Where should the primary beam be centred for a VD radiograph of the thorax
Mid-thorax
Describe the patient positioning for a left lateral radiograph of the cervical spine
Patient placed in left lateral recumbency with neck (cervical spine) positioned on the cassette
Small foam wedge placed under nose to correct rotation of the head
Small foam support positioned under neck to correct sagging of the neck
Both forelimbs drawn caudally
Small foam support positioned between forelimbs to ensure that the median plane is parallel to the cassette

Mid neck region
Describe the positioning for a right lateral lumbar spine radiograph
Patient placed in lateral recumbency
With lumbar spine Region positioned on the cassette
Place small foam wedge under the sternum to ensure that median plane of the body is parallel to the cassette
Place small foam wedge under mid-lumbar spine to prevent sagging
