Why is it important for x-ray cassettes to be rigid?

X-ray cassettes need to be rigid primarily to prevent bending and ensure reuse. A rigid structure helps maintain the integrity of the cassette during the imaging process, which is crucial for obtaining high-quality images. If a cassette is flexible or bendable, it can lead to film placement issues, misalignment, or unnecessary artifacts on the x-ray image. This rigidity ensures that the film remains flat and correctly positioned against the imaging plate, providing consistent and accurate results each time it is used.

Additionally, the durability that comes from a rigid construction allows the cassette to withstand the conditions of frequent handling and repeated use, contributing to cost-effectiveness in a clinical setting. This builds the overall reliability of the imaging process in radiology practices.
