In a lateral projection of the cervicothoracic region, how is the patient's midsagittal plane oriented relative to the image receptor?

In a lateral projection of the cervicothoracic region, the patient's midsagittal plane must be oriented parallel to the image receptor (IR). This orientation ensures that the anatomical structures are properly aligned and captured without distortion on the radiographic image. When the midsagittal plane is parallel to the IR, it allows for an accurate representation of the cervicothoracic region, which is crucial for diagnosing any conditions occurring in that area.

Maintaining this parallel alignment helps to minimize artifacts that can result from angling or mispositioning. This is particularly important in lateral projections, where the visualization of overlapping structures is necessary. Thus, the alignment of the midsagittal plane parallel to the IR directly influences the quality and accuracy of the radiographic assessment.
