The Kodak SP136 / 18 × 24 cm DirectView CR Cassette with a GP Storage Phosphor Screen is a consumable imaging component used in computed radiography systems. In essence, it is a cassette containing a phosphor storage screen that captures and retains the latent X-ray image after exposure. The cassette allows radiographic exposures using standard X-ray techniques; after exposure, the cassette is placed into a CR reader, which stimulates the phosphor and converts the stored energy to a digital image. The GP (General Purpose) designation implies a balance between sensitivity, resolution, and image uniformity, suitable for general radiographic applications rather than extreme resolution or specialized uses.

In practical use, an 18 × 24 cm cassette is relatively compact and is suited for imaging smaller anatomical regions (e.g., extremities, small parts, pediatric use) or where a smaller field of view is sufficient. Its size helps reduce unnecessary exposure to adjacent anatomy and may allow more frequent positioning flexibility. The cassette's construction, shells, and screen must maintain precise alignment, flatness, and light shielding so that the stored image is not degraded by ambient light or mechanical stress. Good screening against light leakage and mechanical robustness is important since any warping, bending, or damage can cause image artifacts or registration errors during readout.

Over time, the phosphor screen’s performance degrades (due to repeated exposure, handling wear, or surface damage). As a result, many imaging service professionals monitor the cassette for fading, ghosting, scratches, or reduced sensitivity, and replace or refurbish when necessary. In the context of equipment servicing or replacement markets, the SP136 / 18 × 24 variant is often encountered as a used or refurbished part, sometimes paired with newer screen types (e.g. PQ) when upgrading or refurbishing CR cassettes. Ensuring that the cassette is clean, its shell intact, and that its screen and protective layers are intact are key to maintaining consistent image quality over time.
