What does "volume coverage" mean?
Barion: "Volume coverage" means that the CT has a wide detector. Canon Medical Systems offers in the Aquilion ONE Genesis platform the most innovative detector with 640 layers and 0.5 millimeter detector elements over 16 cm. This makes it possible to detect a relatively large volume, such as entire organs, within a single rotation. The examination time of a cardiac CTA, for example, only takes 138 milliseconds.
A large coverage is also an enormous advantage in neuroimaging. The examination time to exclude a stroke-induced infarct with extensive bleeding up to subarachnoid hemorrhage or ruptured aneurysms is possible within 275 milliseconds.
What is the challenge for doctors in evaluating the images?
Barion: Thanks to modern high-performance post-processing consoles, the radiologists have access to all the results of the perfusion cards, including penumbra, in just two minutes.
In addition, the 4D-CTA of the head vessels is also displayed isophasically, allowing the user to get an exact picture of the physiological processes in the patient's head, similar to the DSA. This enables a clear and dynamic overview of the brain-supplying arteries and thus shortens the time required for therapy planning or execution.
