Abstract
Examples of the present subject matter provide techniques to accurately size flaws using acoustic inspection without expending significant computing resources and time. Examples described herein include techniques to convert amplitude-based inspection images, such as TFM or phased array ultrasonic testing (PAUT) images, into sizing images based on Acoustic Influence Maps (AIMs).
Claims21
A method comprising:
- receiving acoustic echo data comprising time-series representations of acoustic echo signals from insonifying a structure in an object;
- obtaining one or more Amplitude Influence Maps (AIMs) corresponding to a structure type of the structure from a pre-generated database;
- based on the one or more AIMs, converting amplitude values in the received acoustic echo data into one or more corresponding size values, wherein the size values are diameter size of the structure;
- and
- generating an image having voxels representing the size values of the structure as colors based on the converted size values.

A machine-storage medium embodying instructions that, when executed by a machine, cause the machine to perform operations comprising:
- receiving acoustic echo data comprising time-series representations of acoustic echo signals from insonifying a structure in an object;
- obtaining one or more Amplitude Influence Maps (AIMs) corresponding to a structure type of the structure from a pre-generated database;
- based on the one or more AIMs, converting amplitude values in the received acoustic echo data into one or more corresponding size values, wherein the size values are diameter size of the structure;
- and
- generating an image having voxels representing the size values of the structure as colors based on the converted size values.
2 more elements
A system comprising:
- one or more processors of a machine;
- and
- a memory storing instructions that, when executed by the one or more processors, cause the machine to perform operations comprising:
- receiving acoustic echo data comprising time-series representations of acoustic echo signals from insonifying a structure in an object;
- obtaining one or more Amplitude Influence Maps (AIMs) corresponding to a structure type of the structure from a pre-generated database;
- based on the one or more AIMs, converting amplitude values in the received acoustic echo data into one or more corresponding size values, wherein the size values are diameter size of the structure;
- and
- generating an image having voxels representing the size values of the structure as colors based on the converted size values.
