Abstract

In interventional radiology dose estimation using the interventional reference point IRP is a practical method for obtaining the realtime skin dose of a patient However the IRP is defined in terms of adult cardiovascular radiology and is not suitable for dosimetry of the head In the present study we defined a new reference point neuroIRP for neurointerventional procedures The neuroIRP was located on the central ray of the Xray beam 9 cm from the isocenter toward the focal spot To verify whether the neuroIRP was accurate in dose estimation we compared calculated doses at the neuroIRP and actual measured doses at the surface of the head phantom for various directions of the Xray projection The resulting calculated doses were fairly consistent with actual measured doses with the error in this estimation within approximately 15  These data suggest that dose estimation using the neuroIRP for the head is valid
