An x-ray system with an x-ray generating device having improved heat dissipation capabilities. The x-ray generating device has an x-ray tube mounted in a casing holding a circulating, cooling medium. According to the present invention, the x-ray generating device includes a support mechanism mounted within the x-ray generating device in a manner for adjustably positioning, relative to the casing, the focal spot alignment path of generated x-rays. Additionally, the x-ray generating device includes a cooling mechanism having an inlet chamber for channeling the cooling medium within the support mechanism. Additionally, a cooling stem may be positioned within the inlet chamber to increase the heat exchange surface area exposed to the cooling medium. Thus, the present invention advantageously increases the heat dissipation capability of the x-ray generating device.
