摘要： During hyperthermia treatment of the head and neck area a conventional water bolus, used in such treatment for guiding electromagnetic waves and cooling the patient's skin, may collapse onto the patients face due to the weight and/or pressure of the water inside the water bolus. An insert may be provided inside the water bolus to remedy this, wherein the insert provides additional stiffness and thus resistance against the water's weight and pressure. The insert however should not be too resistant against the shape of the patient, and thus an insert is provided with a first stiffness in a first load direction and a second stiffness in a second load direction, wherein the first stiffness is not equal to the second stiffness.

摘要： According to one aspect, an interstitial hyperthermia device has an electrode structure to be coupled to an electric power source for providing an alternating electric field for heating up a patients tissue. The device is provided with a hollow source guide for conducting a radiation source capsule to be moved by a guidewire. The hollow source guide has an inner wall for guiding the source capsule and an outer wall to be contacted with the patients tissue. The outer wall is provided with the electrode structure arranged on a circumference of the outer wall of the hollow source guide and having a dielectric layer shielding the electrode structure from the patients tissue.
