Mobile CT
 

The picture at the bottom shows a mobile CT system (Philips Tomoscan M) that is used in National Neuroscience Institute (NNI). The Tomoscan M mobile CT system is manufactured for Philips Medical Systems by Analogic Corp. (Peabody MA, U.S.A). The system has three main components, all of which are mounted on wheels: a compact CT gantry, a CT table that docks with the gantry, and an operator's console. The gantry tilts +30° and -25°, and has the unique ability to translate in the horizontal axis by up to 35 cm, allowing head, neck and face to be scanned without having to transfer the patient to the CT table.

The system power is provided by four 48volt batteries that can be charged from any standard 240V outlet. One main disadvantage is that the overall scan time is much longer than a conventional CT. Increased overall scan time was primarily due to a slower cycle time because of low mA supplied and the need for tube cooling.  

The mobile CT in NNI is used mainly for Neuro and spinal surgery. One particular example is to check for delayed intracranial haemorrahages to reduce potential risk. Delayed intracranial haemorrhages may occur as a result of the release of tamponade that occurs after operative evacuation of intracranial haematomas. Normally, such delayed bleeds are not recognized until the patient is scanned in the fixed unit, which may be several hours later. The ability to return the patient to the OT table immediately within the same operative setting without having to open new sterile packs or expend personnel time on 're-prepping' the OT, also potentially decreases overall treatment costs.
