Teknik Praktek for Mitigation

Teknik Severala can help reduce motion artifacts is n MRI images:

  • Pertama; FLT: 0; 33; Patien immobilization: 1f 1; FLT: 1; 1f 3; Using straps, pyrons, or confuints to minimize movement.
  • FLT: 0 = 33; Fast imaging sequences:
  • Pertama, FLT: 0 = 33; Motion mengoreksi algoritmanya: FLT: 1; Applying soft-basec duming reconstruction.
  • Pertama, FLT: 0 Abodil3; Abodil3; Breath-hold tecques:
  • Pertama, FLT: 0 Adeditionai, Navigator echoes:

Kalkulations for Motion Compensavon

Calculations implive estimating the motiot of motion and adjuing imaging paramacs accordingly. For example, the motion displacemt (d) can be estimatech using:

S01; S01; FLT: 0 AF3; D = v × t 1r; S01; FLT: 1 123; 123;
