MNPS
is a program for planning stereotactic procedures, functional surgery
and radiosurgery. |
| |
MNPS
results from a 12-year-development of stereotactic procedure planning
techniques based on personal computers and neuroimages [1].
It began in 1990 with the name NSPS, and from
1994 to 2003 was distributed with the name of MSPS.
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, two stereotactic
atlases (Schaltenbrand-Wahren
and Talairach) 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. Take

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 trata stereo-tomography space as a rigid volume
and allows a slight plasticity in resonance volume (with control over
the módulo de rigidez). The algorythm is de domínio
3D, semi-automatic, not being critical in case of superposition of
partial volumes, and is stable when applied in images with artifacts
and retrospective studies.

There
are no principle limitations in mutual orientation of tomography and
resonance cuts to be fused.

The incorporation of such methods raises the safety of procedures,
lowers their invasion and reduces surgical time. |

Another
MNPS
resource is the module for Radiosurgery planning.
The MNPS
System can be configured for
different models of Stereotaxis and Radiosurgery
equipments |
