Document Summary

Projectional images = literally x-rays; photons going through a person; all info is contained into 1 image. Sectional images = ct, mri; whole volume of tissue irradiated & digitized; axial (bottom from top), sagittal (left from right), coronal (back from front) planes of the image. Activity #1 answers: don"t have structures anterior or posterior to the slice that superimpose on the x-ray; left, right, right, right. All images are viewed based on 1 simple principle: Viewing all images assuming the patient is facing towards you standing in front of you in anatomical position. When viewing the image, your right shoulder will be opposite their left shoulder. Viewed the same way as a pa or ap projection. Activity #2 answers: right; coronal, right, axial, right (know b/c fibula is on the lateral aspect); coronal. Viewed same as ap/pa projections; using the simple principle. Won"t be tested on what side of the body is this? .
