Abstract

A method and device for multi-sequence scanning are provided. According to an example of the method, when at least two mergeable scanning sequences are obtained from a plurality of scanning sequences, a target scanning area including respective scanning areas of the at least two mergeable scanning sequences may be determined; and then a scanning on the target scanning area may be performed with the at least two mergeable scanning sequences. As at least two scanning sequences satisfying a preset mergeable condition may be extracted from a plurality of scanning sequences, the at least two scanning sequences satisfying the preset mergeable condition may be performed at once.

First claim

The invention claimed is:

1. A method of multi-sequence scanning, comprising:
obtaining at least two scanning sequences satisfying a preset mergeable condition from a plurality of scanning sequences, wherein the preset mergeable condition indicates that the at least two scanning sequences have a same scanning parameter and scanning areas of two adjacent scanning sequences in the at least two scanning sequences are overlapped;
taking the obtained scanning sequences satisfying the preset mergeable condition as at least two mergeable scanning sequences;
determining a target scanning area which comprises respective scanning areas of the at least two mergeable scanning sequences; and
acquiring scanning data by performing a scanning on the target scanning area with the at least two mergeable scanning sequences.

2. The method according to claim 1 , wherein the scanning parameter comprises at least one of:
an X-ray tube voltage value,
an X-ray tube current time product value,
an X-ray beam collimation width,
a ratio of scanning bed moving speed with respect to an X-ray beam collimation width,
a scanning gantry tilt angle, and
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.

5. The method according to claim 1 , further comprising:
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.

7. A device for multi-sequence scanning, comprising:
a processor, and
a machine-readable storage medium to store machine-executable instructions corresponding to control logic for multi-sequence scanning,
wherein, by reading and executing the machine-executable instructions, the processor is caused to:
obtain at least two scanning sequences satisfying a preset mergeable condition from a plurality of scanning sequences, wherein the preset mergeable condition indicates that the at least two scanning sequences have a same scanning parameter and scanning areas of two adjacent scanning sequences in the at least two scanning sequences are overlapped;
take the obtained scanning sequences satisfying the preset mergeable condition as at least two mergeable scanning sequences;
determine a target scanning area which comprises respective scanning areas of the at least two mergeable scanning sequences; and
acquire scanning data by performing a scanning on the target scanning area with the at least two mergeable scanning sequences.

8. The device according to claim 7 , wherein the scanning parameter comprises at least one of:
an X-ray tube voltage value,
an X-ray tube current time product value,
an X-ray beam collimation width,
a ratio of scanning bed moving speed with respect to an X-ray beam collimation width,
a scanning gantry tilt angle, and
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.

12. The device according to claim 7 , wherein the machine-executable instructions further cause the processor to:
extract respective scanning data of the mergeable scanning sequences from the scanning data; and
perform an image reconstruction according to a set image reconstructing parameter with the extracted respective scanning data.

13. A non-volatile machine-readable storage medium having machine-executable instructions executable by one or more processors stored thereon, wherein the machine-executable instructions cause the processor to:
obtain at least two scanning sequences satisfying a preset mergeable condition from a plurality of scanning sequences, wherein the preset mergeable condition indicates that the at least two scanning sequences have a same scanning parameter and scanning areas of two adjacent scanning sequences in the at least two scanning sequences are overlapped;
take the obtained scanning sequences satisfying the preset mergeable condition as at least two mergeable scanning sequences;
determine a target scanning area which comprises respective scanning areas of the at least two mergeable scanning sequences; and
acquire scanning data by performing a scanning on the target scanning area with the at least two mergeable scanning sequences.
