Image Analysis Workstations

• Location: LSN 429 (see map)
• Contact: Doug Cromey, 626-2824
• Administration: Cell Biology & Anatomy
• Fees for use : Currently there are none, however, see below

Reminder: SWEHSC Investigators (including their staff and students) should contact the Cellular Imaging Core directly for advice regarding experimental design, training, and technical support for this instrument.
Proposed Fees:

• Training/Consultation: Members of the SWEHSC can receive
training and consultation on this system at no charge. Other
University of Arizona investigators may be charged a
consultation fee.
• System Use: At some point in the future a fee to cover the
expenses of this system (annual software maintenance
agreement, etc.) may be charged to users.
Light Microscopic & Image Capture Capabilities:

LSN
workstation: The Olympus IMT-2 inverted microscope is equipped
with a digital camera that can capture 1280x1024, 10 bit (1024
intensity or grayscale values) images of brightfield, phase
contrast, DIC and fluorescence (FITC cube) imaging
modes. The microscope has motorized controllers for shutters, microscope
filters and x-y-z stage control. The automated stage has holders
for microscope slides, 35mm culture dishes and 96 well plates (note:
DIC imaging uses polarization and cannot be performed through plastic). A BiopTechs
Delta T3 system for keeping 35mm culture dishes at 37°C
enables the system to be able to capture time-lapse images of cultured
cells over periods of several hours. A copy of Adobe Photoshop version
6.0 is available on the computer. The workstation
computer was upgraded (larger hard disks, Core Duo processor) in May
2007 and
this included an upgrade to the latest version of the SimplePCI
software. In addition, a quantitative FRET module was added to
the software. This upgrade was paid for out of the Cellular Imaging
Core budget.
AZCC
workstation: The Arizona Cancer Center workstation is
located in room 3964 (see map).
This workstation has a SPOT-Jr color digital camera mounted
on an upright Nikon T-200 brightfield microscope. The dual-processor
workstation has 2GB of RAM and can save data to a 250MB
ZIP drive or CD/DVD burner.
Image Analysis & Measurement Capabilities:

The
workstations use the SimplePCI software (CImaging
Systems, by Compix, Inc.). Digital images captured from any appropriately
calibrated source (e.g. confocal, TEM, SEM, and other microscopes
or scanned images) can be analyzed by the software. The software
has the capability to measure a large number of parameters related
to size, shape, intensity and position. In many instances the
software can configured to be acquire measurements in a semi-automated
mode. Basic statistical measurements are included in the software.
Numerical data can be exported as Microsoft Excel spreadsheets.
The software has been used to measure/capture:
• The distance traveled by cultured cells over time (time lapse)
• The length of dendrites (confocal images)
• Calculate pH based on using color ratios from SNARF dyes
(Zeiss
confocal images)
• Point counting
in lung tissue (light microscope images)
• Image montages of whole
cross-sections that were later used
for 3D reconstruction or poster presentations (light microscope
images)
• Create time-lapse
movies for presentations (light microscope images)
• Count fluorescently
stained nuclei to measure migration in a
matrix
(fluorescence microscope images)
• Measure sizes of intestinal villi in histologic samples (light
microscope
images)
• Measure
the area of lipid droplets found in Oil Red O stained
histologic
samples (light microscope images)
• 3D
rotations of multi-level/Z-stack images (light
microscope images)
• Automatically count
the number of migrating cells in a transwell assay (24 well
plates).
