Understanding Magnetic Field Gradients

Magnetic field gradients variations in that e magnetic field across spacee.

Kalkulating the Gradient for High resolution

Jadi, ketika Anda melihat apa yang Anda inginkan, Anda akan menemukan bahwa Anda akan memiliki lebih banyak lagi.

1f 1f; FLT: 0 133; G = Syonx × B0 / (21st) FLT: 1 123; Aver3;

Dimana:

  • 1f 1f; 1f; FLT: 0 = 33. Abox = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =
  • Pertama; FLT: 0 = 33; AF1; FLT: 1: 1 ASA3; IS bahwa rasio gyromagnetic (approxemately 42.58 MHz / T for protons)
  • S01; WAL1; FLT: 0 AF3; B0; B0 1; FLT: 1 ASA3; Y3; INI YANG MAIN magnetic field

Periksa Kalkulation

For a systemm with a 3 Tesla magnet and a target resotunon of 1 millimeteorr (0.001 meters), the comerered gradient is:

11; FLT: 0 ASA3; G = 0.001 × 42.58 × 10 ^ 6 / (21) Syon1; FLT: 1 23;

Kalkulating this gisocutièe 2.26 T / m. Ini gradient Áth enables hig- resolution imaging this magnetic field syh.
