Abstract
The present disclosure relates to a PET image scanning method and system. The system may obtain a first PET scanned image and determine at least one first abnormal point of a scanned object in the first PET scanned image. The first PET scanned image is obtained by the PET scanner by performing a first PET scanning on the scanned object. The system may recommend a scanning protocol based on the at least one first abnormal point and control the PET scanner to perform a second PET scanning on the scanned object based on the scanning protocol to obtain a second PET scanned image, and the second PET scanning is a scanning for the at least one first abnormal point.
Claims20
A system, comprising:
- a PET scanner;
- at least one storage device including a set of instructions;
- and
- at least one processor in communication with the at least one storage device, wherein when executing the set of instructions, the at least one processor causes the system to perform operations including:
- obtaining, by the at least one processor, a first PET scanned image, wherein the first PET scanned image is obtained by the PET scanner by performing a first PET scanning on a scanned object;
- determining, by the at least one processor, at least one first abnormal point of the scanned object in the first PET scanned image;
- recommending, by the at least one processor, a scanning protocol based on the at least one first abnormal point;
- and
- controlling, by the at least one processor, the PET scanner to perform a second PET scanning on the scanned object based on the scanning protocol to obtain a second PET scanned image, the second PET scanning being a scanning for the at least one first abnormal point, wherein
- a second scanning range of the second PET scanning covers the at least one first abnormal point and is less than a first scanning range of the first PET scanning, or
- a second reconstruction field of view (RFOV) of the second PET scanned image is less than a first RFOV of the first PET scanned image.

A system, comprising:
- a PET scanner;
- at least one storage device including a set of instructions;
- and
- at least one processor in communication with the at least one storage device, wherein when executing the set of instructions, the at least one processor causes the system to perform operations including:
- positioning, by the at least one processor, a scanned object in a scanning region of the PET scanner;
- causing, by the at least one processor, the PET scanner to perform a first PET scanning on the scanned object to obtain a first PET scanned image, wherein the scanned object remains stationary during the first PET scanning;
- determining, by the at least one processor, at least one first abnormal point of the scanned object in the first PET scanned image;
- and
- causing, by the at least one processor, the PET scanner to perform a second PET scanning on the scanned object to obtain a second PET scanned image, wherein
- a second scanning range of the second PET scanning covers the at least one first abnormal point and is less than a first scanning range of the first PET scanning, or
- a second RFOV of the second PET scanned image is less than a first RFOV of the first PET scanned image.

A system, comprising:
- a CT scanner;
- a PET scanner;
- at least one storage device including a set of instructions;
- and
- at least one processor in communication with the at least one storage device, wherein when executing the set of instructions, the at least one processor causes the system to perform operations including:
- causing, by the at least one processor, the CT scanner to perform a CT scanning on a scanned object to collect a CT image;
- positioning, by the at least one processor, the scanned object in a scanning region of the PET scanner;
- causing, by the at least one processor, the PET scanner to perform a first PET scanning on the scanned object to collect first PET scanning data;
- reconstructing, by the at least one processor, the first PET scanning data to obtain a first PET scanned image;
- determining, by the at least one processor, at least one first abnormal point of the scanned object in the first PET scanned image;
- causing, by the at least one processor, the PET scanner to perform a second PET scanning on the scanned object based on the at least one first abnormal point to obtain a second PET scanned image;
- and
- simultaneously displaying, by the at least one processor, at least two of the CT image, the first PET scanned image, the second PET scanned image, and a fused image of the CT image and the second PET scanned image, wherein
- a second scanning range of the second PET scanning covers the at least one first abnormal point and is less than a first scanning range of the first PET scanning, or
- a second RFOV of the second PET scanned image is less than a first RFOV of the first PET scanned image.
