Shepard A, Frigo S
J Appl Clin Med Phys
. 2021 Mar;
22(3):216-223.
PMID: 33666339
Purpose: To assess the implementation, accuracy, and validity of the dosimetric leaf gap correction (DLGC) in Mobius3D VMAT plan calculations. Methods: The optimal Mobius3D DLGC was determined for both a...

Shepard A, Mittauer K, Bayouth J, Yadav P
J Appl Clin Med Phys
. 2020 Oct;
21(12):54-61.
PMID: 33119933
Purpose: Dark current radiation produced during linac beam-hold has the potential to lead to unplanned dose delivered to the patient. With the increased usage of motion management and step-and-shoot IMRT...

Jupitz S, Shepard A, Hill P, Bednarz B
J Appl Clin Med Phys
. 2020 Jun;
21(8):183-190.
PMID: 32533758
Intrafraction imaging-based motion management systems for external beam radiotherapy can rely on internal surrogate structures when the target is not easily visualized. This work evaluated the validity of using liver...

Shepard A, Matrosic C, Radtke J, Jupitz S, Culberson W, Bednarz B
Med Phys
. 2018 Sep;
45(11):4816-4821.
PMID: 30220085
Purpose: Latencies for motion management systems have previously been presented as guidelines for system development and implementation. These guidelines consider the overall system latency, including data acquisition, algorithm processing, and...

Shepard A, Bender E
J Radiosurg SBRT
. 2018 Jan;
4(3):225-234.
PMID: 29296447
Purpose: To develop a fundamentally new stereotactic radiosurgery (SRS) collimator design which utilizes initially off-axis Compton scattered photons to increase the dose rate at isocenter for small field treatments. Materials...

Shepard A, Wang B, Foo T, Bednarz B
Med Phys
. 2017 Sep;
44(11):5889-5900.
PMID: 28898419
Purpose: The implementation of motion management techniques in radiation therapy can aid in mitigating uncertainties and reducing margins. For motion management to be effective, it is necessary to track key...
