Abstract

Un densitometro de energía (10) incluye un detector de rayos X lineal de estado solido (13), el cual se puede barrer a través del paciente con el movimiento de un haz de abanico polienergético (23) de rayos X, para producir una imagen de densidad osea digital. Una placa de película de amplio espectro (25) interpuesta entre el detector (13) y el paciente, proporciona simultáneamente una imagen radiográfica de espectro completo de una alta resolucion y un bajo paralaje, tal como se puede utilizar para estudios morfométricos. Los espacios intervertebrales (40) se pueden utilizar para medir las alturas de las vértebras, las cuales se pueden combinar estadísticamente para proporcionar un estándar contra el cual se pueden detectar fracturas por aplastamiento.
