X-ray images are collected while the X-ray tube moves through arange of positions, generating images with a range of exposure angles. For example, a standard doctor’s office or small clinic X-ray machine has a movable X-ray tube. Collecting images with exposure angles spanning at least 60o with respect to the subject is desirable.
Principles:
In spite of costs and safety concerns, existing Linear Tomography machines employ the alternative of precisely controlling motion with motor-driven equipment. In this approach, precise knowledge of X-ray tube position and orientation (Pose) is achieved by building a precision machine and making one displacement measurement at each joint of the machine.
Because of the cost of precisely controlling motion of the X-ray tube and subject, the Iconos R 200 is considerably more expensive than a manually moved X-ray machine (one GEMS manager estimates $100K added for the cost of the high-precision X-ray tube motion system). In addition to cost, the automated X-ray tube motion system adds considerable size, weight and complexity to a Linear Tomography system, such as the Iconos R 200.
Equipment:
Application:
For obtaining clear x-ray images of deep internal structures by focusing on a specific plane within the body. Structures that are obscured by overlying organs and soft tissues that are insuffi ciently delineated on conventional x-rays can thus be adequately visualized

Very good job. It's a great start, just be more graphical. Bring on the diagrams.
