Anatomical Regions
Computer reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation
Single plane or bi-plane real time display of an image developed from the capture of external ionizing radiation on a fluorescent screen. The image may also be stored by either digital or analog means
Computer reformatted digital display of multiplanar images developed from the capture of radiofrequency signals emitted by nuclei in a body site excited within a magnetic field
Other specified modality for visualizing a body part
Planar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate
Real time display of images of anatomy or flow information developed from the capture of reflected and attenuated high frequency sound waves
