Projections/Position
Radiographic Projections & Positons
| Question | Answer |
|---|---|
| The term defined as the path of central ray as it exits the x-ray tube and goes through the patient to the IR is called a what? | Projection |
| During this projection a perpendicular central ray enters the anterior body surface and exits the posterior body surface is known as what projection? | Anteroposterior-AP |
| During this projection a perpendicular central ray enters the posterior body and exiting the anterior body surface. | Posteroanterior-PA |
| During this projection, there is longitudinal angulation of the central ray with the long axis of the body or a specific body part. | Axial projection |
| This term refers to all projections in which the longitudinal angulation between the central ray and the long axis of the body part is 10 degrees or more. | Axial |
| Occasionally the central ray is directed toward the outer margin of a curved body surface to profile a body part just under the surface and project it free of superimposition during this projection. | Tangential |
| During this projection, a perpendicular central ray enters one side of the body or body part, passes transversely along the coronal plane and exits on the opposite side. | Lateral projection |
| During this projection, the central ray enters the body or body part from a side angle following an oblique plane. | Oblique projection |
| If the central ray enters the anterior surface and exits the opposite posterior surface, it is known as what projection? | AP oblique projection |
| If it enters the posterior surface and exits anteriorly, it is known as what projection? | PA oblique projection |
| The overall posture of the patient or the general body position is termed as what? | Position |
| Erect or marked by a vertical position. | Upright |
| Upright position in which the patient is sitting or stool. | Seated |
| Lying on the back | Supine |
| Lying face down | Prone |
| Supine position with the head tilted downward | Tredelenburg's position |
| Supine position with the head higher thant the feet. | Fowler's position |
| General term referring to lying down in any position. | Recumbent |
| A recumbent position with the patient lying on the left anterior side (semiprone) with the left leg extended and the right knee and thigh partially flexed. | Sim's position |
| A supine position with the knees and hip flexed and thighs abducted and rotated externally, supported by ankle supports. | Lithotomy position |
| This position refers to the side of the patient that is placed closest to the IR. | Lateral position |
| This position is achieved when the entire body or body part is rotated so that the coronal plane is not parallel with the radiographic table or IR. | Oblique position |
| Term used to indicate that the patient is lying down and that the central ray is horizontal and parallel with the floor | Decubitus position |
| This position is achieved by having the patient lean backward while in the upright body position so that the shoulders are in contact with the IR. | Lordotic position |
| This term is used to describe the body part as seen by the IR. | View |
| This term describes the specific radiographic projection that the individual developed. | Method |
