Commissioning kilovoltage cone-beam CT beams in a radiation therapy treatment planning systemParham Alaei
Department of Radiation Oncology, University of Minnesota, Minneapolis, MN 55455, USA
J Appl Clin Med Phys 13:3971. 2012..Inclusion of this dose in treatment plans can lead to more accurate dose prediction, especially when the doses to organs at risk are of importance...
Effect of multileaf collimator-defined segment size on S(c)Parham Alaei
Department of Therapeutic Radiology Radiation Oncology, University of Minnesota, Minneapolis, Minnesota 55455, USA
Med Phys 37:2731-7. 2010..In the case of IMRT treatments, however, the jaw is often set at a fixed size, and the MLCs form the segments, or control points, of each beam, thus the difference between MLC and jaw settings may be significant...- The accuracy of inhomogeneity corrections in intensity modulated radiation therapy planning in Philips Pinnacle systemParham Alaei
Department of Therapeutic Radiology Radiation Oncology, University of Minnesota, Minneapolis, MN 55455, USA
Med Dosim 36:240-5. 2011.... - Inclusion of the dose from kilovoltage cone beam CT in the radiation therapy treatment plansParham Alaei
University of Minnesota, Minneapolis, Minnesota 55455, USA
Med Phys 37:244-8. 2010..The daily use of CBCT could lead to accumulated patient doses higher than the older technique of weekly portal imaging. There have been several studies focusing on measurement or calculation of the patient dose from CBCT recently... - In vivo diode dosimetry for IMRT treatments generated by Pinnacle treatment planning systemParham Alaei
Therapeutic Radiology, University of Minnesota, Minneapolis, MN 55455, USA
Med Dosim 34:26-9. 2009.... - The use of a commercial QA device for daily output check of a helical tomotherapy unitParham Alaei
Department of Therapeutic Radiology Radiation Oncology, University of Minnesota, Mayo Mail Code 494 420 Delaware Street S E, Minneapolis, Minnesota 55455, USA
Med Phys 33:3680-2. 2006..This device can also be used to monitor the constancy of beam energy and cone profile and can potentially be used to detect gross errors in the couch movement or laser alignment... - Performance evaluation and quality assurance of Varian enhanced dynamic wedgesParham Alaei
Department of Therapeutic Radiology Radiation Oncology, University of Minnesota, Minneapolis, Minnesota 55455, USA
J Appl Clin Med Phys 7:14-20. 2006..The results of the 18-month evaluation show reproducibility in the wedge factors of better than 1% and in dose profiles of better than 2% on a monthly basis. Daily output measurements are generally within 2% of expected values... - Implementation of enhanced dynamic wedges in Pinnacle treatment planning systemParham Alaei
Department of Therapeutic Radiology Radiation Oncology, University of Minnesota, Minneapolis, MN 55455, USA
Med Dosim 30:228-32. 2005..The process of data collection and verification, beam modeling, and a discussion of a potential pitfall encountered in this process are presented in this paper... - Comparison of dynamic and step-and-shoot intensity-modulated radiation therapy planning and deliveryParham Alaei
University of Minnesota, Minneapolis, MN 55455, USA
Med Dosim 29:1-6. 2004.... - The effect of small field output factor measurements on IMRT dosimetryRezvan Azimi
Department of Therapeutic Radiology Radiation Oncology, University of Minnesota, Minneapolis, Minnesota 55455, USA
Med Phys 39:4691-4. 2012..To evaluate how changes in the measured small field output factors affect the doses in intensity-modulated treatment planning...
