On EM Reconstruction of a Multi Channel Shielded Applicator for Cervical Cancer Brachytherapy: A Feasibility Study [PDF]

Med. Phys., (2018) 45: 1673-1676, 2017
Electromagnetic tracking (EMT) is a promising technology for automated catheter and applicator reconstruc- 10 tions in brachytherapy. In this work, a proof-of-concept is presented for reconstruction of the individual channels of a shielded tandem applicator dedicated to intensity modulated brachytherapy.

A Brief Review of Low-Dose Rate (LDR) and High-Dose Rate (HDR) Brachytherapy Boost for High-Risk Prostate [PDF]

Frontiers in Oncology, 2019
For patients with unfavorable or high-risk prostate cancer, dose escalated radiation therapy leads to improved progression free survival but attempts to deliver increased dose by external beam radiation therapy (EBRT) alone can be limited by late ...

A GPU-based multi-criteria optimization algorithm for HDR brachytherapy [PDF]

, 2019
Currently in HDR brachytherapy planning, a manual fine-tuning of an objective function is necessary to obtain case-specific valid plans. This study intends to facilitate this process by proposing a patient-specific inverse planning algorithm for HDR prostate brachytherapy: GPU-based multi-criteria optimization (gMCO).

Optimization of a multipoint plastic scintillator dosimeter for high dose rate brachytherapy [PDF]

, 2018
Purpose: This study aims to optimize and characterize the response of a mPSD for in vivo dosimetry in HDR brachytherapy. Methods: An exhaustive analysis was carried out in order to obtain an optimized mPSD design that maximize the scintillation light collection produced by the interaction of ionizing photons.

MRI/TRUS data fusion for brachytherapy [PDF]

International Journal of Medical Robotics and Computer Assisted Surgery 2, 3 (2006) 256-61, 2007
BACKGROUND: Prostate brachytherapy consists in placing radioactive seeds for tumour destruction under transrectal ultrasound imaging (TRUS) control. It requires prostate delineation from the images for dose planning. Because ultrasound imaging is patient- and operator-dependent, we have proposed to fuse MRI data to TRUS data to make image processing ...

Structurally Defined Water‐Soluble Metallofullerene Derivatives towards Biomedical Applications

Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
A modular metallobuckytrio (MBT) platform provides a family of structurally defined, water‐soluble metallofullerene derivatives that can safely carry rare‐earth elements in tailorable molecules, showing promise in biomedicines including MRI contrast agents and photosensitizers. Abstract Endohedral metallofullerenes (EMFs) are excellent carriers of rare‐

Superficial radiation therapy for nonmelanoma skin cancer: A review

Dermatological Reviews, Volume 3, Issue 6, Page 409-417, December 2022., 2022
Abstract Background The high prevalence of nonmelanoma skin cancer (NMSC) has become a global health‐care burden. Various modalities have been established to treat NMSC, with surgery being the mainstay approach. Superficial radiation therapy (SRT) has been in use for over a century to treat various conditions. Recent discussion among the dermatological
