Is there Correlation between Measured and Console CTDI_vol in Multislice CT Scanners?

Allen Nathan Mhagama*

This study investigated the relationship between measured and console volume computed tomography dose index (CTDI_vol) in multislice CT scanners. The measured CTDI values were determined from kerma length product measured using pencil ionization chamber inserted in the holes of standard CT phantoms with diameters 16 and 32 cm, which respectively mimic adult head and body using the procedures recommended by International Electro-technical Commission. Significantly large deviations were observed between the measured and console CTDI_vol values in multislice CT scanners.
