Study Notes
Limitations of Film-Based Radiography
- Superimposition of all structures on the film makes it difficult and sometimes impossible to distinguish a particular detail, especially when structures differ only slightly in density.
- This limitation is particularly challenging when observing some tumors and their surrounding tissues, which often have similar densities.
- Radiography is a qualitative rather than quantitative process, making it difficult to accurately assess the characteristics of an object.
- It is challenging to distinguish between a homogeneous object of nonuniform thickness and a heterogeneous object (including bone, soft tissue, and air) of uniform thickness.
