IMAGE PROCESSING
Virtual Workshop Series
CT image analysis involves many different kinds of image processing, including denoising, sharpening, reconstruction, morphology operations, etc. If you have been treating them as a "black box," and it's been bothering you, this workshop series is for you.
We reviewed the theories behind these image processing techniques and applied them to sample data using widely available tools like ImageJ and Dragonfly while interacting with the live audience. You can download the sample images and companion eBook and try the hands-on exercises while watching the workshop.

1. Processing Images Using ImageJ
You have probably applied some form of image processing to your CT data, such as denoising or smoothing, before. Have you ever wondered how it works or what is different between different denoising techniques? In this workshop, we will review how these image processing techniques work and how to choose the right one. This is an interactive workshop. We will demonstrate some of the techniques using ImageJ. You can download the sample images and follow us through the process and ask questions.
Presenter: Aya Takase | Co-presenter: Angela Criswell | Host: Tom Concolino
2. Refining Segmentation Using ImageJ
No matter how you process your CT data, you might see some islands and holes in the segmentation. How can we refine these segmentation results? In this workshop, we will review morphological operations and see how they can be applied to refine segmentation results. This is an interactive workshop. We will demonstrate some of the techniques using ImageJ. You can download the sample images and follow us through the process and ask questions.

3. Demystifying Reconstruction Using ImageJ
Have you ever wondered how exactly CT images are reconstructed? In this workshop, we will review how the filtered back-projection reconstruction works and experiment with some sample images. This is an interactive workshop. We will use ImageJ to generate Radon transforms, sinograms, and reconstructed images. You can download the sample images and follow us through the process and ask questions.

4. Image Processing Using Dragonfly
We have been using ImageJ in this series. You might be wondering, "What are the benefits of using commercial software?" In this workshop, we will use Dragonfly software by Object Research Systems and review more advanced image processing techniques and the benefits and convenience of using a commercial software specifically designed for CT image analysis. You can download the sample images and follow us through the process and ask questions.
