2.2 The StreamSync Acquisition Engine World
We are used to concept that an image has an X and a Y dimension. The Acquisition
Engine expands on this concept by adding two further dimension Z and V. The Z
dimension controls a sequence of frames or “Volume” of frames. The V dimension
controls a sequence of volumes, or “Hypervolume”. Figure 2-1 illustrates these con-
cepts.
Figure 2-1 StreamSync Acquisition Engine Dimensions
The size of the X window, i.e. the number of pixels per line, is controlled by the X_SIZE
register. The size of the Y window, i.e. number of lines per frame, is controlled by the
Y_SIZE register. The size of the Z window, i.e. number of frames per volume, is con-
trolled by the Z_SIZE register. Finally, the size of the V window,i.e. number of volumes
to acquire, is controlled by the V_SIZE register. Note that the size of the Y window and
the Z window can be dynamically controlled by external triggers, see below for more
details.
2.2.1 Controlling the StreamSync Acquisition Engine
Acquisition of images is controlled by the AE_RUN_LEVEL register. The run level con-
trols the conditions under which the Acquisition Engine will start or stop acquiring
image data. Acquisition can be idle, which means nothing will be acquired, or it can
be running, which means data will be acquired when the engine is inside the V, Z,Y
and X windows. There are various conditions which control whether the engine is
inside or outside of these windows.
