Development and Analysis of Coaxial Slot Antenna in Comparision with Coaxial Dipole Antenna for Interstitial Microwave Ablation
Hepatocellular carcinoma (HCC) is the most common malignant tumors to affect the liver. Microwave ablation is efficiently used for treatment of liver cancer. Although surgical resection remains the gold standard for treatment of liver cancer, but only 5-10% patients are the candidates for surgical resection due to numbers of limitations. Because most patients with HCC can not be treated with su...
متن کاملThe Effect of Choke on the Efficiency of Coaxial Antenna for Percutaneous Microwave Coagulation Therapy for Hepatic Tumor
There are many perceived advantages of microwave ablation have driven researchers to develop innovative antennas to effectively treat deep-seated, non-resectable hepatic tumors. In this paper a coaxial antenna with a miniaturized sleeve choke has been discussed for microwave interstitial ablation therapy, in order to reduce backward heating effects irrespective of the insertion depth into the t...
متن کاملStudy on Interstitial Microwave Hyperthermia with Multi-slot Coaxial Antenna
This study focuses attention on interstitial microwave hyperthermia, which is a popular medical procedure for treatment of pathological human tissues containing tumors. In the paper, the 2D finite element analysis is used to compare the models of the coaxial antenna with one, two and three air slots. The implemented models are based on the wave equation in the TM mode coupled with the Pennes eq...
متن کاملMicrowave Tumor Ablation of Vertebral Bone Metastasis: A Case Report
Introduction: Thermal ablation by microwave (MWA) has proven efficacy in treatment of primary and metastatic cancers. Soft tissue tumors could be ablated completely using MWA. However, bony tissue metastasis particularly spinal vertebral metastasis ablation has not reported yet. Case presentation: A 50 year old male patient with primary diagnosed colon cancer undergone surgical resection of ...
متن کاملA review of coaxial-based interstitial antennas for hepatic microwave ablation.
Although surgical resection remains the gold standard for treatment of liver cancer, there is a growing need for alternative therapies. Microwave ablation (MWA) is an experimental procedure that has shown great promise for the treatment of unresectable tumors and exhibits many advantages over other alternatives to resection, such as radiofrequency ablation and cryoablation. However, the antenna...
