Journal ArticleDOI
The management of respiratory motion in radiation oncology report of AAPM Task Group 76.
Paul J. Keall,Paul J. Keall,Gig S. Mageras,James M. Balter,Richard S. Emery,Kenneth Forster,Steve B. Jiang,Jeffrey M. Kapatoes,Daniel A. Low,Martin J. Murphy,Brad Murray,Chester R. Ramsey,Marcel van Herk,Sastry Vedam,John Wong,Ellen Yorke +15 more
TL;DR: The magnitude of respiratory motion is described, radiotherapy specific problems caused by respiratory motion are discussed, techniques that explicitly manage respiratory motion during radiotherapy are explained, and recommendations in the application of these techniques for patient care are given.
Journal ArticleDOI
Respiration-correlated spiral CT: a method of measuring respiratory-induced anatomic motion for radiation treatment planning.
TL;DR: RCCT scans can be used in connection with respiratory-gated treatment to identify the patient-specific phase of minimum tumor motion, determine residual tumor motion within the gate interval, and compare treatment plans at different phases.
Journal ArticleDOI
The deep inspiration breath-hold technique in the treatment of inoperable non–small-cell lung cancer
Kenneth E. Rosenzweig,Joseph Hanley,Dennis Mah,Gig S. Mageras,Margie Hunt,Sean Toner,Chandra Burman,C. Clifton Ling,Borys Mychalczak,Zvi Fuks,Steven A. Leibel +10 more
TL;DR: The DIBH technique provides an advantage to conventional free-breathing treatment by decreasing lung density, reducing normal safety margins, and enabling more accurate treatment.
Journal ArticleDOI
Four-dimensional (4D) PET/CT imaging of the thorax.
Sadek Nehmeh,Yusuf E. Erdi,Tinsu Pan,Alex Pevsner,Kenneth E. Rosenzweig,Ellen Yorke,Gig S. Mageras,Heiko Schöder,Phil Vernon,Olivia Squire,Hassan Mostafavi,Steven M. Larson,John L. Humm +12 more
TL;DR: 4D PET/CT is clinically a feasible method, to correct for respiratory motion artifacts in PET/ CT imaging of the thorax, and can reduce smearing, improve the accuracy in PET-CT co-registration, and increase the measured SUV.
Journal ArticleDOI
Effect of respiratory gating on reducing lung motion artifacts in PET imaging of lung cancer
Sadek Nehmeh,Yusuf E. Erdi,C. Clifton Ling,Kenneth E. Rosenzweig,Olivia Squire,Louise E. Braban,Eric C. Ford,K. Sidhu,Gig S. Mageras,Steven M. Larson,John L. Humm +10 more
TL;DR: This study was conducted as a proof of principle that a gating technique can effectively reduce motion artifacts in PET image acquisition.
