Data acquisition, visualization and analysis
Canvas has the ability to accurately measure, analyze, and export digital images that may contain up
to 32 bits per channel of data.
Specialized imaging instrumentation within the medical, geological, and other related scientific
industries often creates image or data files that may contain more than 16 bits of data per grayscale
channel. Canvas now combines its professionally engineered technology core with a number of new
interface improvements that target the need to study and analyze this information.
Working with DICOM images
Commonly used in medical imaging, DICOM (DIC) files can be imported into Canvas for further study.
Combine the DICOM import filter with the Canvas tools, various image filters and adjustments along
with its slide show capabilities to create dynamic medical presentations. You can even export your
findings to HTML.
DICOM import options
A DICOM file may consist of one or many images. Canvas can read DICOM files as follows:
RGB images are imported as RGB and grayscale are imported as grayscale.
Indexed images are converted to RGB.
Depending on the image’s range, it will be converted to 8bit, 16 bit, 32 bit, or 64 bit images.
To import DICOM files:
1. Choose File | Open, File | Place, or Image | Import.
2. In the DICOM Import Options dialog box, select one or more of the following:
Distribute among layers: Select this option to place each image on a separate layer in
the same document.
Stack together: Select this option to place the images on top of each other.
Create spreadsheet: Select this option to create a matrix of the various images. Define
the number of rows and columns.
Create animation/slide show: Select this option if you want to create a presentation or
export as an AVI file.
