2022-06-24 Diagnostic Imaging "Principle of X-rays ①"

Diagnostic Imaging is a class that aims to help students understand the basic principles and characteristics of various diagnostic imaging methods, as well as their clinical applications for animal diseases, and to understand the imaging characteristics of major diseases.
Animal Medical Center, which provides advanced medical care in the Tama region, is equipped with the latest facilities and diagnostic and treatment equipment, and students conduct their training using this equipment.

Today's topic is X-rays!
Divided into groups of 10, the students learned about the principles of X-rays from Associate Professor Kishimoto Kaori.

Using animals for practical training puts a strain on them, so this time Wang uses a ``simulated living body'' to learn the principles.
These are the sweets and musical instruments that everyone had.
In addition to these pseudo-living objects, Wan uses toys, vegetables, and other items carefully selected by each group.

The second photo shows a photo shoot using a musical instrument (viola).
The third photo is an X-ray of Viola, and the fourth is an X-ray of sweets.
How it appears on X-rays depends on the material of the subject, but even the same thing looks different depending on the dose of X-rays and the direction of the subject, so I take pictures by changing the dose and changing the direction of the subject.
In class the following week, the group will look at the images and discuss how the appearance changes and why.

Before the next class, the students look at each image and think about what kind of subject would appear under what conditions and how it would look, and also look up the atomic number of the subject used in the photo shoot.
Just looking up the atomic numbers of the ingredients in chocolate confectionery seems like a lot of work.
Good luck to all you veterinarians out there!
