FDTD analysis of a noninvasive hyperthermia system for brain tumors
BACKGROUND Hyperthermia is considered one of the new therapeutic modalities for cancer treatment and is based on the difference in thermal sensitivity between healthy tissues and tumors. During hyperthermia treatment, the temperature of the tumor is raised to 40-45°C for a definite period resulting in the destruction of cancer cells. This paper investigates design, modeling and simulation of a ...
متن کاملCT-guided laser probe for ablation of brain tumors
In this study, 22 patients (15-75 years old) were selected and transferred to CT scan for tumor ablation. For ablations, after prep and drep under the local anesthesia and mild sedation in proper position, small incision made and special needle inserted and guided by proper direction to the core of the tumor. Then, laser probe inserted through the needle and laser energy delivered. Although we ...
متن کاملHyperthermia and the therapy of malignant tumors.
A solution to get the problem off, have you found it? Really? What kind of solution do you resolve the problem? From what sources? Well, there are so many questions that we utter every day. No matter how you will get the solution, it will mean better. You can take the reference from some books. And the hyperthermia and the therapy of malignant tumors is one book that we really recommend you to ...
متن کاملTheoretical study of convergent ultrasound hyperthermia for treating bone tumors.
This study investigates the optimal external parameters for using an ultrasound applicator for treating bone tumors. This system utilized spherically arranged applicators such as scanned focused ultrasound, and spherically focused multielement applicators. The power deposition pattern is modeled as geometric gain with exponential attenuation. The specific absorption rate ratio (SARR) criteria h...
متن کاملRandomized trial of hyperthermia and radiation for superficial tumors.
PURPOSE Randomized clinical trials have demonstrated hyperthermia (HT) enhances radiation response. These trials, however, generally lacked rigorous thermal dose prescription and administration. We report the final results of a prospective randomized trial of superficial tumors (</= 3 cm depth) comparing radiotherapy versus HT combined with radiotherapy, using the parameter describing the numbe...
