Image advantages

It is important to keep in mind that hydrophilic prosthetic groups are important for renal rather than hepatobiliary clearance. Wester et al. [62] have demonstrated this with their carbohydrated analogs. Since 18F possesses inherent imaging advantages, the development of a simple and rapid synthesis which will enable 18F-SSTr ligands to be clinically practical is also important. 

Real Time Radiography (RTR) is an advanced method of radiography in which the image is formed while the job is exposed to ionising radiation. RTR is often applied to objects on assembly lines for rapid inspection. Accept-or-reject decisions may be made immediately without the delay or expense of film development. The main advantages of RTR are thus, reduction in inspection cost and processing time. 

The lead time for making a image by film X-Ray is 10 to 15 minutes. Where about 2 minute are needed in inspection by Real-Time X-Ray. Another advantage of Real-Time X-Ray is the feature that the effect of manipulating the part or changing the setting of the X-Ray tube can be observed directly. This is often used in investigating quality problems. 

An advantage of Real Time X-Ray is that since only one section of the part is inspected at the time the X-Ray parameter settings can be optimised per section. At the same time each section is irradiated almost perpendicular which gives less distortion in the image of the top and the bottom section of blades. 

The specific advantage of this technique is its higher sensitivity than classical film radiography and the potential for automated image processing due to the digital read-out of the IP s. Former investigations have shown / / that the available IP s achieve the same contrast like NDT films with an IP type and scanner dependent unsharpness.
