In phase 1 the participants have measures undertaken in the supine and erect position but just have the standard supine pelvis X-Ray performed. During phase 3 a new cohort of particip

Inclusion criteria

Inclusion criteria: Phase 1: 1. Patients over the age of 18 who attend for x-ray of the hip or pelvis from a MYH OP clinic or their GP 2. Able to stand unaided 3. Have not had lower limb surgery in the last six months 4. Able to provide written informed consent. Phase 3: 1. Patients who over the age of 18 attend for x-ray of the hip or pelvis from a MYH OP or their GP 2. Not pregnant 3. Able to provide written informed consent 4. Able to stand unaided 5. Have not had recent trauma or a pelvic x-ray or pelvic radiotherapy in the preceding 6 months

Exclusion criteria

Exclusion criteria: Patients who are under the age of 18, pregnant, have undergone lower limb surgery within the previous six months or are unable to provide written informed consent will be excluded from the study. A further exclusion will be related to patients who are unable to stand unaided, as the ability to weight bear would be a key component in performance of an x-ray in the erect posture.

Design outcomes

Primary

MeasureTime frame
Difference in abdominal soft tissue thickness, measured by a researcher with a tape measure (in cm) in supine and erect position at baseline (incorporating phase 1 & 3 data).

Secondary

MeasureTime frame
1. Difference in abdominal circumference, measured (in cm) in supine and erect position at baseline (incorporating phase 1 & 3 data) 2. BMI will be calculated using height and weight measurements obtained at baseline (incorporating phase 1 & 3 data). 3. Difference in radiation dose between X-Rays performed in supine and erect position as measured by dose area product (DAP) at baseline (phase 3). 4. Image quality variation between supine and erect X-Rays performed at baseline will be measured using a validated psychometric scale (phase 3).
