System for planning stereotactic procedures, functional neurosurgery, stereotactic brachytherapy and multimodal fusion of images. It has versions for the main stereotactic frames available in the market, with automatic recognition of fiducial markers. It allows to perform the multimodal fusion of images for CT, MRI and PET with Maximization of the Mutual Information and the fusion with several functional stereotactic atlases.
The MNPS program is the result of more than 20 years of development of planning techniques for stereotactic procedures based on personal computers and neuroimaging and has support for the main stereotactic frames available in the market.
All techniques are tridimensional (3D) and based on the parametrization of each tomographic, magnetic resonance and stereotactic angiography section plane.
In order to ease functional surgery procedure planning, several stereotactic atlases were digitalized to vectorial shape and various resources incorporated to achieve the maps overlay over reformatted stereo-tomographies slices. Many parameters guarantee control over the atlas space orientation in relation to the patient's brain, being the anterior and the posterior commissure essential to that.
In order to include magnetic resonance to the plan, lowering the impact of its geometric distortion, a multimode image fusion technique was created. This method considers stereo-tomography space as a rigid volume and allows a slight plasticity in resonance volume (with control over the módulo de rigidez).
