Excellent Image Quality for Pathologists

The Aperio GT 450 uses a high-performance 40x objective manufactured by Leica Microsystems, that has produced world class optics since 1847. This historic craftmanship is now built into the today’s Aperio GT 450, which is designed to rapidly deliver images with exceptional quality for Pathologists.

  • Leica optics deliver exceptional image quality
  • Every slide is calibrated during scanning to ensure the best quality image
  • Automated image quality assessment so you don’t have to send slides back for re-scans
  • 99.5% accurate tissue finder finds faint tissue while excluding pen marks, dust, and residue

"I have been really impressed with the sharpness and contrast of the images. It is definitely next-generation image quality." Professor of Pathology, UCLA

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

Excellent Image Quality with Custom-Made Leica Objective

The high-performance objective included with the Aperio GT 450 is specifically designed to maximize field of view for high speed digital pathology scanning. Most objective are designed similar to the human eye: round, which focuses light in the center and limits field of view. The objective on the Aperio GT 450 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.

Introducing the Aperio GT 450 (click to play video; turn speakers up)

    Frequently Asked Questions

    Aperio GT 450

    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 has a scalable IT architecture solution …where a centralized SAM server is used to set up and monitor multiple GT 450 scanners from the IT professionals' office.

    What is a SAM server?

    Scanner Admin Manager (SAM) is a high performance server installed in the IT room that enables a centralized admin hub that is connected to multiple GT 450 scanners in the pathology lab. The GT 450 scanners stream DICOM files to the SAM server after which they are converted to an SVS file. SAM includes Mirth for data and event handling and HL7 for integration. SAM server client application software is loaded on the SAM server and enables IT professionals and lab directors to log in via secure network access and then set up and monitor GT 450 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 GT 450 will automatically scan the entire slide.

    Do I need to perform pre-snaps?

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

    Do I need to use calibrated monitor?

    Yes, GT 450 images are designed to be viewed on calibrated monitors for the best possible viewing experience as it relates especially to color. We highly recommend that you use the Aperio Viewing Stations, which include monitors that are calibrated and haven been validated for use with the GT 450 images. The Aperio viewing station includes a proprietary image color correction (ICC) profile on the workstation that calibrates the monitor for use with GT 450 next generation images.

    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 slide racks compatible with other devices from Leica Biosystems

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

    Note: HistoCore SPECTRA workstation ST Stainer, and HistoCore SPECTRA workstation CV Coverslipper, in combination with the Aperio GT 450, are for Research Use Only (RUO).
