The Temperature Rise of Small Metal Piece Buried in Agar Irradiation by Ultrasound
Irradiation of ultrasound to a tissue where a metal is buried results in a specifically abnormal increase in temperature of the tissue. However, the increase is small, and there is no contraindication to the irradiation of ultrasound to the tissue. In the present study, a small piece of metal, which...

| Summary: | Irradiation of ultrasound to a tissue where a metal is buried results in a specifically abnormal increase in temperature of the tissue. However, the increase is small, and there is no contraindication to the irradiation of ultrasound to the tissue. In the present study, a small piece of metal, which is unaffected by constant wave, reciprocating wave and heat conduction, was buried in an agar to the depth of 3 cm from the surface. The agar was irradiated by ultrasound for 2 min, and the temperatures of the metal and of agar around the metal were measured 4 min after the start of irradiation. It was confirmed that there was an increase in temperature around the border between a metal and agar. |
