Mesoscope features: real-time panoramas, ROI selection, zoom/pan, and dynamic ROIs

Here are some of the features we have been developing to make it easy to build panoramas, pick regions-of-interest, and to visualize ROI location and data during acquisition using the NLW Mesoscope (aka the Kraken) on the latest version of Scanbox. The video below shows a brief demo of the following: The automatic creation of…

Finding the optimal sample clock phase

Some time ago we talked about the advantages of synchronizing the digitizer sample clock to the laser.  Our new system incorporates an on-board PLL multi-phase clock that allows Scanbox to automatically measure the contrast in a test image as a function of sample phase delay and select the optimal value for your setup. A typical measurement…

Using the correct range and bias for PMT amplifiers

You may have one of two different PMT amplifiers in your setup.  One which has a variable gain. The typical settings of this amplifier should be: left the switch on GND, middle switch on L or H but with the knob set to a gain of 10^4, next switch on FBW and DC for the…

Taking the mesoscope for a test drive

The Neurolabware mesoscope is up and running using our new tower system and today we took it for our first test drive with a tetO mouse. Here is the very first movie sequence of a large FOV with single-cell resolution.   We can also build a panorama of a large region using Lissajous scanning (other…

Intrinsic & epi-fluorescence imaging using the port camera

Some colleagues have asked about the possibility of integrating imaging acquisition from the port camera to do intrinsic and/or epi-fluorescence imaging ahead of targeting a region of interest with two-photon experiments in Scanbox. We have now added this option to Scanbox. To use this  option you will need to wire the I2C port on the…

Sampling on a Surface

Not long ago I mentioned Scanbox’s new ability to sample on a surface. Now you can access this new feature in the GUI by navigating to the Surface Sampling panel. Surface sampling allows you to link lines of the resonant scan to depths determined by the optotune setting.  In other words, it allows you to…

Tiling with Knobby

Knobby scheduler allows the user to move the microscope by specifying a list of relative changes in position at given frame numbers.  One quick way to fill up the table is provided by a set of text fields in the knobby panel.  This allows one to perform (x,y,z) tiling with a given range and step…

Spatial Calibration for Multiple Objectives

Multiple users of the scope may be running projects that require different types of objectives.  How to keep a spatial calibration for each and switch between them when necessary? Scanbox now includes an “objective” configuration variable — a cell array of strings each with the name of a different objective.  Right now I have: Now,…

Visualizing Individual Slices during Volumetic Imaging

During volumetric imaging, Scanbox displays all images as they are acquired. This can be inconvenient if we are trying to visually assess the activity of neurons within any one optical slice.  One solution is to display the images separately in a montage by means of a Scanbox plug-in.  However, it would be better to have…
