Multi-sequence scanning methods and apparatuses, devices and ct systems

An electronic device, comprising:

• at least one processor;
• and
• one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
• in response to a parameter configuration command, configuring scan sequence parameters for a plurality of scan sequences in a scan protocol to obtain a target scan protocol, wherein the scan sequence parameters comprise a scan start time and a scan duration of each of the scan sequences, and a scan switching duration between the scan sequences, wherein a total scan duration of the scan sequences in the target scan protocol is configured to be less than or equal to a preset total scan duration, and wherein the scan switching duration between the scan sequences is configured in a shortest duration mode;
• and
• in response to receiving a scan command, controlling the CT system to scan a scanned object according to the scan sequence parameters configured in the target scan protocol.

A CT system, comprising:

• a ray source, a detector and an electronic device, wherein
• the ray source is configured to emit rays;
• the detector is configured to detect an attenuated ray signal after the rays pass through a scanned object, convert the attenuated ray signal into an electrical signal, and send the electrical signal to the electronic device;
• and
• the electronic device is configured to:
• in response to a parameter configuration command, configure scan sequence parameters for a plurality of scan sequences in a scan protocol to obtain a target scan protocol, wherein the scan sequence parameters comprise a scan start time and a scan duration of each of the scan sequences, and a scan switching duration between the scan sequences, wherein a total scan duration of the scan sequences in the target scan protocol is configured to be less than or equal to a preset total scan duration, and wherein the scan switching duration between the scan sequences is configured in a shortest duration mode;
• and
• in response to receiving a scan command, control the CT system to scan the scanned object according to the scan sequence parameters configured in the target scan protocol.
