Description
Technical field
The present invention relates to a kind of method of the 3D of structure numeral brain model, relate in particular to a kind of method of the tomoscan picture being carried out the three-dimensional brain model of three-dimensional reorganization formation.
Background technology
Nervous System Anatomy is a complicated medical science form science of the various space structure of content; Particularly basis cranii and brain dissect abstract hard to understand be the teaching and clinical practice in outstanding problem and where the shoe pinches; Traditional method is to utilize two-dimentional means such as chalk, blackboard, teaching material, wall chart, projection to explain, and carries out the sample teaching then and cultivates the doctor.Clinically, cerebral cortex and brain DEEP STRUCTURE are the basic positions that neurosurgery is organized work, but cerebral cortex and deep nuclei space structure thereof are very complicated; Be difficult to clear assurance exactly; Therefore the neurosurgeon usually uses head two-dimensional scan planar graph information, according to the brain anatomical knowledge, and abstract reconstruct brain three-dimensional information; In a single day deviation appears in reconstruct, will form mistake and risk.
Therefore, make up the visual brain model of 3-dimensional digital that fidelity is high, the error probability is little, help neurosurgery and select rational operation pathway, effectively instruct the neurosurgery clinical practice, also help the teaching of medical colleges and schools.
People such as Wei Na are in " based on the brain model three-dimensional rebuilding method research of Visualization Toolki " (Chinese rehabilitation theory and practice; 2005 the 11st the 3rd phases of volume; 167 ~ 169 pages) measurement data based on CT is disclosed in the literary composition; Utilize visualization tool bag Visualization Toolki to combine VC to realize medical image three-dimensional visualization, rebuild head model; On this basis, Zhang Shuli etc. have visually carried out detailed introduction to what utilize that Visualization Toolki carries out the CT image in " utilize VTK realize medicine CT image three-dimensional visualization " (Qiqihar Medical College's journal, the 9th phase of 2006 phases) literary composition.
But brain is different with head, and brain is a part of structure of head.Method with rebuilding head can not built brain.Because it is the difficulty that said method can't overcome that brain is separated from head.Therefore moreover as far as all brain structures, head MRI (magnetic resonance imaging) is much clear than head CT, need be based on the construction method of the three-dimensional brain model of MRI image.
