The present study aimed to compare the risk of a secondary cancer from scattered and leakage doses in patients receiving intensity-modulated radiotherapy (IMRT), volumetric modulated arc therapy (VMAT), and stereotactic radiosurgery (SRS). Four acoustic neuroma patients were treated with IMRT, VMAT, or SRS. Their excess relative risk (ERR), excess absolute risk (EAR), and lifetime attributable risk...
Several types of implantable middle ear hearing devices (IMEHDs) have been developed to overcome disadvantages of the conventional hearing aids. IMEHDs are divided into three parts which are a microphone, a signal processing unit, and a vibration transducer. In particular, the vibration transducer is very important component because it directly generates the mechanical vibration in the ossicles so...
We announced that fully implantable middle ear hearing device (F-IMEHD) has been researched in several papers. The F-IMEHD requires proper fitting process reflected properties of each device like other hearing aids. The F-IMEHD uses vibration transducer attached on ossicles for a sound transmission to human's inner ear. The F-IMEHD is implanted under the skin. Therefore, the fitting process for F-IMEHD...
