In this test, the doctor inserts an ultrasound probe into the throat after the patient is sedated. 被測者首先需要被施用一定的鎮靜劑，然后醫生將一個(gè)超聲波探頭通過(guò)被測者的喉嚨穿入到食道進(jìn)行檢測。
In a newer method, an ultrasonic probe enters the cut in the cornea and high-speed vibrations break the lens into microscopic flecks that are then removed by suction. 有一種更先進(jìn)的方法，把超聲波探頭伸到角膜切口內，高速的振動(dòng)將晶狀體變成微小的碎片，然后吸出這些碎片。
These often rely on the ultrasonic probe being connected to a manually operated scanning arm with the position being encoded. 這些通常根據由手動(dòng)操作的掃描桿連接的超聲波探針和譯碼器確定的位置來(lái)繪制。
