Which three detector configurations have the same total beam coverage?

To determine which detector configurations have the same total beam coverage, it’s important to calculate the total coverage for each configuration by multiplying the detector width by the number of rows.

In the case of configuration B (1 mm x 16 rows), the total beam coverage is calculated as follows:

1 mm (width) x 16 (rows) = 16 mm total beam coverage.

For the other configurations:

• The first configuration (0.5 mm x 10 rows) results in 0.5 mm x 10 = 5 mm of coverage.

• The third configuration (2 mm x 8 rows) gives 2 mm x 8 = 16 mm of coverage.

• The fourth configuration (4 mm x 4 rows) calculates to 4 mm x 4 = 16 mm of coverage.

Thus, configurations B, C, and D culminate in the same total beam coverage of 16 mm. However, since the question requires identifying the configurations that share the same total beam coverage, configuration B is indeed one of the options but isn't the only one. The mistake here could have stemmed from misunderstanding the question's focus on identifying unique configurations or overlooking others that matched the coverage mathematically.

Therefore, the correct answer
