In this paper, we discuss a new method of controlling heating location in the proposed resonant cavity applicator. A dielectric bolus was used to non-invasively treat brain tumors. We have already confirmed that our heating system using resonant cavity is useful to non-invasively heat brain tumors. In order to heat tumors occurring at various locations, it(More)
The positron camera system was designed and developed at the secondary beam course of HIMAC to measure heavy-ion ranges in bodies of patients. By using the pencil-like beam of positron emitters, such as C, the range is checked directly and precisely by detecting pairs of annihilation gamma rays emitted from the stopping point of the beam. The positron(More)
In this study, we propose a new heating method using a resonant cavity applicator to control the heated area using a dielectric bolus. The dielectric bolus is filled with a dielectric material such as water and is attached to a human head inside the cavity. In this paper, first, the proposed heating method using the dielectric bolus was described. Second, a(More)
This paper discusses the improvements of the re-entrant resonant cavity applicator, such as an electromagnetic shield and a water bolus for concentrating heating energy on deep tumors in an abdominal region of the human body. From our previous study, it was found that the proposed heating system using the resonant cavity applicator, was effective for(More)
This paper describes a heating control method of the resonant cavity applicator for brain tumor hyperthermia treatment. In this study, we proposed several heating control method. In the first method, the diameters of the inner electrodes are changed. In addition, the position of the phantom between the inner electrodes was changed. In the second method, the(More)
