Increasing demands on commissioning and quality assurance for cone-based multiple brain metastases robotic radiosurgery: evaluation in a custom phantom

Godfrey Mukwada, Pejman Rowshanfarzad, Martin A. Ebert

CyberKnife stereotactic radiosurgery (SRS) treatment of multiple brain metastases (MBM) using fixed cone collimation is well established. This study aims to rigorously evaluate the commissioning of MBM SRS using feasible complex clinical scenarios. Sixteen gross tumour volumes (GTVs) were contoured on the …

Development and validation of a 3D-printed dosimetry phantom for paediatric radiology

Jonathon Stone, Pejman Rowshanfarzad, Adriano Polpo, C. L. Williams et autres

Abstract Radiation dosimetry is essential in the optimisation and justification of medical imaging procedures. However, the complexity of modern imaging equipment often surpasses the capabilities of standard dose calculation software, necessitating the use of commercially available dosimetry phantoms, which are often prohibitively …

The long and winding road of radiomics: learnings from two meta-analyses of the radiomics quality score

Nathaniel Barry, Jake Kendrick, Kaylee Molin, Suning Li et autres

The high-throughput extraction of radiomics features from medical images for predictive modelling holds great promise to improve the clinical management of patients. Previous meta-analyses into the radiomics quality score (RQS) applied in the literature have shown that after more than a decade …
