PET- imaging without CT.

CT-free PET reduces radiation dose.

In PET imaging, CT should be used for attenuation correction and localization.

Low-dose CT increases the patient's dose. Attenuation map misregistration frequently happens in PET-CT imaging.





A new revolution is coming soon in the nuclear imaging world. The lutetium crystal contains 3 % of Lu-176 which can be used to create an attenuation map of the patient. Lu-176 emits 202 and 307 keV gamma photons.

Lu-176 can be used to scan the patient for attenuation correction. This revolution would reduce the patient dose, eliminate the misregistration map attenuation, and can be used for PET-MRI attenuation correction procedures.

السلام عليكم الناهرده هاتكمل عن اذاى تخبر ال   Dose calibrator  فى المعمل وتتاكد من كفائته وده هايتم عن طريق الاختبارات التاليه :- 1.       Accuracy at installation :- 2.       Constancy daily test 3.       Linearity 4.       Geometry at installation Accuracy at installation 1-      انا عايز اتاكدان ال dose calibrator قرائته سليمه فبالتالى محتاج مصدر معلوم القوه الاشعاعيه مثل ( (57Co, 133Ba and 137Cs ويكون له long half live  وابتدى احسب القوه الاشعاعيه للمصدر فى تاريخ القياس بمعلومية نشاطه الاشعاعى فى تاريخ سابق يبقى انا كده عندى ال original activity( A0) ومحتاج احسب النشاط الاشعاعى عند زمن القياس A(t) وممكن تستخدم المعادلات التاليه :- A(t)=A(0)/2*n n = (no of days left from the activity measurment day) /T 1/2 2-      يمك...

 • Fourier transformation • French mathematician Joseph Fourier discovered the Greenhouse effect. He explained how combining a variety of various-sized sine waves might result in any sort of wave imaginable. This is important for our needs since we may employ certain sine waves (produced by analog devices) to generate digital readouts. • Fourier analysis: Identifying the sine waves that make up a specific signal (think of it as reverse engineering soup - identifying all the ingredients, types, and amounts from a sample of the finished soup). • Fourier transform The process of converting from the frequency domain to the spatial domain (distance or time) or vice versa. The spatial domain contains all of the sine waves, but the frequency domain has only one. • Aliasing Aliasing is a 'undersampling' problem. It is the phrase used to describe the visual confusion that occurs when a real thing is seen erroneously. A real-life example would be watching a spinning wheel (or the rotor b...
