Abstract

A method includes the steps of measuring a surface profile of a first component, determining a profile of a second component, the profile of the second component being configured to correspond to the surface profile of the first component, and manufacturing the second component utilizing additive technology in accordance with the determined profile.

First claim

What is claimed is:

1. A method of manufacturing a lens for an ultrasound probe, comprising the steps of:
measuring a surface profile of an acoustic stack of the ultrasound probe;
calculating a profile for the lens;
printing the lens onto the acoustic stack in accordance with the calculated profile; and
wherein the step of calculating the profile for the lens includes calculating a curvature of the lens in dependence upon the measured surface profile of the acoustic stack.

2. The method according to claim 1 , wherein:
the acoustic stack includes an array of transducers.

3. The method according to claim 1 , further comprising the steps of:
aligning the probe within a 3D printer; and
constructing the lens by printing the lens having the calculated curvature.

4. The method according to claim 3 , further comprising the step of:
verifying the curvature of the lens after the lens is printed.

5. The method according to claim 4 , wherein:
measuring the surface profile of the acoustic stack is carried out utilizing a laser surface profilometer.

6. The method according to claim 5 , wherein:
the laser surface profilometer is configured to capture any variation of the acoustic stack in x, y and z planes and to detect any rotation around the x, y and z axes.

7. The method according to claim 1 , wherein:
the lens is comprised of a polymeric material.
