Material Evaluation of PC-ISO for Customized, 3D Printed, Gynecologic Ir HDR Brachytherapy Applicators
Purpose: To evaluate the radiation attenuation properties of PC-ISO, a bio-compatible, sterilizable 3D printing material and its suitability for customized gynecologic (GYN) brachytherapy 15 applicators. Method: A custom radiochromic film dosimetry apparatus was 3D-printed in PC-ISO. The apparatus contained a single catheter channel and a slit to hold a radiochromic segment. A brachytherapy dos...
متن کاملDosimetric characterization and output verification for conical brachytherapy surface applicators. Part II. High dose rate 192Ir sources.
PURPOSE Historically, treatment of malignant surface lesions has been achieved with linear accelerator based electron beams or superficial x-ray beams. Recent developments in the field of brachytherapy now allow for the treatment of surface lesions with specialized conical applicators placed directly on the lesion. Applicators are available for use with high dose rate (HDR)(192)Ir sources, as w...
متن کاملDosimetric evaluation of multilumen intracavitary balloon applicator rotation in high‐dose‐rate brachytherapy for breast cancer
The objective of this work is to evaluate dosimetric impact of multilumen balloon applicator rotation in high-dose-rate (HDR) brachytherapy for breast cancer. Highly asymmetrical dose distribution was generated for patients A and B, depending upon applicator proximity to skin and rib. Both skin and rib spacing was ≤ 0.7 cm for A; only rib spacing was ≤ 0.7 cm for B. Thirty-five rotation scenari...
متن کاملQualitative Dosimetric and Radiobiological Evaluation of High – Dose – Rate Interstitial brachytherapy Implants
Radiation quality indices (QI), tumor control probability (TCP), and normal tissue complication probability(NTCP) were evaluated for ideal single and double plane HDR interstitial implants. In the analysis, geometrically-optimized at volume (GOV) treatment plans were generated for different values of inter-source-spacing (ISS) within the catheter, inter-catheter-spacing (ICS), and inter-plane-s...
متن کاملCustom-made micro applicators for high-dose-rate brachytherapy treatment of chronic psoriasis
PURPOSE In this study, we present the treatment of the psoriatic nail beds of patients refractory to standard therapies using high-dose-rate (HDR) brachytherapy. The custom-made micro applicators (CMMA) were designed and constructed for radiation dose delivery to small curvy targets with complicated topology. The role of the HDR brachytherapy treatment was to stimulate the T cells for an increa...
