Aperio GT 450 DX System

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

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

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

Scanner Administration Manager DX (SAM) 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 server after which they are converted to an SVS file or remain as DICOM. SAM 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.

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.

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

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. The Aperio Viewer DX Stations, include monitors that are calibrated and haven been validated for use with the GT 450 DX 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 DX next generation images.

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.

0.26 µm/pixel

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

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.

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.

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.

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.

The Aperio GT 450 DX outputs images as a series of Whole Slide Microscopy Image objects. As the Aperio GT 450 DX scanner is intended to operate as a networked device, it does so by outputting the images using standard DICOM network transfer protocols. The Aperio GT 450 DX scanner can transfer images directly into a customer PACS, which they can then export from their PACS to access the DICOM files.

If you are using a PACS capable of receiving and storing Whole Slide Microscopy Images and a viewer capable of presenting the images, then yes. However, not all PACS vendors support Whole Slide Microscopy Images, and due to the size of these images, not all PACS systems that do will do so with acceptable performance.

Similarly, due to the size of the images not all DICOM viewers will be capable of presenting the images correctly or with good performance. And, as with Aperio SVS file format, the Whole Slide Microscopy Images generated by the Aperio GT 450 DX product family consist of thousands of smaller image “tiles,” and not all DICOM viewers are capable of handling this type of image.

Yes, Leica Biosystems Aperio DICOM Conformance Statement (MAN-0465) is intended to facilitate integration between the Aperio GT 450 DX product family scanners and other DICOM products. It includes detailed information about how the Aperio GT 450 DX produces DICOM files, DICOM functionality, and how that functionality integrates with other devices that support DICOM features.
