Evaluation of therapeutic radiographer contouring for magnetic resonance image guided online adaptive prostate radiotherapy
Adair Smith G, Dunlop A, Alexander S, Barnes H, Casey F, Chick J, et al.
Radiother Oncol . 2023 Jan; 180:109457. PMID: 36608770
Background And Purpose: The implementation of MRI-guided online adaptive radiotherapy has facilitated the extension of therapeutic radiographers' roles to include contouring, thus releasing the clinician from attending daily treatment. Following...

Dosimetric comparison of automatically propagated prostate contours with manually drawn contours in MRI-guided radiotherapy: A step towards a contouring free workflow?
Sritharan K, Dunlop A, Mohajer J, Adair-Smith G, Barnes H, Brand D, et al.
Clin Transl Radiat Oncol . 2022 Sep; 37:25-32. PMID: 36052018
Background: The prostate demonstrates inter- and intra- fractional changes and thus adaptive radiotherapy would be required to ensure optimal coverage. Daily adaptive radiotherapy for MRI-guided radiotherapy can be both time...

Bladder filling in patients undergoing prostate radiotherapy on a MR-linac: The dosimetric impact
Adair Smith G, Dunlop A, Barnes H, Herbert T, Lawes R, Mohajer J, et al.
Tech Innov Patient Support Radiat Oncol . 2022 Mar; 21:41-45. PMID: 35243043
The implementation of adaptive radiotherapy for prostate cancer compensates for inter-fraction motion, at the penalty of increased time in room. The subsequent increase in bladder filling may impact dosimetry, which...

Online adaptive radiotherapy for head and neck cancers on the MR linear Accelerator: Introducing a novel modified Adapt-to-Shape approach
Gupta A, Dunlop A, Mitchell A, McQuaid D, Nill S, Barnes H, et al.
Clin Transl Radiat Oncol . 2021 Dec; 32:48-51. PMID: 34849412
Introduction: The Elekta Unity MR-Linac (MRL) has enabled adaptive radiotherapy (ART) for patients with head and neck cancers (HNC). Adapt-To-Shape-Lite (ATS-Lite) is a novel Adapt-to-Shape strategy that provides ART without...

Inter-Observer Variation in Delineating the Pharyngeal Constrictor Muscle as Organ at Risk in Radiotherapy for Head and Neck Cancer
Petkar I, McQuaid D, Dunlop A, Tyler J, Hall E, Nutting C
Front Oncol . 2021 Mar; 11:644767. PMID: 33768005
Background And Purpose: To evaluate the inter-observer variation (IOV) in pharyngeal constrictor muscle (PCM) contouring, and resultant impact on dosimetry and estimated toxicity, as part of the pre-trial radiotherapy trial...

Voluntary versus ABC breath-hold in the context of VMAT for breast and locoregional lymph node radiotherapy including the internal mammary chain
Ranger A, Dunlop A, Grimwood A, Durie E, Donovan E, Havilland J, et al.
Clin Transl Radiat Oncol . 2021 Mar; 27:164-168. PMID: 33681483
Background: Deep-inspiration breath-hold (DIBH) reduces radiation dose to the heart in patients undergoing locoregional breast radiotherapy. In the context of tangential irradiation of the breast/ chest wall, a voluntary breath...

Geometric and dosimetric evaluation of the differences between rigid and deformable registration to assess interfraction motion during pelvic radiotherapy
White I, McQuaid D, McNair H, Dunlop A, Court S, Hopkins N, et al.
Phys Imaging Radiat Oncol . 2021 Jan; 9:97-102. PMID: 33458433
Background And Purpose: Appropriate internal margins are essential to avoid a geographical miss in intensity-modulated radiation therapy (IMRT) for endometrial cancer (EC). This study evaluated interfraction target motion using rigid...

Feasibility of MR-guided ultrahypofractionated radiotherapy in 5, 2 or 1 fractions for prostate cancer
Mohajer J, Dunlop A, Mitchell A, Goodwin E, Nill S, Oelfke U, et al.
Clin Transl Radiat Oncol . 2020 Nov; 26:1-7. PMID: 33241129
The drive towards hypofractionated prostate radiotherapy is motivated by a low alpha/beta ratio for prostate cancer (1 to 3 Gy) compared to surrounding organs at risk, implying an improved therapeutic...

The impact of restricted length of treatment field and anthropometric factors on selection of head and neck cancer patients for treatment on the MR-Linac
Ng-Cheng-Hin B, Nutting C, Newbold K, Bhide S, McQuaid D, Dunlop A, et al.
Br J Radiol . 2020 May; 93(1111):20200023. PMID: 32436787
Objective: This study investigates the impact of a restricted craniocaudal (CC) field length of <20 cm on the selection of head and neck cancer (HNC) patients who can be treated...

Daily adaptive radiotherapy for patients with prostate cancer using a high field MR-linac: Initial clinical experiences and assessment of delivered doses compared to a C-arm linac
Dunlop A, Mitchell A, Tree A, Barnes H, Bower L, Chick J, et al.
Clin Transl Radiat Oncol . 2020 May; 23:35-42. PMID: 32395640
Introduction: MR-guided adapted radiotherapy (MRgART) using a high field MR-linac has recently become available. We report the estimated delivered fractional dose of the first five prostate cancer patients treated at...
