Este trabajo muestra una comparación básica en blancos geométricos circulares, esféricos, cilíndricos presentados en situaciones de radiocirugía estereotáctica (SRS) empleando sistemas de conos y micromultiláminas Larancio DMLCV de 3mm de doble focalización de la compañía Elekta 3Dline (mMLC), acelerador Sinergy Platform (Elekta-SP) con energía de 6MV, software ergo++(Ergo), phantom esférico Lucy 3D (PL3D) de la compañía Standard imaging con inserto para cámara de ionización CC01 y placas radiográficas, se usan placas gafcromic EBT3 (PG-EBT3) y software de análisis rit113 V6.1 (RIT); se programan circunferencias de 0,5 cm a 2,5cm en ambos sistemas de SRS buscando analizar en primera instancia penumbras, perfiles, curvas de Isodosis para ver el efecto de la doble focalización sobre los conos posteriormente se evalúa un blanco esférico de diámetro 1,3cm para realizar una planeación de 5 arcos cada uno de 100 grados de amplitud y separación de 30 grados de arco con los dos sistemas de SRS y finalmente se muestra un caso con imágenes de TAC donde se emplean las mismas especificaciones de configuración de arcos para analizar en Histograma de dosis volumen (DVH) índices de conformidad (IC) con el caso de una lesión de forma cilíndrica; se analiza el tiempo de planeación y para QA.
