Determinação das coordenadas na tomografia computadorizada estereotáxica: simplificação do método convencional

Abstract: RESUMO -Apresenta-se uma simplificação dos métodos gráfico e aritmético usualmente utilizados para determinação das coordenadas estereotáxicas de um alvo na tomografia computadorizada. O cálculo aritmético, além de mais simples, é teoricamente mais preciso por medir as coordenadas do alvo a partir de um ponto real do espaço estereotáxico. O diagrama (método gráfico) proposto apresenta a vantagem de permitir a determinação das coordenadas estereotáxicas do alvo independentemente do tamanho das imagens da tomogr… Show more

“…This surgical procedure is performed with a geometric orientation device fixed on the head, which directs the instrument to the coordinates of the target, increasing the precision of neurosurgery and reducing brain damage. 5,50 In the 1940s, the Austrian neurologist Ernest A. Spigel and the American neurosurgeon Henry T. Wycis performed stereotactic surgery in humans using dorsomedial thalamotomy in schizophrenic patients for the first time. Their technique increased the accuracy of neurosurgery and decreased brain damage.…”
