Basic Patient Position The patient lies supine on the table with the midsaggital
line in the center of the table.
The affected side is raised 45 degrees and supported on pads
with the legs extended or minimally flexed to aid support.
A second projection may be made with the patient rotated
45 degrees onto the affected side and the central ray directed
to a point midway along an imaginary line from the ASIS to the
symphysis on the affected side.

There are many local rules for gonad protection however the
following should be taken into account. The 28 day rule should
be applied for female patients.
In males direct lead rubber gonad protection can be applied at
In females direct lead rubber gonad protection is generally not
advised on the first examination, however if the patient is
subsequently examined gonad protection may be used if the area
of interest is not obscured.
On small patients the omission of a grid will reduced the

Evaluation of the Image
ID and markers must be present and correct in the appropriate
area of the film
Evidence of collimation on four sides equally around the
Optimal exposure should penetrate all the bone structures and
contrast should be low enough to visualise fully the bone and
soft tissue structures.
The femoral head and neck should be in profile with Acetabular
margin and fovea well delineated.
