Summary: | To provide an ultrasonic probe which maintains electrical insulation between the inside and outside of a housing and reduces the size of an area of contact with a subject while maintaining the strength of at least an end of the housing.SOLUTION: An ultrasonic probe 1 has a housing 2 for housing an acoustic element module 4 including an array of transducer elements. The housing 2 includes a first housing 2A in which an acoustic lens 3 is disposed, and a second housing 2B. The first housing 2A comprises a first material having a Young's modulus of 40 GPa or more and also having electrical insulation. For example, the first material is a ceramic or metal having a Young's modulus of 40 GPa or more and also having electrical insulation.SELECTED DRAWING: Figure 1
【課題】筐体の少なくとも端部の強度を確保しながらも被検体との接触面の大きさを抑制し、なおかつ筐体の内部と外部の間の電気絶縁性を確保する超音波プローブを提供する。【解決手段】超音波プローブ1は、トランスデューサ素子のアレイを含む音響素子モジュール4を収容する筐体2を有する。筐体2は、音響レンズ3が設けられる第1の筐体2Aと、第2の筐体2Bを含む。第1の筐体2Aは、ヤング率が40GPa以上でありなおかつ電気絶縁性を有する第1の材料によって構成される。第1の材料は、例えばヤング率が40GPa以上でありなおかつ電気絶縁性を有するセラミックス又は金属である。【選択図】図1 |
