2905

An image scanner that reads black and white images of transmissive materials, such as X-ray films, and transfers them as digital data to a computer.

Overview

The laser film digitizer 2905 is an image scanner designed to read black and white images of transmissive materials, such as X-ray films, and transfer them as digital data to a computer. Utilizing laser technology, the 2905 can accurately and quickly scan even the densest areas of film. The USB 2.0 interface ensures high-speed data transfer. The 2905 offers several optional features, including an auto feeder capable of scanning up to 100 films of varying sizes and a roll film adapter for 100 mm-wide roll films. Additionally, when paired with optional scanning software, it can send scanned images to an image server via DICOM/DICONDE communication or easily create high-quality digital duplicates with a DICOM imager.

Features

High-quality scanning

The key to the image quality of a film digitizer is its ability to reproduce dark areas of the image.
The 2905 has a wide dynamic range, supporting optical densities up to 4.3 (or up to 4.7 with the high-density option), excelling in image quality and gradation reproduction.
The laser technology minimizes noise in high-density areas. Subtle gradations in dark regions, which are challenging to reproduce with CCD, are accurately digitized.
Additionally, the 2905 uses an internal 14-bit and 12-bit output (4,096 gradations with linear optical density) A/D converter, providing finely detailed and natural tones.
The pixel spacing can be set from 50 𝜇m to 2,000 𝜇m in 1 𝜇m increments.

Recognized excellence by Germany

The 2905 series was certified by Germany’s BAM (Bundesanstalt für Materialforschung und-prüfung: Federal Institute for Materials Research and Testing) after passing rigorous tests in 2003. It is recognized as the world’s first DS9-grade film digitizer (with the high-density option; DB9-grade with the standard configuration).

Supports long and special-sized films

It can scan long films such as 14” x 42” and films of special sizes.*

* Applies to films with a short side length of 364 mm or less.

High-speed scanning

Scan a half-size film (14” x 17”) in approximately 6 seconds (200 𝜇m, standard mode).
The scanning speed of the 2905 is noticeably faster compared to CCD-based film digitizers.

DICOM and DICONDE communication for scanned images

With optional scanning software, send scanned images to an image server or imager via DICOM and DICONDE communication.

High-quality digital dupe creation

Use optional scanning software and a DICOM imager to create a high-quality “digital dupe” in the same size as the original film.

Create both the digital dupe and send images to the image server in a single scan. There is also a “Copy Mode” that allows you to create a digital dupe without sending it to the image server. The digital dupe includes text indicating it is a dupe.

Functions

  • Provides high-quality, high-speed scanning
  • Supports scanning of long and special-sized films
  • Scan up to 100 films at once (optional)
  • Send to DICOM and DICONDE image servers (optional)
  • Create high-quality, full-size digital duplicates (optional)

Optional

■ Auto Feeder AF3
Scan up to 100 films of different sizes at once. It also allows for single-sheet manual scanning.

■ Scanning software
Scan films with the 2905, add attribute information (worklists), and send it to DICOM and DICONDE image servers. Connect with a DICOM imager to easily create high-quality, full-size digital duplicates.
