Abstract
La presente invencion esta referida a un dispositivo de verificacion de posicionamiento que comprende una columna (1) que en su parte superior tiene un foco indicador (2) que tiene opcion encendido color verde y rojo. La columna (1) se fija a la camilla del Acelerador Lineal mediante tornillos (3) y soporta una estructura movil (4) la cual comprende: a) una estructura paralela a la camilla que esta unida a la columna (1); 4b) un brazo movil paralelo a la columna (1) que se ajusta a la estructura 4(a) mediante un tornillo (5); 4c) una base rectangular perpendicular a 4b), formando una "T" invertida, que tiene instalado siete sensores de voltaje (6) los cuales estan en contacto, uno a uno, con siete agujas (7) de cabeza redondeada en el extremo distal y en el extremo proximal es cilindrico hueco. Los sensores de voltaje (6) leen y emiten unas senales de voltaje segun la posicion vertical que adopten las agujas (7) sobre la superficie del paciente. Este dispositivo se adecua a la forma de la superficie de la zona a irradiar, obteniendo una curva de posicion (espectro) formado por las senales emitidas por los sensores de voltaje (6). Cada aguja con cabeza redondeada (7) es de libre movimiento y cae por gravedad y comprende en su interior filamentos (8) de 15cm de longitud de un material de baja resistencia electrica. Dichos filamentos (8) estan en contacto con el sensor de voltaje (6) cerrando el circuito de posicionamiento de las agujas. Los filamentos (8) estan insta lados en el interior de cada aguja (7) Todas las agujas (7) estan posicionadas en un mismo plano y estaran debidamente niveladas entre siThe present invention refers to a positioning verification device that comprises a column (1) that has an indicator light (2) in its upper part that has a green and red lit option. The column (1) is fixed to the stretcher of the Linear Accelerator by means of screws (3) and supports a mobile structure (4) which comprises: a) a structure parallel to the stretcher that is attached to the column (1); 4b) a movable arm parallel to the column (1) that is adjusted to the structure 4 (a) by means of a screw (5); 4c) a rectangular base perpendicular to 4b), forming an inverted "T", which has seven voltage sensors installed (6) which are in contact, one by one, with seven needles (7) with a rounded head at the distal end and at the proximal end it is hollow cylindrical. The voltage sensors (6) read and emit voltage signals according to the vertical position adopted by the needles (7) on the surface of the patient. This device adapts to the shape of the surface of the area to be irradiated, obtaining a position curve (spectrum) formed by the signals emitted by the voltage sensors (6). Each needle with a rounded head (7) is free to move and falls by gravity and comprises 15cm long filaments (8) of a material with low electrical resistance. Said filaments (8) are in contact with the voltage sensor (6) closing the circuit for positioning the needles. The filaments (8) are installed sides inside each needle (7) All the needles (7) are positioned in the same plane and will be properly leveled with each other
