(Constitution Revised October 13, 2017, May 28, 2019, September 2022)


With the increasing applications of ultrasound techniques in biological and medical research and practice, National and International Ultrasound Societies have been organized in various parts of the world to promote cooperative effort in these areas. In order to integrate this effort further and expand the cooperation on an international basis, a world federation of Affiliated Organizations was indicated. In accordance with this principle and with the decision of the constituent assembly meeting in Vienna, Austria, in June 1969, there is hereby organized an international non‐profit scientific organization which shall be a federation under the following Constitution.

The name of this organization shall be the World Federation for Ultrasound in Medicine and Biology, Inc. (WFUMB).


The headquarters of WFUMB shall be as designated by the Administrative Council.

The objectives of WFUMB shall be scientific, literary, and educational. Its aims shall be to encourage research in the field; to promote international cooperation in the field; and to disseminate scientific information. In pursuit of these aims, WFUMB may, in relation to its specific field of interest, engage in the following activities: sponsorship of meetings; publication of an official journal and other official documents including guidelines and position papers; cooperation with other societies and organizations in training and research projects; appointment of committees and commissions on special problems; and awarding of prizes and distinctions. It may promote the formation of national or regional societies or groups, the coordination of bibliographic and informational services and the improvement of standards in terminology, equipment, methods, training, clinical applications including quality of care and safety practices, and generally shall promote improved communication and understanding in the world community using ultrasound in medicine and biology.

WFUMB is an independent, voluntary, not for profit, medical federation of societies committed to the highest standards of governance, accountability, and responsibility. WFUMB implements fair and transparent decision-making, nomination, and election processes and commits itself to disclose and consider possible conflicts of interest in nominations, elections, and decisions. In the practical implementation of its objectives, WFUMB respects the diversity of its members including professional, national, ethnic, cultural and gender backgrounds.

4.1.      WFUMB membership shall be composed of primarily Affiliated Organizations that have a major interest in the field of medical and biological ultrasound and whose objectives, ethical policy and scientific stature are in keeping with the aims of WFUMB. These organizations may be scientific societies or subgroups thereof or other regional or national bodies as specified in 4.2, 4.3.1 and 4.3.2 below. Individuals who are members of such Affiliated Organizations shall be known as Affiliates of WFUMB.

4.2.      Organizations desiring affiliation must present evidence that they are carrying on one or more of the following activities in an area relevant to the use of ultrasound in medicine and biology: holding regular meetings; publishing a journal of good scientific standard; publishing guidelines; promoting education in ultrasound; maintaining study groups on particular topics. Such an organization must be on a non‐profit basis and maintain high ethical standards; and must have a constitution or other formal documentation of its organization and operation.

4.3.1.    Wherever such an arrangement is practical, several such national groups shall jointly apply for affiliation as a federation based on geographical, linguistic or other common factors. In addition, individual societies that are now members will be encouraged to form regional federations. Normally, and except by a resolution of the General Assembly with respect to a particular situation, not more than one national or regional organization covering the same geographical area may become affiliated.

4.3.2.    Not more than one international specialty organization may become affiliated for any specialty. Such a specialty organization must demonstrate broad representation within such a specialty.

4.4.      Applications for affiliation to WFUMB must be made to WFUMB using procedures specified in the bylaws. If an application is approved by the Administrative Council, it shall then be presented to the General Assembly for approval.

4.4.1.    Membership of organizations approved for affiliation by the General Assembly shall be regarded as provisional for two years and confirmed in the absence of a claim for recognition by other societies seeking to represent the same country or region during this period. During this provisional period, the Affiliated Organization will have all the privileges and responsibilities of membership, subject to the payment of the membership fees. If a rival claim is made, this will be reported on by the Administrative Council, and affiliation shall then be decided by vote of the General Assembly.

4.5       Individual membership in WFUMB shall be through one class of membership: Honorary Life Members.

4.5.1     Individuals who have rendered uniquely valuable service to WFUMB may have bestowed upon them the title of Honorary Life Member. Affiliated Organizations may propose individuals with a current CV and supporting citation letter of recommendation to the Executive Board for consideration.

8.12.2. This information is to be used in the following way to determine the minimum guaranteed surplus to the host organization:

(a) If paid attendance and the number of commercial booth spaces at the joint conference are the same or more than the attendance and booth space average of the host organization’s annual meeting for the four year period prior to the joint conference, the minimum guaranteed surplus for the host organization will be as described in 8.12.la above. (b) If paid attendance and the number of commercial booth spaces at the joint conference are less than the attendance and booth space average of the host organization’s annual meeting for the four year period prior to the joint conference, there shall be a decrease in the level of the guaranteed surplus to the host organization to be determined in the following way:
