摘要： A combined PET and X-Ray CT tomograph for acquiring CT and PET images sequentially in a single device, overcoming alignment problems due to internal organ movement, variations in scanner bed profile, and positioning of the patient for the scan. In order to achieve good signal-to-noise (SNR) for imaging any region of the body, an improvement to both the CT-based attenuation correction procedure and the uniformity of the noise structure in the PET emission scan is provided. The PET/CT scanner includes an X-ray CT and two arrays of PET detectors mounted on a single support within the same gantry, and rotate the support to acquire a full projection data set for both imaging modalities. The tomograph acquires functional and anatomical images which are accurately co-registered, without the use of external markers or internal landmarks.

摘要： The present invention provides an integrated, optimized process for the production of ethylene, carbon monoxide and acetic acid from an ethane feed, including reacting ethane with oxygen in the presence of a catalyst to produce ethylene, carbon monoxide and acetic acid in a reactor, wherein the catalyst comprises the elements Mo, Pd, X, and Y in the gram-atomic ratios MOa Pdb Xc Yd, and the oxygen partial pressure in the reactor is about 15 psia to about 50 psia. The partial pressure of ethane in the reactor is about 50 psia to about 150 psia.
