What is an algorithm?

• A. A data archiving method
• B. A problem-solving procedure carried out repeatedly by computers
• C. A type of imaging modality
• D. A storage technique

Answer: (B)

An algorithm is a finite, well-defined sequence of instructions that takes input, performs a series of operations, and produces an output to solve a problem. It’s the exact recipe a computer follows to work through a task, step by step, in a predictable way. In OCT, algorithms are used to process raw data into meaningful results—things like filtering noise, correcting phase, segmenting retinal layers, or converting interferometric signals into depth profiles. The defining idea is that the steps are specified and ordered so the same input leads to the same result when the algorithm is applied. This description fits best because it emphasizes solving a problem through a clear, executable procedure carried out by computers. The other options describe data storage, archiving, or imaging methods, which are about handling or capturing information rather than providing a step-by-step method to arrive at a solution.
