Non destructive testing (NDT) covers a wide group of techniques used to evaluate the properties of a material, part, product, weld, or system without materially affecting the integrity of the unit being inspected or investigated under the test procedure. ... Element offers computed tomography with high-resolution 3D images to provide detailed ...

Temporal resolution is the ability to detect that an object has moved over time. For the purposes of medical ultrasound, temporal resolution is synonymous with frame rate. Typical frame rates in echo imaging systems are 30-100 Hz. The temporal resolution or frame rate = 1/(time to scan 1 frame). The time to scan one frame is equal to the pulse ...

The essential parts of any NDT method are 1) application of a probing or inspection medium, 2) modification of the probing or inspection medium by defects or variations in the structure or properties of the material, 3) detection of this change by suitable detector or sensor, 4) conversion of this change into a suitable signal or image and 5) interpretation of the information obtained [2].

Dec 29, 2011 · The primary objective of any NDT test is to increase product reliability by finding discontinuities when they are small, before they become big enough to cause costly repairs or a component failure. A component failure could cause an entire system to be shutdown or create a safety hazard that could lead to personal injury.

NDT technology, codes and compliance rules, are changing and that is where knowledge of new technology and Industry code requirements is a necessity. We offer both advanced NDT and conventional NDT methods. Clients need to have access to the quality NDT services but also the reassurance that their NDT provider is highly skilled in the method used.

Full matrix capture (FMC) is a specific data-acquisition process using ultrasonic phased-array probes. For an array of N elements, each element is successively used as the transmitter, while all other elements are used a receivers. The animation illustrates the sequencing of the shots fired by a phased-array probe used for FMC (orange = transmitting element, blue = receiving elements).
