ARRT’s familiar logo has a split personality: on one hand, it’s an intriguing symbol; on the other, it's also a legally protected trademark for use only by our organization.


There’s sound science behind the elements of ARRT’s logo. In the center is an illustration of an X-ray tube and a sine wave. The sine wave represents one cycle of alternating current generated on a one-pole generator through one rotation. Electrical engineers designate the rotation through 360 degrees as being 2 pi, which is the circumference of a circle with a radius of one. Therefore, a one-pole generator would move a distance of 0 to 2 pi in traveling through the circumference of the circle. On the emblem, 0 and 2 pi are placed at the beginning and end of the sine wave.

The energy bolts on each side of the logo represent the high voltage used in the production of X-rays. The atomic symbol at the bottom of the logo represents the primary radiation (radiation produced by the X-ray tube) and secondary radiation (interactions of radiation in the body). The atomic symbol is also relevant to nuclear medicine (with the use of radiopharmaceuticals) and radiation therapy (with the emission of therapeutic radiation.)

Completing the logo are the letters "ARRT," representing The American Registry of Radiologic Technologists.


Restrictions on using the ARRT logo come from both the U.S government and the ARRT Rules and Regulations.

ARRT’s logo is a registered trademark under U.S. Reg. Nos. 0779203 and 1,134,334. Federal and applicable state laws specifically prohibit unauthorized use, which could lead to criminal prosecution and civil damages. We use the logo to indicate that we've issued a particular document. Consequently, there is no such thing as authorization for other uses, and we vigorously refute any attempts of other parties to use our logo. More specific language in the ARRT Rules and Regulations make it clear that we not only own the logo, we also own the documents upon which the logo is printed. 

All R.T.s are subject to the ARRT Rules and Regulations. Failure to conform to their requirements can lead to censure, revocation, and legal action.
