Reading images
To view and analyze images, use the Image area tools.
- Image area: Basic tasks
  The Image area combines all image display, manipulation, and enhancement tools for reading in Agfa HealthCare Enterprise Imaging.
- Calibrating images
  Calibration refers to how image information is translated from on-screen pixels to real-world measurements. You can calibrate images with the calibration line and the calibration circle tool.
- Showing and hiding patient demographics
  Study images can be displayed with or without patient demographics.
- Hanging protocols, presentation groups, and viewports
  A hanging protocol is a logical set of instructions for displaying the images in a study. Hanging protocols contain one or more presentation groups, and each presentation group contains one or more viewports.
- Image information
  Information about study images, such as patient demographics, CAD SR markers, and image type, can be viewed in the Image area.
- Snapshots: Concepts
  An image snapshot stores the state of images in the Image area and allows you to return the Image area to the same state later.
- Configuring the display of ECG overlays
  XA images can contain overlays that can be configured to be shown or hidden.
- Key images
  Key images identify the most clinically relevant images in a series.
- Mammography
  The Image area provides mammography-specific functionality.
- Measurements and annotations (markups)
  Image area Markup tools calibrate images, take measurements, and highlight and annotate areas with arrows or text. You can also hide, modify, or delete markups.
  - Markup basics
    All markups share the same, basic interactive behavior. You can move or resize them with a few easy steps. Markups also provide the option to show measurement information.
  - Drawing a 2-point circle markup
    Use the Circle (2-points) markup tool to annotate or measure a circular region of interest.
  - Drawing a 3-point circle markup
    Use the Circle (3-points) markup tool to annotate or measure a circular region of interest.
  - Drawing an ellipse markup
    Use the Ellipse (2-points) markup tool to annotate or measure an elliptical region of interest.
  - Displaying group statistics
    You can display common statistics for a group of markups.
  - Naming a markup
    You can edit the name of an annotation or measurement markup.
  - Drawing a rectangle markup
    Use the Rectangle markup tool to annotate or measure a rectangular region of interest.
  - Drawing an arrow
    Use the Arrow markup tool to point to a region of interest.
  - Annotating an image
    Use the Text annotation markup tool to highlight an aspect of the study.
  - Measuring angles
    Use the Angle markup tool to measure an angle in an image by drawing two lines that do not intersect.
  - Measuring distances
    Use the Distance measurement tool to measure the distance between two points.
  - Creating a ratio measurement
    Use the Length ratio tool to measure the ratio of one line to another.
  - Displaying a histogram
    Select a region of interest and display a histogram graph showing the frequency of pixel values inside that region by using the Histogram tool.
  - Creating an intensity profile
    Use the Value profile tool to create a graph that illustrates the values of the image pixels intersected by a drawn line.
  - Creating a shutter
    The rectangular shutter tool can be used to mask or black out portions of an image (usually the outer edges) so that a particular area is the focal point for viewing.
  - Accuracy of measurements
    Various factors affect how accurate Image area measurements area.
  - Measuring the area of an ROI
    Use the Area markup tool to measure the area of regions of interest (ROI).
  - Orthopedic measurements
    Ten orthopedic markup tools are available.
  - Ultrasound measurements: Reference
    Several tools are available for taking ultrasound measurements.
- Navigate images
  You have many options for navigating through the images in a study.
- Panning and zooming images
  Adjust the position and the magnification factor of images.
- Rotating images
  You can adjust study images that are not correctly oriented by applying the appropriate Rotation or Flip tool.
- 3D visualization
  Volume rendering visualizes 2D slice images as a 3D volume. Tools—including free rotation, color-coded enhancement of intensities, and clipping plane sliders—provide advanced decision-making support.
- 3D synchronization
  The 3D sync tool provides 3D synchronization of two or more series without changing the layout or applying a new hanging protocol. 3D synchronization aligns multiple series in one space.
- Volume segmentation
  The Image area volume segmentation tools allow you to define structures that have to be measured, as well as to define structures to be hidden or to visually enhance specific parts within a volume.
- Reconstruction
  CPR reconstructs curved planes defined by a longitudinal axis. MPR reconstructs axial, coronal, sagittal, or oblique views from slices in any of these planes.
- Multi 3D
  Multi 3D series consist of slice image data acquired at multiple points over time. You can scroll through or automatically play back multi 3D series.
- Comparison studies
  Comparison studies contain prior imaging to provide a full patient history.
- Window level
  Enterprise Imaging includes functionality that enables you to adjust the brightness and contrast of an image for diagnostic viewing or to better visualize images by applying a color schema.
- Selecting an SUV calculation method
  Three Standard uptake values (SUV) calculation methods are available for PT images: body weight (SUVbw), body surface area (SUVbsa), and lean body mass (SUVlbm).
- Nuclear medicine: Applying color palettes
  With specific color lookup tables stored as window level presets, you can highlight certain features of a grayscale NM/PET study. You can further adjust the display with the nuclear medicine color bar.
- Splitting multi-phasic CT series
  To split a series that contains multiple phases into several series that each contain one phase, use the Split series tool.
- Presentation states
  A presentation state is a set of display attributes that you apply to an image. You can save and load presentation states.
- TOMTEC IMAGE-COM integrations: Concepts
  The integration of IMAGE-COM, a cardiology study viewer powered by TOMTEC Imaging Systems, into Agfa HealthCare Enterprise Imaging extends the functionality of the Image area with additional analytical tools and features.

Displaying a histogramTopic number: 1425412365865

Select a region of interest and display a histogram graph showing the frequency of pixel values inside that region by using the Histogram tool.

WARNING!

Histograms are calculated based on pixel values representing data values. These do not change if window leveling or other post-processing is applied to the image. Do not rely on histograms alone for making a diagnosis.

To display a histogram

From the Image area top toolbar, click Distance measurement > Statistics > Histogram.
Click to place the first handle to start defining the region of interest.
Click to place further handles to define the outline of the region.
Double-click to place the last handle, completing the outline.
Press Esc to deactivate the histogram tool.

A histogram graph calculated based on the pixel values in the selected area is displayed. The x-axis displays the range of pixel values contained in the region of interest (for example, for CT this is Hounsfield units). The y-axis displays the frequency of each pixel value within the region of interest.
