A weightbearing simulation assembly includes a substrate comprising a mounting surface extending in a first direction a subject support disposed on a first region of the mounting surface and a pedal assembly disposed on a second region of the mounting surface. The pedal assembly includes a spring assembly including a contact plate facing the subject support, a compression plate, and a first spring disposed between the contact plate and the compression plate. A subject applies a compressive force to the contact plate in a compression direction to simulate a load-bearing condition by compressing the first spring. An orientation of the pedal assembly may be adjusted to change a relative angle between the compression direction and the first direction to alter an imaging angle.
