Wholeslide.com is the public-facing page for WholeSlide, Inc. - a technological initiative to create novel tools for wholeslide image viewing and analysis. We use bleeding-edge software applied to multitouch hardware with an emphasis on user iteraction. Looking forward, we hope to renovate the dated mindsets formed when access to hardware like the iPad was purely science fiction with a fresh perspective, taking advantage of what the technology can accomplish if it becomes a focus and not simply a tool.

wholeslide for ipad

The WholeSlide iPad app was developed to enable rapid access and rich interaction with large (1 gigapixel + ) wholeslide images hosted online. The app allows users to natively zoom into a wealth of image types: from neuroanatomy and developmental biology to pathology and histology resources.

Basic usage

Select a site from the main menu to show a list of available data sets. Selecting a dataset will present the list of wholeslide images for that set available to view. Sites and sets are organized based on their own internal structure. Some sites are grouped by folder while others are searchable. Selecting an image will load it into the viewer.

Controls

The WholeSlide App provides tools to interact with wholeslide images on the iPad. Individual tools are toggled on and off using the buttons located immediately to the right of the Tile chooser. Tools can be dragged around the screen using their top handle.

Image Metadata: Here you will find pertinent slide data, including species, stain, native resolution, and attribution. We are limited by the information made available via each independent site and are working to increase the depth and breadth of this content.

Image Adjustment: Here you will find controls to adjust the bright, contrast, and RGB windows of the image. Thanks to the processing power of the iPad, we are able to perform these adjustments in real-time on the device itself. The RGB windows allow you to scale the relatively red, green, and blue channels, but the easiest way to understand how the RGB windows function is to try them yourself.

Navigation: Here you will find a thumbnail of the current image, the effective magnification in screen pixels, and a slider pad to quickly move between images within a dataset.


Adding/Remove data

The WholeSlide application contains links to over 70 Terabytes of image data from the start. However, many researchers and clinicians have their data on University-run image servers. Users can add custom sites and data sets within the app itself. We currently support Zoomify-compatible single tiles and sites that provide an RSS feed of the available tiles.
