Geometry parameters

FOV – Read (Frequency) direction

Defines the field of view along the frequency-encoding axis.

GE: FOV Frequency | Siemens: FOV Read | Philips: FOV (Read)

FOV – Phase direction

Defines the field of view along the phase-encoding axis.

GE: FOV Phase | Siemens: FOV Phase | Philips: FOV (Phase)

Foldover direction (Phase)

Sets the phase-encoding direction to manage aliasing.

GE: Phase FOV Direction | Siemens: Phase Encoding Direction | Philips: Phase Direction

Matrix size – Read (Frequency)

Number of samples in the frequency direction, affecting spatial resolution and SNR.

GE: Frequency Matrix | Siemens: Base Resolution | Philips: Reconstruction Matrix (Read)

Matrix size – Phase

Number of phase-encoding steps, influencing resolution and scan time.

GE: Phase Matrix | Siemens: Phase Resolution | Philips: Reconstruction Matrix (Phase)

Number of slices

Total number of acquired slices. When more than one slice is selected, additional slice-management options become available.

GE / Siemens / Philips: Number of Slices

Slice thickness

Physical thickness of each slice.

GE / Siemens / Philips: Slice Thickness

Slice gap

Spacing between slices to reduce cross-talk.

GE: Spacing | Siemens: Distance Factor | Philips: Slice Gap

Plane orientation

Acquisition plane: transaxial (axial), sagittal, or coronal.

GE: Scan Plane | Siemens: Orientation | Philips: Slice Orientation

Multi-slice mode (visible when multiple slices are selected)

Defines the order in which slices are acquired:

• Sequential: slices are acquired in order.
• Interleaved: slices are acquired in an alternating pattern to reduce slice cross-talk.

GE: Slice Order | Siemens: Multi-slice Mode | Philips: Slice Ordering
