"The anterior commissure - posterior commissure line (AC-PC line), also known as the bicommissural line, has been adopted as a convenient standard by the neuroimaging community, and in most instances is the reference plane for axial imaging in everyday scanning. The creation of a standard image plane makes it easier to perform comparisons between exams."
"It is described on midline sagittal images and is similar to the orbitomeatal line traditionally used on CT, although the AC-PC line is typically ~9 degrees steeper than the orbitomeatal line 2."
"Prior to widespread volumetric CT brain acquisition which has allowed axial images to be reformatted along the AC-PC line, a number of techniques were developed to approximate the CT gantry tilt such that axial images generated were similar to the AC-PC line. Such methods include:"
