escala de grises. ○ Escala Hounsfield: arbitrariamente asigna a cada tono de gris un número. ○ EJEMPLO: UH aire, + UH hueso,. 0 agua. O número de TC é a normalização dos coeficientes de atenuação com o coeficiente de atenuação da água. A unidade é Hounsfield em homenagem ao. Nas regiões centrais da escala Hounsfield [ ] (por exemplo, água, 0 de separação em unidades Hounsfield (UH), realizados em pacientes normais, [ ].
