4. Avanse Acquisition and Imaging System

Acquisition and imaging workstation Visaris Avanse is the integral component of the VISION M system. It is designed for centralized control of the digital radiography system. It is the control center from which the generator (exposure control, selection of anatomy program) and acquisition and imaging system (patient data, worklist import, image post-processing and DICOM operations) are controlled.

Patient imaging is performed in extremely simple way, maximally adjusted to the needs of an x-ray technologist. User interface is in customer’s language. Five essential steps in workflow are:

  1. Selection of patient
  2. Selection of projections
  3. Exposure
  4. Image processing
  5. Image export and publishing

 

DICOM Modality Worklist integration

Besides the usual way of direct input of patient data the acquisition system supports the import of modality worklists (MWL) in DICOM format from the supported MWL or PACS servers. User interface enables simple query of created MWLs by patient or modality details and their direct import in workflow.

Image processing

The system offers extraordinary post-processing features for visualization of region of interest (screenshot shown in following image). Some of the basic image processing tools are:

  • Histogram (selection of grayscale range for the best view of ROI);
  • Horizontal and vertical image flipping;
  • Zoom in or zoom out;
  • Cropping of ROI;
  • Measurements of distances;
  • Positive, negative view;
  • Exposure index display for every image;
  • Magnification of details;
  • Image archiving on PACS server in DICOM format etc.

 

Software for optimization of image quality

Besides the usual tools for image processing, Avanse acquisition console provides a number of specialized advanced techniques of image post-processing. Visaris ß (Beta) algorithm enables normalization and harmonization of response of grayscale for wide range of exposure parameters thus enabling a way increased sensitivity compared to conventional and CR systems. That way the acceptable image quality, contrast and brightness is achieved in underexposed and overexposed regions. By this multi-frequency processing of X-ray image the structure of bones and soft tissue is enhanced. Predefined parameters of image processing are changeable and the chosen values can be saved.

Printing, archiving and making annotations

The printing module of processed images enables selection of printing media (paper or film), format of media, slection of desire display of rows and columns, and printing of images with annotations showing patient and anatomy details, orientation, exposure parameters etc.
