الوصف: Purpose: To determine if CT unit's estimated CTDI vol is statistically similar to values obtained using conventional medical physics testing and instrumentation. The ACR calculation spreadsheet was used to calculate the CTDI vol for each unit tested. Method and Materials: Exposure measurements were obtained from the center and 12 o'clock position for both a 32 cm diameter abdominal and 16 cm diameter acrylic head phantom. The measurements were made using axial scans for typical patient abdominal and head protocols. Five CT units were evaluated. Results: Examination of the results indicate good statistical agreement between the CT unit CTDI vol estimates and the ACR dose spreadsheet calculated CTDI vol . Conclusion: This work indicates that estimating patient dose (i.e., CTDI vol ) using CT unit values may be an accepted alternative to performing traditional measurements using acrylic phantoms.
