Revolution Of CT Scanners....

FIRST GENERATION CT SCANNER

This type of CT generation uses pencil beam.

It is a Translate-Rotate Design with the used of 180 one degree images or translations. 

It also utilizes one or two detectors.

That's why it takes about 5 minutes per scan time.

SECOND GENERATION CT SCANNER

Just like the 1st generation, this 2nd generation CT Scanner was also designed asTranslate-Rotate.

The differences from the 1st generation are : 

1) it applies fan beam collimation so there is more scatter radiation.

2) it uses 5 to 30 detectors.

3)10 degrees /translation 18 per scan, which is about 30 second scan times.

4) it is faster scan time if compared to 1st generation CT scan.
