Methods, systems and devices are disclosed for reducing the motion of a body part during a medical procedure that requires stability of the body part. In one example, the device consists of an object which has been customized so that it conforms to an individuals anatomy. When placed on an individual, the device stabilizes their body during medical imaging or intervention. Virtual targets within the body can be localized as physical locations on the body by adding markers on the device. These markers can be quickly and easily localized across multiple treatment sessions. Because the device is customized for each individual, it is comfortable yet effective.
