Brown T, Hogstrom K, Alvarez D, Ham K, Dugas J, Matthews 2nd K
Med Phys
. 2017 May;
39(6Part12):3738-3739.
PMID: 28517844
Purpose: This work investigates the dose-response curves of Gafchromic EBT2 and EBT3 radiochromic films using synchrotron-produced monochromatic x-ray beams. These dosimeters are being utilized for dose verification in photoactivated Auger...

Brown T, Hogstrom K, Alvarez D, Ham K, Matthews 2nd K
Med Phys
. 2017 May;
39(6Part11):3726.
PMID: 28517118
Purpose: This study performed a dosimetry intercomparison for synchrotron-produced monochromatic x-ray beams. Ion chamber depth-dose measurements in a polymethylmethacrylate (PMMA) phantom were compared with the product of MCNP5 Monte Carlo...

. 2017 Jan;
62(3):1172-1191.
PMID: 28092635
The goal of this work was to evaluate the accuracy of our in-house analytical dose calculation code against MCNPX data in heterogeneous phantoms. The analytical model utilizes a pencil beam...

Phys Med Biol
. 2005 Mar;
50(5):755-67.
PMID: 15798252
The laser wakefield acceleration (LWFA) mechanism can accelerate electrons to energies within the 6-20 MeV range desired for therapy application. However, the energy spectrum of LWFA-generated electrons is broad, on...

Kainz K, Hogstrom K, Antolak J, Almond P, Bloch C
Phys Med Biol
. 2005 Feb;
50(1):N1-10.
PMID: 15715431
Given that laser wakefield acceleration (LWFA) has been demonstrated experimentally to accelerate electron beams to energies beyond 25 MeV, it is reasonable to assess the ability of existing LWFA technology...

Kainz K, Hogstrom K, Antolak J, Almond P, Bloch C, Chiu C, et al.
Med Phys
. 2004 Aug;
31(7):2053-67.
PMID: 15305458
Laser wakefield acceleration (LWFA) technology has evolved to where it should be evaluated for its potential as a future competitor to existing technology that produces electron and x-ray beams. The...
