X-ray Images and the Image Database David Hall, Associate Professor in the Radiology program, has found a great way to link his interest in photography to providing needed x-ray images for student learning in his web-enhanced Radiographic Pathology course. Professor Hall uses the Image Database tool as a way for students to learn about radiographic appearances of specific diseases. Students can view hundreds of x-ray images by clicking on the Image Database from the Radiographic Pathology coursepage:
Professor Hall has accumulated hundreds of x-ray images from a variety of resources, some of which include his own. Using Photoshop, he reworked each image by adjusting the clarity and the size of each x-ray image. "I have always had an interest in photography and digital software editing so this was a great way to capitalize on something I already knew." Using the Image Database Tool, he has uploaded each image into the database based on a category he defined. Along with each image, he provided a title, several keywords (students can actually search the database for images) and a teaching and learning description that was appropriate to the image. In many cases he has added arrows or circles to image to pinpoint a particular condition within the x-ray. When students click on the Image Database from the course homepage, they see a list of categories from which the x-rays are organized. Clicking on one of the categories, the students sees the entire list of x-rays. To get a larger image, the students lick on "View Image" and a larger version of the x-ray appears:
Professor Hall began this project out of frustration with how x-ray images are portrayed in textbooks or other resources. "A lot of the x-ray images were just that-images with little or no explanations. Students would look at an image, but not really see the particulars of the condition". By using Photoshop and the Image Database, he can focus on what is important within each x-ray image and avoid student confusion or uncertainty.
