AMRI 310 Week 6The multi-turn solenoid, bird cage coil, single turn solenoid, and saddle coil
are typically operated as _________ of RF energy.
-transmit and receive
-receive only
-transmit only - correct answer ✔transmit and receive
Typically surface coils can only ________ signal.
-induce
-overlap
-transmit
-receive - correct answer ✔receive
Cross-talk between slices is avoided or minimized using an RF pulse having a
shape profile as close as possible to a _____ shape.
Select one:
rectangular
bell aka gaussian - correct answer ✔Rectangular
The RF pulse's "center frequency" selects the position of the slice, and its BW
determines the slice thickness (together with the SEG)
Select one:
, True
False - correct answer ✔TRUE
Parallel imaging causes the MRI scanner to sample twice as many phase
encoding steps, thus increasing scan time.
Select one:
True
False - correct answer ✔FALSE
Parallel imaging in MRI is designed to decrease scan time, not increase it. It
allows for the simultaneous acquisition of multiple lines of k-space, reducing
the number of phase-encoding steps needed to form an image. This
acceleration technique is intended to make MRI scans faster and more
efficient.
A fourier transformation is when you take thin axial images, and reformat them
to create another imaging plane such as coronal.
Select one:
True
False - correct answer ✔FALSE
Fourier transformation is a mathematical technique used in MRI image
reconstruction.
It's a process that transforms raw data acquired in the spatial domain into the
frequency domain, and vice versa.
