A novel conformal superficial high-dose-rate brachytherapy device for the treatment of nonmelanoma skin cancer and keloids  Clara Ferreira, Daniel Johnson, Karl Rasmussen, Clinton Leinweber, Salahuddin Ahmad, Jae Won Jung  Brachytherapy  Volume 16, Issue 1, Pages (January 2017) DOI: /j.brachy Copyright © 2016 American Brachytherapy Society Terms and Conditions

2 Fig. 1 Conformal superficial brachytherapy (CSBT) device showing possible seed expansions for positioning in the skin surface to conform to treatment lesion. Time and position of each seed can be controlled to optimize the treatment. Brachytherapy  , DOI: ( /j.brachy ) Copyright © 2016 American Brachytherapy Society Terms and Conditions

3 Fig. 2 (a) Clockwise direction, starting from top left: frontal view of the template with no rods extended, field 1 (yellow), superposition of fields 1 and 2 (orange), superposition of fields 1, 2, and 3 (red). (b) Representation of total dose distribution from all fields added. “(For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)” Brachytherapy  , DOI: ( /j.brachy ) Copyright © 2016 American Brachytherapy Society Terms and Conditions

8 Fig. 7 MCNPX 2.6% depth dose and radial simulations for the dose per decay profile of model used for experimental setup using the 142Pr glass rod. The dose falloff is steep and drops to minimal values at points beyond 5 mm. Brachytherapy  , DOI: ( /j.brachy ) Copyright © 2016 American Brachytherapy Society Terms and Conditions
