No carbs, no sweets. I’m Italian- I reside off of carbs! No bread, no pasta, no candy stuff, no juice… my eating regimen takes a hard beating before PET scans. You never want stuff until you possibly can’t have it- I REALLY wish to dive into these Milano cookies I’ve obtained in the cupboard, or eat a type of creamsicles within the freezer, or my triple chocolate dessert from Hanniford yesterday and never bought to eat, or the peach in my fridge… GRR!!

The fundamental principle behind a CT scan depends on the reconstruction of a 3 dimensional image of an organ, by a pc. During a CT scan, the affected person is moved along the scanning system, throughout which multiple X-ray photos of the organ being examined are acquired from different angles. These photos are obtained by passing a number of beams of X-rays by the area of interest. Sophisticated computer algorithms combine all these pictures to create a view of the organ, which is offered soon after the scan is full.

Kolimator yang umum digunakan pada pesawat SPECT adalah kolimator parallel-gap. Namun telah diciptakan pula berbagai kolimator khusus. Sebagai contoh, fan beam kolimator yang merupakan hibrida dari kolimator konvergen dan paralel. Setiap baris piksel pada paralel kolimator arah y sesuai dengan satu slice citra proyeksi. Dengan kolimator konvergen, citra hasil citra akan mempunyai resolusi spasial lebih tinggi dibanding dengan arah kolimator parale-gap.
