In contrast, an echogenic needle has an engraved pattern in the needle shaft that maximizes ultrasound wave reflection back toward the probe. Two types of echogenic etchings are in common use. The first type is a dihedral groove etched into the needle surface. This type of etching works well if the incoming wave is a plane wave aligned with the shaft of the needle. In most cases, the groove is etched continuously around the shaft of the needle similar to that of the thread on a screw. In this manner, the dihedral reflector actually becomes a universal three-dimensional surface reflector. The depth and period of the groove can be manufactured to optimize the reflection from sound waves of different frequencies. The other type of reflector is a tetrahedral reflector that has a four-sided intermittent etching in the shaft of the needle. In this case, the tetrahedral etching is the universal three-dimensional reflector, and the needle has a triangular pattern etched in its surface.
