Brightview XCT

[Mike A]

Has anyone yet had one of these installed?

If you want to do myocardial perfusion with attenuation correction, how much extra time does the AC take in practice? From a picture it looks like the heads wiill have to reconfigure to do the AC part since, in L mode, they obscure the flat panel xray detector. Right?

Asking other colleagues, I reckon Symbia T2 takes extra 20sec, T6 takes 10sec, GeHawkeye 4 takes 20s. Do these figures sound right?

I am the Product Manager for the Philips BrightView XCT. The SPECT detectors do not need to be reconfigured when performing a Relative-90 (L-mode) cardiac SPECT acquisition with attenuation correction. The SPECT detectors remain in the Rel-90 position during both the CT-AC acquisition and the SPECT acquisition. There is sufficient space between the Rel-90 SPECT detectors for the x-ray beam to reach the flat panel detector. When performing a localization study, the SPECT detectors remain in the Rel-180 position during both the CT and SPECT acquisitions. There is no detector angle reconfiguration needed between the CT and SPECT acquisitions within the SPECT/CT protocol.

Jody,

Thanks for your reply, it's very helpful. Ive now received from our local supplier some clinical images, it looks good.

I'm a french medical physicist and I need some information on SPECT-CT present and future solutions to prepare a presentation on this topic during a post-graduate teaching course. It would be very kind if you could help me in anyway. Thanks in advance. Olivier CASELLES, caselles.olivier@claudiusregau d.fr
