A medical device or technique used to restrict or minimize movement of a patient or a specific body part during X-ray imaging procedures. It is designed to immobilize the patient or the area of interest to obtain clear and accurate X-ray images. Immobilizers for X-ray can include devices such as positioning aids, padded restraints, or specialized supports that assist in stabilizing the patient or the body part being examined, reducing the risk of blurring or distortion in the resulting X-ray images. These immobilizers contribute to improved diagnostic quality and help ensure patient safety during imaging procedures.
