Advanced Medical Visualization
In daily clinical practice different post-processing techniques can be used to represent all the information related to anatomical scan data, acquired by CT, PET or TAC instrumentation. Most Medical Imaging software applications, which support medical experts in the 3D reconstruction of anatomical structures coming from DICOM images, are capable of offering a threedimensional visualization of all volumetric data with a high degree of accuracy. However, even if some medical applications present VR facilities for 3D model visualization, they usually do not provide the natural 3D interaction methods necessary to benefit completely from Virtual Environments (VEs).
In order to enhance usability, traditional input interfaces should be replaced with more user-friendly human-computer interaction interfaces. In particular, a 3D User Interface (UI) should allow the user to act in a way similar to real life, making it possible to exploit human abilities in a virtual environment. Thus, to reach this goal, the user has to interact through non-obstructive devices. Moreover, more than one mode of input should be used to make the human-computer interaction more natural and intuitive.
