation and management...

Automatic Fiducial Detection

07.10.2013 Automatic Fiducial Detection is a tool for open4Dnav, which is developed with open-source libraries. It detects, localizes three dimensional (3D) objects (titanium balls) automatically in preoperative radiological images for given geometric object properties using morphological algorithms iteratively and allows geometric measurements, or computation operations by detected objects using a special filter. Goal The goal of the project is to develop an algorithm to identify/detect in the patient inserted and in the near of the surgical area positioned...

StoS

25.03.2012 StoS (Surface to Surface) is a medical open-source-tool for open4Dnav to realize a surface based (model based) registration with iterative closest point algorithm (ICP). The project goal is to get in the first step a point cloud (cartesian coordinate system) from segmented computed tomography data set (CT) by using the surface extraction technique, which is  used later as reference points for ICP. The second point cloud is recorded by the patient with a tracker by tracking the probe position, which is  used later as target points for the ICP. In the...

ViSeCut

04.03.2012 ViSeCut is a medical open-source computed tomography (CT) image viewing-, image processing- and image segmentation software that processes the read two-dimensional computed tomography  images (in DICOM format) by various imaging processes, methods and algorithms (volume rendering, watershed segmentation and region-growing segmentation) and represents the desired results. ViSeCut is implemented on Linux (Fedora 10) with programming language C++ and can be used and further expanded by integrating certain medical open-source/cross-platform libraries on...

CTTranslator

04.03.2012 CTTranslator is a medical open-source computed tomography (CT) image viewing and segmentation program, that processes the read three-dimensional CT images (in DICOM format) by various imaging processes methods (hounsfield skala) and applies the marching cubes algorithm for extracting a polygonal mesh of an isosurface from a three-dimensional scalar field and represents the desired results. CTTranslator is implemented on Linux (Fedora 10) with programming language C ++ and can be used later by integrating certain medical open-source/cross-platform...

GantryTilt0

04.03.2012 GantryTilt0 is a medical open-soruce software, which is used for correction (tilt angle, oblique view setting) of two-dimensional DICOM-formatted computed tomography (CT) images using shear effect of affine transformation. The goal of project was to read the CT images with a -6° tilt angle (shear factor), to bring it by the displacement or shear transformation at 0° gantry tilt in 3D coordinate system and to save transformed CT images again as a CT series, so that the CT images stands ready for later geometrical measurements, registration with other...

mimimiC

04.03.2012 mimimiC is a compiler that reads in the C programming language written source codes analyzes, compiles and executes. The goal of this project was it to develop and implement a compiler in programming language C. The compiler is written complete in C and accepts an input language, which is strongly ajar against C programming language. The input language of the compiler is a subset of C. With it the most important features of C are supported. mimimiC is a native multi-pass compiler, and generates RISC code for the virtual machine. The compiler is...
