- SHIELDED X-RAY SOURCE METHOD OF SHIELD AN X-RAY SOURCE, AND MAGNETIC SURGICAL SYSTEM WITH SHIELDED X-RAY SOURCE
- This mvention relates to magnetically shielding x-ray sources, and in particular to magnetically shielded x-ray sources, methods of magnetically shielding x-ray sources, and to a magnetic surgical system with a magnetically shielding x-ray source
- a second element of magnetic vulnerability occurs m tubes with rotating metal anodes These anodes can have eddy currents which cause a drag that slows the anode rotation
- the magnetic field levels at which this effect is significant are more variable, depending on field direction and va ⁇ ation in time
- Slow varying fields of 50 Gauss or so do not result in significant effect on the anode rotation
- Another effect is the concentration of field caused by sharp curves m a shield surface, resulting in concentration of flux causing a local high field, and/or saturation of the shield
- a lesser known effect is the geometrical effect of "flux directing" by the shape of the shield
- This effect there is a dependence on the size and distance of the source field relative to the shield
- a relatively close source field can saturate the front of a shield before achieving a high field at the rear If the same source field at the location of the center of the shield were caused by a physically large source, this front-rear discrimination would not occur
- the shape of the shield can be important, and the location of holes should be at the rear (away from the source)
- the present invention relates to a shielded x-ray source, a method of shielding an x-ray source, and a magnetic surgical system with shielded x-ray source
- the shielded x-ray source of the present invention has a cast shield of an iron based material substantially enclosing and closely conforming to the x-ray tube to shield the x-ray tube imaging beam from interference from magnetic fields
- the shield is preferably made of cast iron, but could also be made of cast steel
- the shield is preferably at least 1/4 inch thick Because the shield is cast, it can be inexpensively made to closely conform to the external shape of the x-ray tube There is preferably less than 1/4 inch gap between the x-ray tube and the shield, and more preferably nor more than 1/16 inch gap between the x-ray tube and the shield
- the shield is preferably cast in two or more pieces, which are assembled around the x-ray tube and secured together Such a field can be more efficient than others and therefore significantly lighter for mounting on c-arms and other apparatus Moreover, it will have a smaller magnetic moment and less disturbing force on it than less efficient shields
- the method of the present invention comprises providing a shield cast from an iron- based material in a shape
- the magnetic surgical system comprising at least one magnetic for magnetically navigating a medical device in an operatmg region in a patient's body, and an imaging apparatus including at least one x-ray tube for imaging the operatmg region, the improvement including a cast shield of an iron-based material substantially enclosing and closely conforming to the at least one x-ray tube
- the shield is preferably cast iron, but could also be made of cast steel
- the shield is preferably at least 1/4 inch thick Because the shield is cast, it can be inexpensively made to closely conform to the external shape of the x-ray tube There is preferably less than 1/4 inch gap between the x-ray tube and the shield, and more preferably nor more than 1/16 mch gap between the x-ray tube and the shield
- the shield is preferably cast in two or more pieces, which are assembled around the x-ray tube and secured together
- FIG 1 is an end elevation view of a magnetic surgery system with a magnetically shielded x- ray source m accordance with the principles of this mvention
- Fig 2a is an exploded perspective view of the cast x-ray tube shield and x-ray tube m accordance with the principles of this invention
- Fig 2b is a perspective view of the cast x-ray tube shield installed around an x-ray tube
- Fig 3 A is a drawmg of the field lmes created by a magnet from a magnetic surgery system as they would extend through an unshielded x-ray source
- Fig 3B is a drawing of the field lmes created by a magnet from a magnetic surgery system as they would extend around an x-ray source shielded in accordance with the principles of this invention.
- Fig 4 is a graph showing the relationship between the thickness of the shield verses magnetic field inside the shield
- a magnetic surgery system constructed according to the principles of this invention is indicated generally as 20 in Fig 1
- the magnetic surgery system 20 comprises a patient support 22, a magnet system 24 for generating magnetic fields in an operating region in a patient lying on the patient support, and an imaging system 26 for imaging the operating region in the patient
- the imagmg system 26 comprises a C-arm 28, and two x-ray sources, such as x-ray tubes 30 and two imaging plates, such as amorphous silicon last plates 32, each aligned with one of the x-ray tubes
- the imaging system is thus capable of providing bi-planar imaging of the operatmg region of a patient on the patient support 22
- the imaging system 26 could be of some other design and construction, but would still include at least one x-ray tube 30
- Fig 3 A shows a cross section of the magnetic field lmes from a representative magnet without a permeable material nearby
- Fig 3B shows the same cross-section with a permeable shield m a typical close location to it This illustrates how the field lmes are pulled into the permeable shield material both on the outside (where it is only relevant if it leads to saturation) and on the mside, where it reduces the field seen by an x-ray tube in that region
- Fig 3B illustrates the problem of using an unshielded x-ray tube in the presence of strong magnetic fields, such as those created in the vicinity of the permanent magnets or electromagnets of a magnetic surgery system
- the field lines from a magnet in the magnetic surgery system 20 pass through the x-ray tube 30, potentially interfering with the generation of an x-ray beam
- a shield 34 is cast from a highly magnetically permeable ferrous material, such as a low carbon cast iron, or cast steel Castmg the shield 34 allows the shield to be made in a shape that closely conforms to the exterior of the x-ray tube 30
- the shield 34 is preferably shaped so that the gap between the shield and the x-ray tube is not more that about 1/4 mch, more preferably not more than about 1/16 mch
- the shield is preferably at least 1/4 inch thick As shown Fig 4, m an applied magnetic field of 0 08 T, a thickness of 1/4 mch is sufficient to keep the magnetic field inside the shield to less than about 50 Gauss
- Fig 4 shows the results of iterative calculations which deal with the nonlinea ⁇ ties of magnetization characte ⁇ stics of a shielding material having characteristics common to low carbon steels or cast irons
- the permeability used for these calculations is 1000 and saturation at 13,000 Gauss, which are typical numbers for cast permeable materials
- the results are most sensitive to permeability, but change only marginally for variations in permeability from a few hundred to a few thousand
- the figure also shows curves for three different external fields transverse to the shield surface
- the surface of an infimtely long cylinder represents an effectively closed-end cylinder of ordinary length
- the shield 32 is preferably cast m at least two pieces 36 and 38.
- the shield 34 is installed on the x-ray tube 30 by placing the two pieces 36 and 38 around the x-ray tube and securing them Holes for the electrical and coolmg entrances 40 and 42, respectively, are at the rear of the shield 34, I e , away from the part closest to the source field
- a shield aperture 44 at the front for the x-ray beam exit is designed to have a minimum size which will pass the beam. This has been found experimentally to permit sufficiently small magnetic field penetration, in shield locations where the imagmg c-arm is used.
- a field USS than 50 Gauss is found at the location of the initial part of the electron beam of the generating tube, when a field of 800 Gauss is present without the shield.
- This field is created by a coil of 530,000 ampere turns, of radius 8.5 inches, and located 27 inches from the front center of the shield.
