title = "Evaluation of skin-dose contribution from a new high-definition image receptor mode during neuro-interventional procedures using the Dose Tracking System",
abstract = "A new image receptor has recently been introduced that has a standard flat-panel detector (FPD) mode as well as a highdefinition (Hi-Def) zoom mode. The Dose Tracking System (DTS), which our group has developed, has been expanded in functionality to allow for the analysis of the skin-dose contribution of the Hi-Def mode during fluoroscopic interventional procedures. A clinical version of the DTS records all geometric and exposure technique parameters from a digital interface on the Canon Biplane Angiography System during interventional procedures in log files. Previous work on the enhancement of our group's DTS led to the development of a replay function which facilitates playback of the log files. Within the replay feature, modifications have been made to allow for separate evaluation of exposures from each detector mode as identified by signals for the magnification (MAG) mode being used. The current work utilizes this separation method for neuro-interventional cases performed with the new image receptor to retrospectively analyze dose related contributions from the Hi-Def mode as compared to FPD usage. Peak skin dose (PSD) and dose area product (DAP) were evaluated for six clinical cases under IRB approval. Three de-identified log files were also included in order to demonstrate the method for separation of PSD as well as the variation with procedure types. Ratios of FPD PSD and DAP to Hi-Def values were determined for a subset of three cases during which the new image receptor was implemented.",
