the Slice select gradient (SSG) amplitude will either increase or decrease resulting in a relative tilting of the magnetic field
Slice thickness refers to the thickness of the image slices or sections that are produced by a medical imaging device such as a CT (Computed Tomography) scanner, MRI (Magnetic Resonance Imaging) machine, or ultrasound equipment. It is the distance between adjacent image slices as they appear in the reconstructed image.
The slice thickness plays a crucial role in determining the accuracy of the diagnosis and the quality of the final image. A thicker slice may miss small details and lesions, while a thinner slice can provide higher resolution and exceptional detail of the structures.
For example, a thinner slice thickness of 1-2mm is usually used in high-resolution imaging, especially for brain imaging or fine bone structures, whereas a thicker slice thickness of 5-10mm might be used in situations where a quick screening of large areas such as the chest or abdomen is required.
The optimal slice thickness also depends on the specific clinical indication, patient size, and imaging modality. In general, thinner slices are preferred when a high level of detail is required, while thicker slices may be used for a quick and preliminary assessment.
