Tissue Pattern Tracking

BlocDoc provides histology teams streamlined workflows that automatically capture macro images of the cut blocks and raw slides providing Pathologist the images they need to verify their slide examinations.

Does Your Lab Assure Tissue Completeness?

Pathologist are great at making diagnostic determinations on the images and data they view.  Now consider for a moment if not all the tissue is being viewed…

… Pathologist cannot diagnose what they cannot see!

Pathology societies around the world have recognized that tissue maybe missing from the final slide or WSI image impacting the diagnosis made 1,2. As a result, accreditation checklists 3,4,5 have been updated to include a requirement for a tissue tracking and review process asking the question...

Does the Lab have a quality check to assure
that relevant tissue is:

1.       Being cut from the block

2.       Making it onto the raw slide

3.       Is present in the final stained slide

4.       Is scanned into the whole slide image

Pathologist and pathology directors would like to answer these questions, but in the face of falling reimbursement and rising caseloads, they do not have the resources to manually audit the hundreds of blocks and raw slides that pass through their labs every day.

In the current workflow…

...What Should be done, Can’t be done.

No Pathologist or laboratory director should be faced with this compromise. Solving this problem isn’t about heroics and staff overtime, it is about having an efficient tool that fits your process and provides clear reference images during the slide examination.

BlocDoc Addresses Pathology Requirements

SPOT Imaging combines 54 years’ experience and a dedicated pathology focus to bring you, BocDoc™ The New Standard in Paraffin Block and Slide Documentation.

BlocDoc meets accreditation checklist requirements by providing pathologists digital reference images of the cut block and raw slides at the time of slide examination (glass or WSI).

BlocDoc provides enhanced image review of the:

      • Cut Surface of the Paraffin Block
      • Below Surface Tissue in the Paraffin Block
      • Raw Slide Tissue Levels

BlocDoc also provides reference labs an efficient tool for documenting incoming tissue blocks and slides providing an accurate record of what has been received.

Missing Tissue

Note the subsurface tissue (circled) that is in the paraffin block that did not make it on to the slide for examination. BlocDoc images provide clear digital documentation enhancing both the cut surface and the subsurface tissue.

Work Flow

Streamlined for the Histology Lab

BlocDoc not only meets the needs of the accreditation checklist, it meets the needs of the personnel using it by providing…

Streamlined Workflow

BlocDoc is an automated image capture system optimized for the Histology workflow. For the microtomist, it is as simple as placing the block onto the sample holder and pushing the trigger button. This is typically a 2 second operation that allows the microtomist to return to their work until they are ready to place the next block or slide.

 

In the background, BlocDoc takes care of the image acquisition…

• First, a set of reflected and polarized light images are captured.

• Next, the sample barcode is captured and decoded.

• Lastly, BlocDoc automatically saves the images to the image repository based on the barcode information captured.

Full Sample Support

BlocDoc is one instruments that is quickly converted to run standard blocks and slides to one that runs whole mount blocks and slides. The sample holders change out in less than 5 seconds allowing even short runs of whole mounts to be easily accommodated on any BlocDoc instrument.

Enhanced Images for the Pathologist

BlocDoc’s enhanced images provide the pathologist with a virtual solution that is better than having the physical specimen block in hand.

Clarifying the View

BlocDoc’s patented* imaging process provides enhanced views of the block’s cut surface as well as views of the subsurface, uncut tissue. This eases the visualization of what tissue made it to the slide and what tissue is still in the block. Additional images provide documentation of the raw unstained slide tissue, supporting reviews of each tissue level before staining. This eliminates the hesitance that previously accompanied the manual retreval of blocks for review. The result is greater confidence in calling for recuts or rescans dictated by missing tissue. The BlocDoc system not only makes the tissue review process more convenient it makes the review clear.
