Processing Overview

Working in the PFUS tool with the combined matching layout typically has the following workflow.

1. Data Loading

Load one or more input image series. These series are automatically resliced to the reference using information in the image headers.

Load the reference images. They define the final resolution of the matched images.

2. Matching Initialization

Improve the initial alignment of the images before starting one of the automatic matching methods.

Test the different available initializations such as aligning the data set origins, the image volume centers, the center of gravity or hot spot.

Shift and rotate the input images manually to come into a reasonable alignment.

3. Automatic Matching

Select an appropriate matching method, rigid or elastic.

Initialize the matching parameters by selecting one of the presets reflecting different situations (human « animal, intra-modality « multi-modality).

Start the matching algorithm.

4. Results Inspection and Adjustment

Visually check the alignment, either on the Initialize/Match page, or on the Fusion page.

Perform the check in different parts of the volume and with different fusion renderings.

In the case of rigid matching the result can be fine tuned interactively, preferably on the Fusion page.  

5. Results Saving

Save the transformation and its inverse in order to re-apply them to the original images or to VOIs at a later time.

Save the matched images for further analysis using the save icon in the lateral taskbar.

6. Image Analysis and Results Documentation

With the resulting images perform the different types of analysis which are possible in the PFUS tool.

Save these results and create reports
