Unit 6 - K Space Flashcards
1
Q
Define k-space
A
an area in the array processor where spatial frequency data are stored
2
Q
Identify what factor determines the number of lines in K-space
A
number of phase encode steps
3
Q
Identify what factor determine number of data points to be collected
A
frequency matrix
4
Q
Describe how lines of k-space are numbered
A
Starting at central line (0 or +1 or -1) counting positively or negatively
5
Q
Identify which gradient changes amplitude (slope) from one TR period to the next
A
phase encoding
6
Q
State how the phase gradient selects each line of k-space
A
by either positively or negatively, or slope amplitude
7
Q
Discuss how k-space is filled from steep and shallow phase encoding gradients
A
from the steep and shallow phase gradient
