Embodiments of the invention provide systems and methods for generating combined image data representing a volumetric image of a subject and a color textured external surface of the subject. First and second configurations for allocating resources are generated, each having first and second degrees of optimization, respectively. It is especially useful in those applications where the desired laser output power can vary over a wide range, including relatively low power above the lasing threshold. The trim cover surrounds at least a portion of the head restraint core. The second support is rotatably connected with the housing. Thus, upon failure of the body at the upper fluid ports, the fishing neck is exposed and can receive a fishing tool for retrieval of the tool and the pump.
