Abstract

The present disclosure relates to systems and methods for configuring a medical device for a medical procedure. The systems may perform the methods to initialize a gantry angle of a medical device of a new scan. The systems may also perform the methods to obtain a pre-set gantry angle associated with the new scan. The systems may also perform the methods to determine whether the initialized gantry angle is consistent with the pre-set gantry angle. The systems may also perform the methods to adjust the initialized gantry angle of the medical device to the pre-set gantry angle in response to a determination that the initialized gantry angle is inconsistent with the pre-set gantry angle.

First claim

We claim:

1. A system for configuring a medical device for a medical procedure comprising:
one or more storage media comprising a set of instructions; and
one or more processors configured to communicate with the one or more storage media, wherein when executing the set of instructions, the one or more processors are configured to cause the system to:
before performing a new scan on a target object, initialize a gantry angle of the medical device of the new scan based on one or more prior gantry angle values selected by the system; comprising:
acquiring the one or more prior gantry angle values of the medical device;
dividing the one or more prior gantry angle values into one or more groups based on size of the one or more prior gantry angle values;
for each of the one or more groups, determining a number of prior gantry angle values of the group;
selecting, from the one or more groups, at least one group of which the number of prior gantry angle values is maximum among the one or more groups; and
determining that a number of the selected at least one group is more than one and then either
obtaining a prior time instant corresponding to each of the prior gantry angle values in the selected at least one group in response to the determination, determining one of the prior pantry angle values in the selected at least one group with the prior time instant closest to a current time, and initializing the gantry angle of the medical device to the one of the prior gantry angle values in the selected at least one group with the prior time instant closest to the current time; or
determining an average value of the prior gantry angle values corresponding to the selected at least one group in response to the determination; and initializing the gantry angle of the medical device to the average value of the prior gantry angle values corresponding to the selected at least one group.

2. The system of claim 1 , wherein
the one or more prior gantry angle values corresponds to one or more prior scans performed prior to the current time.

3. The system of claim 1 , the one or more processors are further configured to cause the system to:
before initializing the gantry angle of the medical device of the new scan, determine that a prior scan performed closest to the current time has been completed by the medical device.

4. The system of claim 1 , the one or more processors are further configured to cause the system to:
obtain a pre-set gantry angle associated with the new scan;
determine whether the initialized gantry angle is inconsistent with the pre-set gantry angle; and
adjust the initialized gantry angle of the medical device to the pre-set gantry angle in response to a determination that the initialized gantry angle is inconsistent with the pre-set gantry angle.

5. The system of claim 4 , wherein the one or more processors are further configured to cause the system to obtain the pre-set gantry angle based on a scan protocol.

6. The system of claim 1 , wherein the one or more processors are further configured to cause the system to initialize the gantry angle based on an input of a user.

7. A method for configuring a medical device for a medical procedure implemented on a computing device having one or more processors and one or more storage media, the method comprising:
before performing a new scan on a target object, initializing a gantry angle of the medical device of the new scan based on one or more prior gantry angle values selected by the computing device; comprising:
acquiring the one or more prior gantry angle values of the medical device:
dividing the one or more prior gantry angle values into one or more groups based on size of the one or more prior gantry angle values;
for each of the one or more groups, determining a number of prior gantry angle values of the group;
selecting, from the one or more groups, at least one group of which the number of prior gantry angle values is maximum among the one or more groups; and
determining that a number of the selected at least one group is more than one and then either
obtaining a prior time instant corresponding to each of the prior gantry angle values in the selected at least one group in response to the determination, determining one of the prior gantry angle values in the selected at least one group with the prior time instant closest to a current time, and initializing the gantry angle of the medical device to the one of the prior gantry angle values in the selected at least one group with the prior time instant closest to the current time; or
determining an average value of the prior gantry angle values corresponding to the selected at least one group in response to the determination; and initializing the gantry angle of the medical device to the average value of the prior gantry angle values corresponding to the selected at least one group.

8. The method of claim 7 , wherein the one or more prior gantry angle values corresponds to one or more prior scans performed prior to the current time.

9. The method of claim 7 , the method further comprising: before initializing the gantry angle of the medical device of the new scan, determine that a prior scan performed closest to the current time has been completed by the medical device.

10. The method of claim 7 , the method further comprising:
obtaining a pre-set gantry angle associated with the new scan;
determining whether the initialized gantry angle is inconsistent with the pre-set gantry angle; and
adjusting the initialized gantry angle of the medical device to the pre-set gantry angle in response to a determination that the initialized gantry angle is inconsistent with the pre-set gantry angle.

11. The method of claim 10 , wherein the method further comprises obtaining the pre-set gantry angle based on a scan protocol.

12. The method of claim 7 , wherein the method further comprises initializing the gantry angle based on an input of a user.

13. A non-transitory computer readable medium of a medical device, the medium comprising executable instructions that, when executed by at least one processor of the medical device, cause the at least one processor to effectuate a method comprising:
before performing a new scan on a target object, initializing a gantry angle of the medical device of the new scan based on one or more prior gantry angle values selected by the at least one processor; comprising:
acquiring the one or more prior gantry angle values of the medical device;
dividing the one or more prior gantry angle values into one or more groups based on size of the one or more prior gantry angle values;
for each of the one or more groups, determining a number of prior gantry angle values of the group;
selecting, from the one or more groups, at least one group of which the number of prior gantry angle values is maximum among the one or more groups; and
determining that a number of the selected at least one group is more than one and then either
obtaining a prior time instant corresponding to each of the prior gantry angle values in the selected at least one group in response to the determination, determining one of the prior gantry angle values in the selected at least one group with the prior time instant closest to a current time, and initializing the gantry angle of the medical device to the one of the prior gantry angle values in the selected at least one group with the prior time instant closest to the current time; or
determining an average value of the prior gantry angle values corresponding to the selected at least one group in response to the determination; and initializing the gantry angle of the medical device to the ave
