Determination of the maximum symmetrical radiation field of X-ray tube assemblies and X-ray source assemblies for medical diagnosis
This International Standard is applicable to X-RAY SOURCE ASSEMBLIES and X-RAY TUBE ASSEMBLIES, for use in MEDICAL DIAGNOSTIC RADIOLOGY for techniques in which the X-RAY PATTERN will be received simultaneously in all points of the IMAGE RECEPTION AREA. This standard specifies a method for the determination of the greatest geometrically symmetrical RADIATION FIELD at a specified distance from the FOCAL SPOT for which the percentage AIR KERMA RATE along the major axes of the RADIATION FIELD does not fall below a permitted value. NOTE 1 AIR KERMA or AIR KERMA RATE are the only practical verifiable physical quantities for X-RAY SOURCES. X-RAY SOURCES must be tested independently from MEDICAL ELECTRICAL SYSTEMS. Conversion to the characteristics of the X-RAY IMAGE RECEPTOR used in a MEDICAL ELECTRICAL SYSTEM may be done in addition. In case multiple FOCAL SPOTS are not super-imposed, each focal spot has its own REFERENCE AXIS. Then the maximum RADIATION FIELD may be given for each FOCAL SPOT separately NOTE 2 The maximum symmetrical RADIATION FIELD may change from its initial value as the X-RAY TUBE ages through use. NOTE 3 If, for certain MEDICAL ELECTRICAL SYSTEMs the scope of IEC 60806 does not fit, then the special RADIATION FIELD requirements could be incorporated in the MEDICAL ELECTRICAL SYSTEM particular standard. However, a statement on the RADIATION FIELD while referring IEC 60806 is then no longer possible.

35 FOREWORD
36 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all
37 national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co -operation
38 on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other
39 activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available
40 Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their prepa ration is entrusted to technical
41 committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work.
42 International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation.
43 IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions
44 determined by agreement between the two organizations.45 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus
46 of opinion on the relevant subjects since each technical committee has representation from all interested IEC National
47 Committees.48 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees
49 in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate,
50 IEC cannot be held responsible for the way in which they are used or for any mi sinterpretation by any end user.
51 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently
52 to the maximum extent possible in their national and regional publications. Any divergence between a ny IEC Publication
53 and the corresponding national or regional publication shall be clearly indicated in the latter.
54 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment
55 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
56 independent certification bodies.57 6) All users should ensure that they have the latest edition of this publication.
58 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members
59 of its technical committees and IEC National Committees for any personal injury, property damage or other damage of
60 any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the
61 publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
62 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable
63 for the correct application of this publication.64 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights.
65 IEC shall not be held responsible for identifying any or all such patent rights.
66 International Standard IEC 60806 has been prepared by subcommittee 62B: Diagnostic imaging
67 equipment, of IEC technical committee Electrical equipment in medical practice.
68 This second edition cancels and replaces the first edition published in 1984 and constitutes a technical
69 revision.70 This edition includes the following significant technical changes with respect to the previous edition:
71 Since 1984, the first edition, considerable developments have been taken place in dete ctor technology.
72 So instead of RADIOGRAPHIC FILM, solid state detectors are generally used; the second edition thus
73 applies such detectors, while keeping the alternative of RADIOGRAPHIC FILM.74 The text of this standard is based on the following documents:

94 DIAGNOSIS
98 1 Scope
99 This International Standard is applicable to X-RAY SOURCE ASSEMBLIES and X-RAY TUBE ASSEMBLIES, for
100 use in MEDICAL DIAGNOSTIC RADIOLOGY for techniques in which the X-RAY PATTERN will be received
101 simultaneously in all points of the IMAGE RECEPTION AREA.102 This standard specifies a method for the determination of the greatest geometrically symmetrical
103 RADIATION FIELD at a specified distance from the FOCAL SPOT for which the percentage AIR KERMA RATE
104 along the major axes of the RADIATION FIELD does not fall below a permitted value.
105 NOTE 1 AIR KERMA or AIR KERMA RATE are the only practical verifiable physical quantities for X-RAY SOURCES. X-RAY SOURCES
106 must be tested independently from MEDICAL ELECTRICAL SYSTEMS. Conversion to the characteristics of the X-RAY IMAGE
107 RECEPTOR used in a MEDICAL ELECTRICAL SYSTEM may be done in addition.108 In case multiple FOCAL SPOTS are not super-imposed, each focal spot has its own REFERENCE AXIS.
109 Then the maximum RADIATION FIELD may be given for each FOCAL SPOT separately110 NOTE 2 The maximum symmetrical RADIATION FIELD may change from its initial value as the X-RAY TUBE ages through use.
111 NOTE 3 If, for certain MEDICAL ELECTRICAL SYSTEMs the scope of IEC 60806 does not fit, then the special RADIATION FIELD
112 requirements could be incorporated in the MEDICAL ELECTRICAL SYSTEM particular standard. However, a statement on the
113 RADIATION FIELD while referring IEC 60806 is then no longer possible.114 2 Normative references
