Systems and methods for controlling an x-ray tube filament

A method for preheating a filament of an X-ray tube, comprising:

• obtaining a first emission plan and a second emission plan;
• determining, based on the first emission plan and the second emission plan, a filament temperature, the filament temperature being a result of a previous emission corresponding to the first emission plan;
• obtaining at least one of a value of a tube voltage, a value of a tube current, or a time length for performing a filament preheating plan corresponding to the second emission plan;
• determining, based on the filament temperature, and at least one of the value of the tube voltage, the value of the tube current, or the time length, the filament preheating plan corresponding to the second emission plan;
• and
• performing, based on the filament preheating plan, a filament-preheating operation.

A system for preheating a filament of an X-ray tube, comprising:

• a storage device storing a set of instructions;
• and
• one or more processors configured to communicate with the storage device, wherein when executing the set of instructions, the one or more processors are configured to cause the system to:
• obtaining a first emission plan and a second emission plan;
• determining, based on the first emission plan and the second emission plan, a filament temperature, the filament temperature being a result of a previous emission corresponding to the first emission plan;
• obtaining at least one of a value of a tube voltage, a value of a tube current, or a time length for performing a filament preheating plan corresponding to the second emission plan;
• determining, based on the filament temperature and at least one of the value of the tube voltage, the value of the tube current, or the time length, the filament preheating plan corresponding to the second emission plan;
• and
• performing, based on the filament preheating plan, a filament-preheating operation.
