Once we have discussed the object to be scanned with you in detail, we will have a dedicated slot reserved for CT scanning your item at our CT scanning facility.
Each scan is supervised by our Consultant Radiologist, Dr Andrew Gogbashian.
The object will carefully be placed on the CT scanner table and re-measured to ensure it physically fits within the scanner ‘ring’. The scanner ‘ring’ is extremely wide with a diameter of 78cm which is able to accommodate most objects. Generally the length of the object is not an issue.
Once the item is satisfactorily placed on the table, the object is imaged remotely from the adjoining control room with several ‘scout images’ taken to ensure an adequate position and view of the object.
After these initial ‘scout views’ full CT scan images are then obtained.
We use multiple scan parameters and perform ‘on-the-fly’ image reconstructions in 2D and 3D in order to ensure we have obtained the best CT scan images possible for your item.
Sometimes if the object is very large, we may have to obtain 2 sets of images to cover the entire item. Generally, if the width of an object is 50cm or less, the entire object may be scanned in one image.
The images are sent to specialist workstations for further analysis.
Depending on the circumstances and complexity of the scenario, the entire process can take a few hours.
Dr Andrew Gogbashian will analyse your images and reconstruct them in 2D and 3D. Usually a separate second meeting is useful to discuss these final images.
All the data that is acquired is provided to you on CD, USB stick or hard disk.
