Precision, Potential to Scale, and Peace of Mind

Digital pathology scan speeds have not always been fast enough at 40x magnification to keep up with high-volume scanning (120k+ slides per year). Real-Time Focusing (RTF)** offers a potential solution to this problem. It’s a novel method to capture a digital image that combines an imaging line sensor and a focusing line sensor.

  1. While scanning, the focusing line sensor receives focusing data of the tissue.
  2. Proprietary algorithms determine the best focus value.
  3. Then, each best focus value is treated like a control loop with the mechanics, feeding the best focus value to the objective height on the fly.
  4. The positioning adjustments of the objective are performed continuously (in real time) in order to enable the imaging line sensor to capture the image at its best possible focus. Hence, real time focusing.

Excellent Image Quality with Custom-Made Leica Objective

The high-performance objectives included with the Aperio GT 450 DX is specifically designed to maximise field of view for high speed digital pathology scanning. Most objectives are designed similarly to the human eye: round, which focuses light in the center and limits field of view. The objectives on the Aperio GT 450 DX includes an extra-wide flat field correction that enables a much larger field of view (1mm) that can accommodate extremely large digital images for fast scans and 0.26 um/pixel resolution at 40x magnification.

Frequently Asked Questions

Aperio GT 450 DX
How many slides per hour can it scan?

81 slides per hour @ 40x (15mm x 15mm area).

What is the scan speed?

32 seconds at 40x for 15mm x 15mm area

Does it have a workstation?

No, Aperio GT 450 DX has a scalable IT architecture solution …where a centralize SAM DX server is used to set up and monitor multiple GT 450 DX scanners from the IT professionals' office.

What is a SAM DX server?

Scanner Administration Manager DX (SAM DX) is a high-performance server installed in the IT room that enables a centralized admin hub that is connected to multiple GT 450 DX scanners in the pathology lab. The GT 450 DX scanners stream DICOM files to the SAM DX server after which they are converted to an SVS file or remain as DICOM. SAM DX includes Mirth for data and event handling and HL7 for integration. SAM DX server client application software is loaded on the SAM DX server and enables IT professionals and lab directors to log in via secure network access and then set up and monitor GT 450 DX scanners in the lab, including dashboard status views, PIN controls for each scanner and log out times for each scanner.

Can I adjust the tissue finder?

Yes, in the rare case you need to adjust the tissue finder, the user can simply select “Scan Entire Slide” and the Aperio GT 450 DX will automatically scan the entire slide.

Do I need to perform pre-snaps?

No, this is automated with the Aperio GT 450 DX because it uses Real-Time Focusing.

Do I need to use calibrated monitor?

Yes, Aperio GT 450 DX images are designed to be viewed on calibrated monitors for the best possible viewing experience as it relates especially to color. Aperio WebViewer DX and FDA-cleared monitors have been validated for use with Aperio GT 450 DX generated images. Aperio WebViewer DX includes a proprietary image color correction (ICC) profile that calibrates the monitor.

Is every slide calibrated during scanning?

Yes, during each scan, the scanning workflow includes a system calibration. This calibration is included in the 32 sec scan speed at 40x for a 15mm X 15mm area.

What is the resolution?

0.26 µm/pixel

Does it offer continuous loading while scanning?

Yes. This unique open face design allows up to 14 additional racks to be added or removed while scanning is in progress.

Are the Aperio GT 450 DX slide racks compatible with other devices from Leica Biosystems

Yes, these racks can be used across 3 of our devices, including Aperio GT 450 DX, HistoCore SPECTRA workstation ST Stainer, and HistoCore SPECTRA workstation CV Coverslipper.

DICOM
What is DICOM file format?

DICOM (Digital Imaging and Communications in Medicine) is a standard for medical image interchange that includes support for transmission and storage of medical image data.

How is DICOM used?

It can be used to transfer data from a Picture Archiving and Communication System (PACS) into some other system, produced by any number of vendors who choose to implement that standard, or used to provide access to clinical data without granting that person access to the entire PACS, or to share medical image data with a patient or colleague, or for long-term archival purposes.

Why is DICOM important?

DICOM is an open, vendor-agnostic standard for medical image data. While many vendors participate in the creation of this standard, it is not controlled by any one vendor. As an open standard, it may be implemented by any vendor and enables interoperability between systems.

Is there a Universal DICOM file for Digital Pathology?

The DICOM standard provides a definition for Whole Slide Microscopy Images, commonly referred to as a “Supplement 145 image” (after the DICOM Supplement which initially defined the image) or “Working Group 26 image” (after the DICOM Working Group which produced Supplement 145). As this standard is intended to be usable by manufacturers of both tiling and line scanning systems, as well as different modalities (e.g. oil, fluorescence, brightfield), it provides vendors multiple ways to produce images that are conformant to the standard, but may not necessarily be compatible with a given vendor’s PACS or viewing software.
