A team of scientists are now making it safer, faster, and easier for doctors to make use of an emerging procedure, one that is involved with the burning away of tumors in more patients, comprising those with brain tumors.
Around 80,000 Americans are expected to be diagnosed with a brain tumor this year in accordance with the American Brain Tumor Association. A good many of them would need chemotherapy and major surgery. Around sixteen thousand of them would loose the battle. However, a team of USC Viterbi School of Engineering researchers are now making it safer, faster, and easier for doctors to make use of an emerging procedure, one that comprises burning away tumors in more patients, including those with brain tumors.
Tumors Tissues are Burned Till Gets Destroyed
Radiofrequency ablation, or RFA, refers to a minimally invasive procedure that makes use of electrical energy so as to destroy cancer cells with heat. A needle-thin probe makes a delivery of radio frequency waves directly to the tumor thereby cooking the tissue up to around 140 degrees Fahrenheit i.e. around 60 degrees Celsius, until it gets destroyed.
Assistant professor John Stang of the Ming Hsieh Department of Electrical Engineering, who co-authored the study said that although ablation is becoming increasingly gaining traction and there is still no thermal imaging technology for regular clinical use so as to monitor these procedures in real time and ensure that the correct thermal dose is delivered at the very first time.
Together with Mahta Moghaddam, director of the Microwave Systems, Sensors, and Imaging Lab, or MiXIL, and holder of the William M. Hogue Professorship in Electrical Engineering at USC, Stang has come up with a real time thermal imaging method and device that would assist doctors in fast and precise delivery of thermal ablation treatments for a wide variety of ailments ranging from epilepsy to tumors.
The study has been published on IEEE Transactions on Biomedical Engineering.
