According to the ARRT It is the philosophy of the ARRT that an individual licensed in limited scope radiography possess the same knowledge and cognitive skill, in his or her specific area of radiography, as general radiographers. I am an LXMO and there should be a more bridge programs "advanced placement programs" availble to us. The ASRT and ARRT need to defend us just like the board of nursing does. I went to a 16 moth program to be an LXMO and I think that we shouln't be blocked from being an RT, what most people do not understand is that I costs time and more money as much $20,000 to "start from scratch"

I agree with you, there should be a bridge between LXMO's and RT's we both have the same working knowledge and according to ASRT and ARRT LXMO's are just as competent in performing basic radiographic examinations as RT's are. If there are any other LXMO's interested in signing this petition I am with you.

Distortion - The alteration of the original shape (or other characteristic) of an object, image, sound, waveform or other form of information or representation.

Remember that Contrast and Density are two photographic properties that comprise visibility of detail, well, in addition to Recorded Detail, Distortion is the second of two geometric properties affecting radiographic image quality.

Unlike the photographic properties of density and contrast which control the visibility of detail, the geometric properties control detail itself. Distortion is a misrepresentation of the size or shape of the structure being examined. It creates a misrepresentation of the size and/or shape of the anatomical part being examined. This misrepresentation can be classified as either size or shape distortion.

Distortion, like recorded detail, exists even when it cannot be seen due to poor visibility or, in other words, when the density and/or contrast are poor. The evaluation and adjustment of distortion require a thorough familiarity with normal radiographic anatomy. Unless the normal shape and size of a structure are actually known, comparison of the size and shape cannot be accomplished.

Distortion can be difficult to determine even when normal sizes and shapes are known. Because the objective of radiography is to provide accurate images of structures, methods of minimising distortion are important to diagnosis.
