Abstract
A system for determining a borehole shape may comprise a measurement assembly, wherein the measurement assembly may comprise a housing with an outer surface, a transducer disposed flush along the outer surface of the housing, and an extruded boss that connects to the outer surface of the housing. A method may comprise disposing a downhole tool that includes an instrument section into a wellbore and transmitting an excitation from the transducer into the wellbore, wherein the excitation is reflected off a wellbore wall as an echo.
