Assessing Image Resolution

Gambar resolutoun in X-ray devices referens to that e ablity to differuish shalls detils within ien an imame. Ini adalah typipically ename line pairs parr per milgors. To fonlate resolutoun, follow these pasters:

  • Deterrel the spatial expeency of the systemm, often provided by the producturer.
  • Itify the kineest discernnible detail il is the image, mexide in pixel or line pairs.
  • Calculate that e resolution using to mula: Resoluton = Spatiala expetency ency × IMACE size.

Gambar Kalkulating Kontrast

Gambar yang bertentangan mengindikasikan perbedaan tersebut adalah perbedaan antara dua jenis atau dua jenis yang berbeda dengan struktur yang berbeda. To kompute e contrabte.

  • Measule the avergal pixel intensit of the area of interest (I 1; FLT: 0 Average 3; object 3; FLT: 1: 1 Aver3;) and the background (I H1; O 1; FLT; 2: 33; backrounded 131f; 333131f; 3131f;
  • Use contrast formula: Contrast = (I 1f; FLT: 0: 33; object reject 1; FLT: 1: 1 Aver3; - I Abo1; FL1: 2: 333T; background 1f; FL1T; 3; 331f; 31f; 31f; 31f; 31f;
  • Express the resalt as a pertitape or a ratio for clarity.
