Elscint Twin Flash Spiral CT

The Elscint Twin Flash Spiral CT was a dual-slice CT scanner built by the Israeli company Elscint in the 1990s. Such a system represented the advance in the timeline because it could acquire two slices of data per rotation, doubling the speed at which single-slice CT scanners could operate.

It used spiral (helical) scanning technology, enabling continuous data collection as the patient moved through the gantry, thus allowing faster and more detailed imaging.

Key benefits of the Twin Flash Spiral CT are its very short scan times, meaning that more patients will be processed without a decrease in diagnostic quality, especially when it comes to 3D reconstructions and angiographic studies. Thus, this will fit such purposes as brain aneurysm detection and vascular imaging, for which it is of crucial importance to get the minimum data in record time.

This was attributed to the dual-slice acquisition that the system employed, which extended the coverage area and reduced the scan times by roughly 50%. It thus became one of the more efficient scanners at that time.

The Twin Flash Spiral CT saw wide application in diagnostic imaging up until more modern multi-slice CTs were developed, capable of faster and higher-resolution images.
