Problems solved by technology

Since the size of the overlapping area between all beds is the same, this leads to a problem that there is no guarantee that each bed can exactly contain the part of interest
Especially when the area for data collection includes both dynamic parts (such as the chest with periodic heartbeat movement) and static parts (such as the head), it can be more efficient if the dynamic parts and static parts are separated for data collection. However, the existing technology cannot well guarantee that the dynamic part and the static part are located in different beds (that is, different beds contain their respective regions of interest)

Abstract

Embodiments of the invention provide an image processing method and device, and relate to the technical field of medical data processing. In the technical solution provided by the embodiment of the invention, each bed can include a part of interest by flexible adjustment of an overlapping region. The method includes: first acquiring a pre-scanned image including a region to be acq1uired; determining a range of the region to be acq1uired in the pre-scanned image; then determining a bed for acquiring the date of the region to be acq1uired; and adjusting the head position and/or the foot positionof each bed according to the position of an organ include in the region to be acq1uired. The technical solution provided by the embodiment of the invention is applicable to the bed position determining process of a medical data acquisition system.

Description

【Technical field】 [0001] The invention relates to the technical field of medical data processing, in particular to an image processing method and device. 【Background technique】 [0002] In the combined system of functional imaging and anatomical imaging, such as PET-MR (Positron Emission Computed Tomography--Magnetic Resonance, Positron Emission Computed Tomography--MRI) system or PET-CT (Positron Emission Computed Tomography, Positron Emission Tomography, -X-ray computed tomography) system collects data in the area to be examined, due to the limitation of the axial collection range of the PET system, when collecting data for the whole body or a larger area, it often needs to be divided into multiple beds for separate collection. And because of the hardware limitation of the PET acquisition detector, the farther the distance from the center of the field of view of the acquisition site is, the worse the data accuracy is. Therefore, in order to ensure the accuracy of the acqui...
