Digital motion X-ray
(Digital Motion X-Ray: Non-fluoroscopic) Conventional radiography is now used for the recording of motion studies. This method does not employ the use of fluoroscopy that has been the most common use of X-rays but rather uses conventional X-rays. The manner of recording a motion study is to couple an X-ray system with a digital computer and a detection system that records images in real time.
Example: The A2D2, Inc. Model 1713 is a digital system that is capable of recording static images or a dynamic sequence.
Static images are recorded in a 5,000 by 4,000 pixel array with 14 bit capacity. These images are stored in the computer memory for recording and/or playback. Dynamic studies are recorded in real time at a rate of 30 frames per second with resolution of 1990 by 1200 pixels. Typically, one second of data recording is required for a complete motion study at 30 frames per second. Sophisticated software is used to automatically record the study and then to cause it to playback in a bi-directional format.
Patient radiation dose is minimal over the one second time frame. Typical radiation dose is approximately 2 mSv for this one second period. Any form of joint motion can be recorded and analyzed.
