Riassunto
Come in tutti i sistemi di imaging medicale che utilizzano radiazioni ionizzanti, lo scopo dell’operatore che esegue una scansione TC è massimizzare la qualità delle immagini riducendo il più possibile la dose assorbita dal paziente, ovvero raggiungere il miglior equilibrio tra qualità delle immagini necessaria per un dato quesito diagnostico e dose radiante. Per raggiungere tale obiettivo si può agire sul processo di scansione modulando opportunamente una serie di parametri, che si possono classificare a seconda delle fasi della scansione in cui essi intervengono (acquisizione, elaborazione e visualizzazione, come anticipato nel Capitolo 3); molti di questi parametri sono peraltro stati in parte introdotti nei precedenti capitoli.
