Spectral Precise Image is a reconstruction technique where the system uses a trained deep learning neural network to produce an image that reduces noise while improving low contrast detectability and maintaining the appearance of traditional filtered back projection (FBP) images.
Spectral Precise Image in Spectral CT 7700 system supports both conventional and spectral reconstructions.
The study will use raw data of subjects that are over the age of 22 years and scanned by Philips Spectral CT.
Study raw data, following anonymization, will be transferred to Philips for reconstructions, both conventional and spectral images will be reconstructed with iDose4 and with Spectral Precise Image at 100% dose.
