Stack Controls
The Stack Controls window allows to define stack acquisition. ScanImage supports multiple modes of defining and executing stacks:
Stack geometry definition
Stack Defintion | Description |
---|
Uniform | Stack is defined by number of slices and slice distance |
Bounded | Stack is defined by top position, bottom position and slice distance |
Arbitrary | Stack is defined by a vector of arbitrary zs |
Stack mode
Mode | Description |
---|
Slow | After each slice, the acquisition halts, the actuator moves the focus, and then continues the acquisition |
Fast | The acquisition is continuous, the actuator sweeps through all slices of the stack |
The 'Enable Stack' checkbox in the main controls window activates stack acquisition for Grab or Loop acquisitions
Slow Stack
 | Control | Description |
---|
Actuator | Actuator that moves the focus. Options are 1) motor 2) fastZ | Return Home | Return to initial position afer the stack acquisition is completed | Close Shutter btwn Slices | Close shutter between slices to limit exposure of the sample while actuator moves. |
|
Fast Stack
 | Control | Description |
---|
Waveform | Waveform shape to drive the FastZ actuator. Options: 1) sawtooth (unavailable for arbitrary zs stacks OR if Frames per Slice > 1) 2) step (ensure the fastZ actuator can settle in time) | Return Home | Return to initial position afer the stack acquisition is completed | Flyback Time (ms) | Flyback time granted to | #Discard Frames | (not settable) number of flyback frames, calculated based on flyback time | Actuator Lag (ms) | lead time applied to FastZ drive waveform to compensate for actuator lag | Volume Rate | Volume Rate [Hz] | Test Waveform | Show the FastZ Tuning Window |
|
 | Control | Description |
---|
Frames per Slice | Number of frames acquired per slice | Number of Slices | Number of slices in stack | Number of Volumes | Number of times the stack is acquired | Step Size (um) | Distance between slices | Centered Stack | Center stack around current z position |
|
Bounded
 | Control | Description |
---|
Frames Per Slice | Number of frames acquired per slice | Number of Slices | Number of slices in stack | Number of Volumes | Number of times the stack is acquired. | Step Size (um) | Distance between slices (auto calculated) | Set/Clear Start | Set / Clear the stack start position | Set/Clear End | Set / Clear the stack end position | Use start end powers | Use the stack start and end powers |
|
Arbitrary
 | Control | Description |
---|
Frames Per Slice | Number of frames acquired per slice | Number of Slices | Number of slices in stack (auto calculated) | Number of Volumes | Number of times the stack is acquired | Arbitrary Zs \[um\] | Vector defining zs | Copy from ROI group | Copy zs vector from ROI refinition |
