Factors Affecting Tumor Ablation during High Intensity Focused Ultrasound Treatment

BACKGROUND/AIMS High intensity focused ultrasound (HIFU) utilizes a targeted extracorporeal focused ultrasound beam to ablate neoplastic pancreatic tissue. We used an in vitro model to examine the effects of bone, metallic stents, plastic stents, metal plates, and cyst-like lesions on HIFU treatment. METHODS HIFU was delivered to the phantom models implanted with foreign bodies, and the locat...

Numerical Study for Optimizing Parameters of High-Intensity Focused Ultrasound-Induced Thermal Field during Liver Tumor Ablation: HIFU Simulator

Introduction High intensity focused ultrasound (HIFU) is considered a noninvasive and effective technique for tumor ablation. Frequency and acoustic power are the most effective parameters for temperature distribution and the extent of tissue damage. The aim of this study was to optimize the operating transducer parameters such as frequency and input power in order to acquire suitable temperatu...

Fast algorithm in estimating high intensity focused ultrasound induced lesions

High Intensity Focused Ultrasound (HIFU) has been emerging as a new and effective modality in non-invasive thermal ablation for cancers and solid tumours. Although a theoretical model is available for calculating thermal field and the consequent lesion production, its computation is too time-consuming (~ 1 day) for HIFU treatment planning on the site. In this study, several approximations were ...

High intensity focused ultrasound (HIFU).

INTRODUCTION Curative treatments for localized prostate cancer, from least invasive to most invasive, include brachytherapy, cryosurgery, three-dimensional conformal radiation therapy, external beam radiation therapy, and radical prostatectomy. A patient with localized, low risk or intermediate risk prostate cancer who is diagnosed at an early age and receives one of these treatments has only a...
