In vivo mEHT instrument. (a) The mouse was sedated and fixed on the mEHT instrument. The optical sensors were used to detect the temperature within the various body sites. The T1 sensor inserted into the tumor; T2 sensor inserted into the subcutaneous site; T3 sensor inserted within the rectum. (b) The upper electrode was covered on the tumor, which was on the wet pad to prevent from overheated. (c) The measured temperature curves of T1 ~ T3, T4: room temperature
