Impact of Anode heel effect on entrance surface dose of ovaries in lumbosacral spine radiography: phantom study

Objectives: The aim of this research was to study the impact of heel effect on entrance surface dose (ESD) of ovaries in lumbosacral radiography with two orientations of the phantom in terms of tube axis. Methods: Siemens Multix Top general radiography system was used. Imaging exposure factors we...

Methods: Siemens Multix Top general radiography system was used. Imaging exposure factors were chosen as, 77 kVp and 32 mAs for anteroposterior (AP) and 79 kVp and 40 mAs for lateral lumbosacral examination. An anthropomorphic whole-body phantom PBU-50 was scanned. Each set of projection was obtained in two different orientations of the phantom, i.e., head was positioned in the direction of cathode end, and then it was placed towards the anode end of the X-ray tube. Optically stimulated luminescent dosimeters (OSLDs) were used to measure ESD at ovaries site. Results: When the phantom’s feet were placed to the cathode end of the X-ray tube in AP and lateral projections, mean dose received by the ovaries was 31.4% and 42.9% higher than the opposite orientations of phantom, respectively. Conclusion: Patients head must be positioned near the cathode side to achieve substantial reduction in radiation dose to ovaries. 2019-08 Conference or Workshop Item PeerReviewed application/pdf en http://irep.iium.edu.my/77654/1/Abstract_ICMHS2019.pdf application/pdf en http://irep.iium.edu.my/77654/2/ICMHS2019-E-Poster_MC192_10082019.pdf Sayed, Inayatullah Shah and Rahmat, Nur Izzah Syahira (2019) Impact of Anode heel effect on entrance surface dose of ovaries in lumbosacral spine radiography: phantom study.
