What types of problems can occur due to technical factors in radiologic imaging?

Technical factors in radiologic imaging significantly influence the quality of the images produced, affecting both photographic and geometric attributes.

Photographic problems pertain to the visibility of details in the image. This can include issues like insufficient exposure, resulting in images that are too dark or too light, which hinders the ability to accurately assess the anatomical structures. Contrast, which affects the differentiation between areas of varying density, is also classified as a photographic problem. If the exposure is not calibrated correctly, it can lead to images that lack the necessary contrast to distinguish between tissues or pathologies.

Geometric problems relate to the spatial accuracy and representation of the anatomical structures. Distortion can occur if the x-ray beam is not perpendicular to the object being imaged, affecting the true representation of the size and shape of the structures. Additionally, issues such as motion blur, due to patient movement or improper timing of exposure, also fall into this category. These factors can compromise the measurement of anatomical distances and angles, which is vital for diagnosis.

Calibration, while crucial, is not classified solely as a type of problem; it is a process to ensure that technical factors are set correctly to avoid the aforementioned photographic and geometric issues. Thus, recognizing that both photographic and geometric problems can arise
