ABSTRACT
Positioning for horizontal beam lateral knee projection. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315382210/8ca82e7c-bd07-4171-b4f5-ebaded57b5b3/content/fig2_48a.jpg" xmlns:xlink="https://www.w3.org/1999/xlink"/>
The patient remains on the trolley/bed, with the limb gently raised and supported on pads.
If possible, the leg can be rotated slightly to centralise the patella between the femoral condyles.
For CR, a 24 cm × 30 cm image receptor is usually used.
The imaging receptor is supported vertically against the medial aspect of the knee with its centre at the level of the upper border of the tibial condyle.
