show | The "unseen" image, the image before it is processed to a "visable" one
🗑
|
||||
Radiation Field | show 🗑
|
||||
show | Remains of the primary beam after it has been attenuated by matter, "Exit Radiation", the pattern of the remnant radiation creates the image.
🗑
|
||||
Scatter Radiation | show 🗑
|
||||
show | The unwanted image exposure caused by the scatter radiation.
🗑
|
||||
show | Or mass, Bone has greater mass, therefore will absorb more radiation than less dense tissue such as fat, this varies the intensity of the X-Ray beam

|
||||
Atom | show 🗑
|
||||
show | Energy that binds electrons to their own shell, electrons near the nucleus have more binding energy than those in outer shells

Circut | show 🗑
|
||||
show | Electric charges that drift or flow in a vacuum, in certain gases, liquids, and metals, connected to make a circut
🗑
