6511224, Jan 28, 2003

Filed:

Oct 18, 2000

Appl. No.:

09/691015

Inventors:

Qing Kelvin Lu - Aurora IL
Gerald J. Carlson - Aurora IL

Assignee:

Koninklijke Philips Electronics, N.V. - Eindhoven

International Classification:

H01J 3510

US Classification:

378199, 378141

Abstract:

A cooling oil circuit (D) circulates cooling oil over an x-ray tube absorbing its waste heat. A refrigeration circuit (E) then cools the cooling oil. A heat buffer ( ) absorbing peak heat loads from the cooling fluid when the x-ray tube is generating x-rays. Valves ( ) regulate a relative amount of cooling oil entering the heat buffer to increase heat transfer efficiency. The heat buffer enables the system to handle peak heat loads with a smaller, more condensed refrigeration system, by absorbing heat during operation of the x-ray tube and releasing heat between operations.

International Classification:

H01J 3510

US Classification:

378125, 378121, 378131

Abstract:

An x-ray tube ( ) includes an evacuated envelope ( ). Mounted within the evacuated envelope are a cathode ( ) and a rotatbly supported anode ( ).

International Classification:

H01J 3510

US Classification:

378141, 378127, 378130

Abstract:

An x-ray tube assembly ( ) includes a housing ( ) and an insert frame ( ) supported within the housing ( ), such that the insert frame ( ) defines a substantially evacuated envelope in which a cathode assembly ( ) and a rotating anode assembly ( ) operate to produce x-rays. The rotating anode assembly ( ) includes an anode target plate ( ) coupled to a rotor ( ) and bearing shaft ( ), which is rotatably supported within a bearing housing ( ), by a plurality of ball bearings ( ). A heat barrier ( ) substantially surrounds the bearing housing ( ) and is coupled, along with the bearing housing ( ) to an anode cold plate ( ). The anode cold plate ( ) includes a grooved cover ( ), a basin ( ), and a plurality of corrugated fins ( ) disposed therein. Coupling both the bearing housing ( ) and the heat barrier ( ) to the anode cold plate ( ) provides an effective means for cooling the bearing assembly ( ).

US Classification:

378 4, 378137, 378124

Abstract:

It is described an X-ray tube () for moving a focal spot within a wide range. The X-ray tube () comprises a first electron source (), which is adapted to generate a first electron beam projecting along a first beam path (), a second electron source (), which is adapted to generate a second electron beam projecting along a second beam path () and an anode (), which is arranged within the first beam path () and within the second beam path () such that on a surface () of the anode () the first electron beam (a) generates a first focal spot () and the second electron beam () generates a second focal spot (). The X-ray tube () further comprises a common deflection unit (), which is adapted to deflect the first () and the second electron beam (), such that the positions of the first () and the second focal spot () is shifted. The electron sources () may be arranged within a linear array allowing for a simple mechanical support of the X-ray sources.
