Sprawls Shared Visuals for Teaching


Teaching is the process of helping someone learn.  It can be highly effective when it is a collaborative effort between one teacher who is creating and providing visuals and another who is using their knowledge and experience in the classroom to guide the student/learners in mentally exploring  and visually interacting with the physical universe to develop sensory conceptual knowledge networks that support the many applications of physics in medical applications.

Thought out my career as a medical physics educator I have created and used extensive visuals to enhance the learning experience for the students.  Here I am sharing those that might be helpful to others in their teaching activities.
I maintain the copyright on the visuals with permission granted to all educators to use in non-commercial educational activities with acknowledgement of the source (the signature on each image).

 The visuals are organized by the following topics. Click to open file.

Medical Image Characteristics that Affect Visibility
Scattered Radiation and Contrast
X-ray Image Formation and Contrast
Interactions of Radiation and Matter
Radioactivity and Radioactive Transitions
