Journal ArticleDOI
Defining the role of radiosurgery in the management of brain metastases.
Minesh P. Mehta,Jack M. Rozental,Allan B. Levin,Thomas R. Mackie,Shrikant S. Kubsad,Mark A. Gehring,Timothy J. Kinsella +6 more
TL;DR: It is concluded that stereotactic radiosurgery can be used effectively in patients with brain metastases and associated with improved quality of life as measured by Karnofsky score, neurologic function, and steroid dependence.
Journal ArticleDOI
Investigation of the convolution method for polyenergetic spectra.
TL;DR: The distribution of absolute dose per unit fluence from polyenergetic photon beams impinging upon a water phantom was calculated using two convolution approaches that properly account for beam hardening effects.
Journal ArticleDOI
Minimization of small bowel volume within treatment fields utilizing customized "belly boards".
Thomas G. Shanahan,Minesh P. Mehta,Kathleen L Bertelrud,Delores A. Buchler,Lori E Frank,Mark A. Gehring,Shrikant S. Kubsad,Paul C Utrie,Timothy J. Kinsella +8 more
TL;DR: All patients were found to benefit from this prone "belly board" setup regardless of body habitus, weight, and age, and this technique is comfortable, inexpensive, highly reproducible, and permits maximal bowel displacement from standard pelvic radiotherapy fields.
Journal ArticleDOI
Treatment of arteriovenous malformations with stereotactic radiosurgery employing both magnetic resonance angiography and standard angiography as a database
Daniel G. Petereit,Minesh P. Mehta,P A Turski,Allan B. Levin,Charles M. Strother,Charles A. Mistretta,Rock Mackie,Mark A. Gehring,Shrikant S. Kubsad,Timothy J. Kinsella +9 more
TL;DR: Early analysis suggests that slower flowing arteriovenous malformations may obliterate faster after stereotactic radiosurgery and flow parameters could be employed to predict response, and magnetic resonance angiography permits semiquantitative flow velocity assessment and may therefore be superior to stereOTactic angiographies.
Journal ArticleDOI
Monte Carlo and convolution dosimetry for stereotactic radiosurgery.
Shrikant S. Kubsad,T. Rockwell Mackie,Mark A. Gehring,David J. Misisco,Bhudatt R. Paliwal,Minesh P. Mehta,Timothy J. Kinsella +6 more
TL;DR: The dosimetry of small photon beams used for stereotactic radiosurgery was investigated using Monte Carlo simulation, convolution calculations, and measurements.
