The most effective way to preserve high-frequency components of transmitted acoustic waveforms is by scanning through a water medium. This involves submerging the piezo element in a water bath and sweeping it in an arc, producing a high-quality trapezoidal image. Alternatively, a thin membrane can be used to create a contact scanning probe.

Moreover, the probe can operate with or without a sealed nosepiece. When the nosepiece is utilized, its opening is safeguarded by a transparent, thin membrane that allows for contact scanning through a short water pathway. Without the nosepiece, scanning takes place through an open water "bath," such as an eyecup or goggles, specifically for ophthalmic imaging.
