MNPS: History. |
||||
| From its begining the planning system was distributed or commercialized under three different names: |
| NSPS: This was its name from the time of the first lines of code, written in Havana in 1990, and it remained NSPS until 1994. The first module created was for a Riechert-Mundinger (manufactured by Fischer) stereotactic apparatus, including geometry and image processing capabilities. An additional module for radiosurgery with multiple arcs were introduced right after the first one; starting with coplanar arcs and immediately augmented for non-coplanar arcs radiosurgery. A third module was developed for stereotactic brachytherapy planning with Iridium 192 wires and Iodine 125, 6702/6711, seeds (both from Amerscham). In 1992 the geometric model of the system was modified to support the Leksell G system (manufactured by Elekta AB.) . At that time we created a digital and vectorial version of the Schaltenbrand-Warhen and Talairach atlases that was incorporated to NSPS. Between 1993 and 1994 several papers were published in specialized journals with details about the system and its applications. In October, 1993 the system and various of its clinical applications were presented at the “XI Meeting of the World Society for Stereotactic and Functional Neurosurgery”. |

MSPS:Since May, 1994, the name “MSPS” was adopted to comercialize the system through Micromar (Micromar Industria e Comercio Ltda. , Diadema, SP, Brasil). A third geometry was introduced for an apparatus manufactured by Micromar, called ETM01, that closely resembled a Hitchcock frame as the one that follows. |

After the introduction of Micromar’s ETM03 model, a fourth geometry was created inside MSPS to support the new apparatus.
The radiosurgery module was also modified to support the hardware manufactured by Micromar. |

MNPS:In 2003 the system was ported to Windows 2000 and XP, using Microsoft DirectDraw interface, and became “MNPS”. The new system supports bigger image matrixes, so that the accuracy of the stereotactic coordinate calculations was enhanced. Several modules were improved such as the stereo-angiography, radiosurgery and multimodality image matching. Radiosurgery arcs templates were incorporated. The 3D renderization windows was optimized, mainly from the performance point of view. A new tool for quantitative evaluation of radiosurgery plans was developed, the dose-volume histogram (DVH). MNPS is able to detect, support and optimize for new Intel’s technologies such as SSEx and HT. Support for various native image formats from CTs , MRI, PET and SPECT was added. The conformance statement for the DICOM interface was enhanced. | ||
