Abstract:
A diagnostic imaging system comprising:an x-ray tube mounted on a rotating gantry; an x-ray detector disposed across an imaging region from the x-ray tube; and a cooling oil circuit mounted on the rotating gantry which circulates cooling oil over the x-ray tube to remove heat from the x-ray tube thereby heating the cooling oil, the cooling oil circuit including: a means for absorbing heat from the heated cooling oil when a high heat capacity fluid of the means is relatively less heated than the cooling oil and returning the absorbed heat back into the cooling oil when the high heat capacity fluid is relatively more heated than the cooling oil, a bypass line connected in parallel with the means for absorbing heat from the heated cooling oil, and a means for selectively adjusting a proportion of the cooling fluid directed to the means for absorbing heat from the heated cooling oil relative to a proportion of the cooling fluid directed to the bypass line.
