Abstract
The present disclosure relates to a method and system for reducing radiation dose in image acquisition. The method may include obtaining first image data of a subject related to a first scan of the subject. The first scan may be of a first type of scan. The method may include reconstructing a first image of the subject based on the first image data and generating a dose plan of a second scan based on the first image. The second scan may be of a second type of scan. The method may also include obtaining second image data of the subject related to the second scan of the subject. The second scan may be performed according to the dose plan.
Claims19
A method implemented on a computing device including a processor and a storage medium, the method comprising:
- determining a count rate distribution in a subject based on first data collected in a third scan of the subject, wherein the third scan is a positron emission tomography (PET) scan, and the first data includes PET data;
- generating a dose plan of a first scan based on the count rate distribution, the first scan being of a first type of scan, wherein the first type of scan is a computed tomography scan, and the dose plan relates to a radiation dose to be delivered to the subject during the first scan;
- obtaining second data of the subject related to the first scan of the subject, the first scan being performed according to the dose plan;
- obtaining third data of the subject related to a second scan of the subject, wherein the second scan is of a second type of scan different from the first type of scan, the second type of scan is a PET scan, and the third data includes PET data;
- and
- generating a target image based on the second data and the third data.
A system, comprising:
- at least one storage device storing a set of instructions;
- and
- at least one processor configured to communicate with the at least one storage device, wherein when executing the set of instructions, the at least one processor is configured to direct the system to perform operations including:
- determining a count rate distribution in a subject based on first data collected in a third scan of the subject, wherein the third scan is a positron emission tomography (PET) scan, and the first data includes PET data;
- generating a dose plan based on the count rate distribution, the first scan being of a first type of scan, wherein the first type of scan is a computed tomography scan, and the dose plan relates to a radiation dose to be delivered to the subject during the first scan;
- obtaining second data of the subject related to the first scan of the subject, the first scan being performed according to the dose plan;
- obtaining third data of the subject related to a second scan of the subject, wherein the second scan is of a second type of scan different from the first type of scan, the second type of scan is a PET scan, and the third data includes PET data;
- and
- generating a target image based on the second data and the third data.
A method, implemented on a computing device having at least one processor and at least one storage device, the method comprising:
- obtaining surface information of a subject collected by an optical camera, wherein the surface information includes a 3D optical image of the subject;
- identifying body parts of the subject from the 3D optical image of the subject;
- generating a dose plan of a first scan by determining doses corresponding to the body parts of the subject, the first scan being of a first type of scan, wherein the first type of scan is a computed tomography scan, the dose plan relates to a radiation dose to be delivered to the subject during the first scan, and different body parts of the subject have different doses;
- obtaining second data of the subject related to the first scan of the subject, the first scan being performed according to the dose plan;
- obtaining third data of the subject related to a second scan of the subject, wherein the second scan is of a second type of scan different from the first type of scan;
- and
- generating a target image based on the second data and the third data.
