I'm finaly starting RT & need some advice

In a bit of a dither, I’ve been waiting for RT to be arranged & started since 16/11/10.

Had a phonecall from hospital to arrange for me to go in on Saturday to have planning done using x-ray. Supposed to be with the new superduper simulator being installed (why more delay); but not going well & hospital having to make alternative arrangements.

Has anyone had their planning done with x-ray which has been mentioned in the BCC leaflet I have? I did think it would be using CT scan.

Is there any difference?
