Answer 1

Spatial resolution in imaging systems can be improved by using thin slice thicknesses and small detector sizes. Large pixel sizes would result in a coarser image with fewer details, hence do not contribute to improved spatial resolution.

Step-by-step explanation:

The question relates to how spatial resolution can be improved in imaging systems such as cameras or telescopes that use charge-coupled devices (CCDs). Spatial resolution is the ability of an imaging system to distinguish fine details and textures of an object. To enhance spatial resolution, selecting thinner slice thicknesses can help. Thin slice thicknesses enable the system to capture more detailed information and reduce the amount of overlap between slices, leading to clearer images.

Using a matrix with small pixel sizes also contributes to improved spatial resolution, because smaller pixels can capture finer details compared to larger pixels. However, a matrix with large pixel sizes, as mentioned in option b), would not improve resolution; large pixels would result in a coarser image with fewer details. Moreover, small detector sizes can benefit spatial resolution, as they will have less area to capture the incoming light, thereby generating a higher resolution image by capturing more precise light intensity and position measurements.

Given these considerations, the correct answer to the question is e) thin slice thicknesses (1) and small detector sizes (3).
