A pa axial oblique cervical projection demonstrates closed intervertebral disk spaces and distorted vertebral bodies when the central ray angulation is correct.
Digital radiography (DR), an improved type of x-ray inspection, produces an instantaneous digital radiographic image. By using x-ray-sensitive plates to record data as an object is being studied, this technique avoids the need for an intermediary cassette and allows data to be sent instantly to a computer. The incident x-ray radiation is converted into an equivalent electric charge and, ultimately, into a digital image by the employment of a detection sensor. Compared to traditional imaging systems, digital detector arrays (DDAs), sometimes referred to as flat panel detectors, produce digital images of superior quality. Due to their increased dynamic range and signal-to-noise ratio, they could provide radiography applications with improved sensitivity.
