| Popis: | This is an initial demonstration of volumetric cine imaging under free breathing in lung cancer patients using the second model of the 256-detector row CT (256MDCT). Scan range is 128 mm in the cranio-caudal direction with a 0.5 mm slice thickness and effective temporal resolution of 250 ms. Volumetric cine images are satisfactorily obtained for the thin sections which can be used to create cine loops in multiple planes. Thus, the 256MDCT overcomes some of the limitations of current respiratory-gated CT or 4D-CT scan techniques and has the potential for use in 4D-IMRT planning and 4D radiation therapy. |
