Sequence space selection principles

Figure 7.3 Sampling principles in 2D k space (a) Cylindrical coordinates. The angle of the field-gradient direction with respect to the x axis is given by 6= arctan Gy / Gx, (b) Cartesian coordinates. For rectangular gradient pulse shapes ky = -g Gy t1 and kx = -g Gx t2. Such sampling schemes are applicable to a slice which can be selected when the rf pulse is applied selectively in the presence of a gradient Gz. The areas of k space accessible by the pulse sequences shown are shaded in gray. TX transmitter signal ... Figure 7.3 Sampling principles in 2D k space (a) Cylindrical coordinates.
