==Graphical representations of ultrasound images==

Imaging ultrasound testing basically covers all graphical representations of amplitude as a function of time or location. It ranges from simple [[HF-Scan|HF-scan]] representation using a simple oscilloscope to [[A-Scan Technique|A-scan]] and 4d-scan. The information provided by ultrasonic images varies depending on the type of representation. The A-scan (rather than the HF-scan) is particularly important due to its relatively easy-to-interpret representation. For this reason, it is not customary to classify this representation of ultrasonic signals, which has existed since the early days of [[Ultrasound Testing|ultrasound testing]], as imaging ultrasound testing. In addition, for physical reasons, [[Ultrasound Testing|ultrasound testing]] is mostly used as a single-point test, whose signals are processed as HF- or A-scans. It was only later that line scanning ([[B-Scan Technique|B-scan]]) and area scanning ([[C-Scan Technique|C]]/[[D-Scan Technique|D]]-scan) became technically viable. The scan is actually a raster scan, because the A-scans are composed as images in line or area form and scaled (by colour or grey scale) ('''Fig. 1'''). To ensure that the sensor is subject to as little mechanical wear as possible, the scans are performed using, for example, the [[Squirter Technique|squirter technique]] or [[Ultrasonic Immersion Bath Technique|immersion technique]]. The basic metrological requirement is therefore an active scanning process of the [[Ultrasonic Sensors|ultrasonic sensor]] or the ultrasonic beam in [[Ultrasonic Phased Array Sensors|phased array technology]], as well as passive scanning, in which the test piece moves under an ultrasonic test field. With this type of measurement, the [[HF-Scan|HF-signals]] are recorded as a function of location and time and evaluated in terms of signal propagation time and/or amplitude or attenuation.

==Types of imaging in ultrasonic testing==

The actual ‘ultrasonic imaging test’ is therefore characterised by the graphical 2D or 3D representation of the ultrasonic signal. A distinction is made between

* [[HF-Scan|HF-scan]],
* [[A-Scan Technique|A-scan]],
* [[B-Scan Technique|B-scan]],
* [[C-Scan Technique|C-scan]],
* [[D-Scan Technique|D-scan]] and
* [[F-Scan Technique|F-scan]]

as well as several other types of representation that have been developed for special cases.
