EVALUATION OF A HEAD-REPOSITIONER AND Z-PLATE SYSTEM FOR IMPROVED ACCURACY OF DOSE DELIVERY

Autor: Sarah C. Charney, Mary K. Klein, Wendell R. Lutz, Pamela D Jones

Publikováno v: Veterinary Radiology & Ultrasound. 50:323-329

Radiation therapy requires accurate dose delivery to targets often identifiable only on computed tomography (CT) images. Translation between the isocenter localized on CT and laser setup for radiation treatment, and interfractional head repositioning

Accurate setup of paraspinal patients using a noninvasive patient immobilization cradle and portal imaging

Autor: Yoshiya Yamada, D. Michael Lovelock, Zvi Fuks, Mark H. Bilsky, Margie Hunt, Kamil M. Yenice, P Wang, Howard Amols, Sean Toner, Wendell R. Lutz, Nathalie Fournier-Bidoz, Chiaho Hua

Publikováno v: Medical Physics. 32:2606-2614

Because of the proximity of the spinal cord, effective radiotherapy of paraspinal tumors to high doses requires highly conformal dose distributions, accurate patient setup, setup verification, and patient immobilization. An immobilization cradle has

A block design for split-field tests of accelerator alignment

Autor: Wendell R. Lutz, Eric C. Ford

Publikováno v: Medical Physics. 31:2331-2334

We present a block design that facilitates split-field tests, a technique frequently employed to assess several potential misalignments in linear accelerators. Two tests are possible with this device using: (1) opposed collimator angles and (2) oppos

Publikováno v: International Journal of Radiation Oncology*Biology*Physics. 55:583-593

Purpose: To design and implement a noninvasive stereotactic immobilization technique with daily CT image-guided positioning to treat patients with paraspinal lesions accurately and to quantify the systematic and random patient setup errors occurring

Development of a semi-automatic alignment tool for accelerated localization of the prostate

Autor: Michael J. Zelefsky, Matthew S. Katz, Gikas S. Mageras, Chiaho Hua, C. Clifton Ling, D. Michael Lovelock, Wendell R. Lutz, James Mechalakos, Timothy Hollister, Eugene P. Lief

Publikováno v: International Journal of Radiation Oncology*Biology*Physics. 55:811-824

Purpose: Delivering high dose to prostate with external beam radiation has been shown to improve local tumor control. However, it has to be carefully performed to avoid partial target miss and delivering excessive dose to surrounding normal tissues.

Relative profile and dose verification of intensity-modulated radiation therapy

Autor: Jenghwa Chang, C. Clifton Ling, Chen S. Chui, Gikas S. Mageras, Wendell R. Lutz

Publikováno v: International Journal of Radiation Oncology*Biology*Physics. 47:231-240

Purpose: To develop a quality assurance (QA) procedure to assess the intensity profile and dosimetry for intensity-modulated (IM) treatment fields using electronic portal imaging devices (EPIDs). Methods and Materials: A series of rapidly acquired (�

Publikováno v: International Journal of Radiation Oncology*Biology*Physics. 45:603-611

Purpose/Objective: This study evaluates the dosimetric benefits and feasibility of a deep inspiration breath-hold (DIBH) technique in the treatment of lung tumors. The technique has two distinct features—deep inspiration, which reduces lung density

Determination of effective electron source size using multislit and pinhole cameras

Autor: Eugene P. Lief, Wendell R. Lutz

Publikováno v: Medical physics. 27(10)

Two independent methods have been utilized for determination of effective source sizes for 6, 12, and 20 MeV electron beams generated by a Varian 2100C linear accelerator. First, a multislit camera has been constructed using parallel aluminum plates
