Abstract
APARATO DE IMPRIMIR PARTICULARMENTE ADECUADO PARA PROPORCIONAR UNA COPIA PERMANENTE DE UNA IMAGEN PRODUCIDA POR EQUIPO MEDICO DE IMAGEN O SIMILAR. EL METODO CREA UNA COPIA PERMANENTE POR MODULACION DE ZONA CON UN GRAN NUMERO DE NIVELES DE GRIS POR CADA ZONA DE MODULACION DE AREA (PIXEL) GENERANDO EN COLIMNAS SUBSTANCIALMENTE ADYACENTES UNIDADES DE SUBPIXELES LLAMADAS PELS. LOS PELS TIENEN UN TAMAÑO INICIAL QUE SE INCREMENTA POR LA ADICION DE SUBPELS, DENOMINADOS LONCHAS.
