Abstract
The present disclosure provides a PET data compensation system and method. The method may include obtaining a count of missing data of first coincidence data. The method may also include obtaining second coincidence data and a second count of the second coincidence data, the second coincidence data and the missing data constituting the first coincidence data. The method may further include performing a compensation relating to the second coincidence data based on at least two of the count of the missing data, a first count of the first coincidence data, or the second count of the second coincidence data.
Claims19
A system, comprising:
- at least one storage medium including a set of instructions;
- and
- at least one processor configured to communicate with the at least one storage medium, wherein when executing the set of instructions, the at least one processor is configured to direct the system to perform operations including:
- obtaining a count of missing data of first coincidence data;
- obtaining second coincidence data and a second count of the second coincidence data, the second coincidence data and the missing data constituting the first coincidence data;
- performing a compensation relating to the second coincidence data based on at least two of the count of the missing data, a first count of the first coincidence data, or the second count of the second coincidence data, wherein the performing a compensation relating to the second coincidence data based on at least two of the count of the missing data, a first count of the first coincidence data, or the second count of the second coincidence data includes:
- determining a preliminary Standard Uptake Value (SUV) based on the second coincidence data;
- determining a compensation coefficient based on the at least two of the count of the missing data, the first count of the first coincidence data, or the second count of the second coincidence data;
- generating a compensated SUV by compensating the preliminary SUV using the compensation coefficient;
- and
- compensating the second count of the second coincidence data using the compensation coefficient.
A method implemented on a computing device having a processor and a computer-readable storage device, the method comprising:
- obtaining a count of missing data of first coincidence data;
- obtaining second coincidence data and a second count of the second coincidence data, the second coincidence data and the missing data constituting the first coincidence data;
- performing a compensation relating to the second coincidence data based on at least two of the count of the missing data, a first count of the first coincidence data, or the second count of the second coincidence data, wherein the performing a compensation relating to the second coincidence data based on at least two of the count of the missing data, a first count of the first coincidence data, or the second count of the second coincidence data includes:
- determining a preliminary Standard Uptake Value (SUV) based on the second coincidence data;
- determining a compensation coefficient based on the at least two of the count of the missing data, the first count of the first coincidence data, or the second count of the second coincidence data;
- generating a compensated SUV by compensating the preliminary SUV using the compensation coefficient;
- and
- compensating the second count of the second coincidence data using the compensation coefficient.
A non-transitory readable medium, comprising at least one set of instructions, wherein when executed by at least one processor of a computing device, the at least one set of instructions directs the at least one processor to perform a method, the method comprising:
- obtaining a count of missing data of first coincidence data;
- obtaining second coincidence data and a second count of the second coincidence data, the second coincidence data and the missing data constituting the first coincidence data;
- performing a compensation relating to the second coincidence data based on at least two of the count of the missing data, a first count of the first coincidence data, or the second count of the second coincidence data, wherein the performing a compensation relating to the second coincidence data based on at least two of the count of the missing data, a first count of the first coincidence data, or the second count of the second coincidence data includes:
- determining a preliminary Standard Uptake Value (SUV) based on the second coincidence data;
- determining a compensation coefficient based on the at least two of the count of the missing data, the first count of the first coincidence data, or the second count of the second coincidence data;
- generating a compensated SUV by compensating the preliminary SUV using the compensation coefficient;
- and
- compensating the second count of the second coincidence data using the compensation coefficient.
