a scanning field of view.
3. The method according to claim 1 , wherein the overlapping for the scanning areas of two adjacent scanning sequences comprises at least one of:
a start position of a first scanning sequence being located in a start-stop range of a second scanning sequence immediately before the first scanning sequence; and
a stop position of the first scanning sequence being located in the start-stop range of the second scanning sequence.
4. The method according to claim 1 , wherein determining the target scanning area comprises:
determining a start position and a stop position of the target scanning area according to respective start positions and stop positions of the at least two mergeable scanning sequences.

outputting a message to request a user to agree with a merged scanning with respect to the at least two mergeable scanning sequences;
receiving an operation result from the user in response to the message; and
performing the merged scanning on the target scanning area if the operation result indicates that the user agrees with the merged scanning.
6. The method according to claim 1 , further comprising:
extracting respective scanning data of the mergeable scanning sequences from the scanning data; and
performing an image reconstruction according to a set image reconstructing parameter with the extracted respective scanning data.

a scanning field of view.
9. The device according to claim 7 , wherein the overlapping for the scanning areas of two adjacent scanning sequences comprises at least one of:
a start position of a first scanning sequence is located in a start-stop range of a second scanning sequence immediately before the first scanning sequence; and
a stop position of the first scanning sequence is located in the start-stop range of the second scanning sequence.
10. The device according to claim 7 , wherein when determining the target scanning area, the machine-executable instructions cause the processor to:
determine a start position and a stop position of the target scanning area according to respective start positions and stop positions of the at least two mergeable scanning sequences.
11. The device according to claim 7 , wherein the machine-executable instructions further cause the processor to:
output a message to request a user to agree with a merged scanning with respect to the at least two mergeable scanning sequences;
receive an operation result from the user in response to the message; and
perform the merged scanning on the target scanning area if the operation result indicates that the user agrees with the merged scanning.
