The replacement of a non-uniformly magnetized core with a set of uniformly magnetized cylindrical elements was made on the basis of preliminary calculations, according to which at b/R [greater than or equal to] 16 the axial projection of [??] in the cross sections of the core along its entire length, except for small sections near the ends, is distributed almost uniformly.
The sensitivity of primary radiography (AP-view, scapular Y and axial projection) in the diagnosis of coracoid fractures is 40%, making these fractures the most occult of the scapula fractures.
* CT scan was performed keeping patient's head in supine position for axial projection with gantry and angle tilt 0[degrees]-10[degrees] in reference to orbitomeatal line, scanning through orbital region.
Radial, axial and tangential projections of the contact zone between the roller and work are made, then the radial projection area Sr, axial projection area Sz and tangential projection area St can be obtained, as shown in the Figure 3 ~ 5.
The Ferguson or AP axial projection satisfies this request.
While the patient continued to receive IV tobramycin and ticarcillin, the radiologist rescanned his head, this time using a coronal projection rather than the standard axial projection (figure 6).
The sinus series included a parietoacanthial projection (Waters method), lateral skull, PA axial projection (Caldwell method) and submentovertical projection (SMV).
This examination was performed as an AP axial projection, 45 [degrees] LPO position.
Due to overlapping shadows of the bony anatomy, loss of articular cartilage in the glenohumeral joint cannot always be visualized using the anteroposterior (AP) projection with internal and/or external rotation or the axial projection. The axial projection and Grashey[1] positions are better suited for defining the extent of cartilage damage.
Three repetitions of each of the projections were saved in randomized order, for a total of 54 axial projections and 54 sagittal projections.
Several axial projections can be used for the evaluation of this problem.
The inferosuperior axial projections (Lawrence and West Point methods) require the patient to be in a recumbent position with the arm abducted, (1-3) These projections are time-consuming for the radiographer and cumbersome to place the x-ray tube in the required positions.
