Immobilization and image-guidance methods for radiation therapy of limb extremity soft tissue sarcomas: Results of a multi-institutional survey

Autor: Rob H. Ireland, James A. Swinscoe, Colleen Dickie

Publikováno v: Medical Dosimetry. 43:377-382

Radiation therapy for limb-extremity soft tissue sarcoma (STS) requires accurate, reproducible dose delivery. However, patient positioning is challenging and there is a lack of existing guidelines to assist institutional standardization. Therefore, w

Ventilation CT: Voxel-level comparison with HP gas MRI

Autor: Felix Horn, Jim M. Wild, Guilhem Collier, Neil J. Stewart, Matthew Q. Hatton, Graham Norquay, James A. Swinscoe, Paul Hughes, Helen Marshall, Kerry Hart, Rob H. Ireland, Bilal A Tahir

Publikováno v: 1.3 Imaging.

Introduction: Image registration of inspiratory & expiratory CT is a potential method of mapping regional ventilation assuming lung expansion & density changes of corresponding parenchymal voxels equates to ventilation. However, its physiological acc
