Embodiment

[0028] The technical solution of the present invention is a small animal multimodal medical image registration and image fusion system, which can realize image fusion of two or more medical imaging devices. In this example, a representative small animal PET / CT image fusion is selected as an example. The specific implementation scheme can be divided into the design of the small animal bed, the experimental operation process, the image fusion algorithm and the fusion image display method.

[0029] The fixing scheme of the small animal bed on the stage is as follows: figure 1 . The stage is made of carbon fiber material (length 900mm, arc R59), the stage can easily move freely between small animal PET and small animal CT. There are two threaded holes on the bottom of the small animal bed, which can be fixed with the bottom of the stage. Two metal clips are also used to further ensure the relative stability between the small animal bed and the stage.

[0030] The design scheme...

Abstract

The invention discloses a small animal multi-modal medical image registration and fusion system. The system includes a small animal bed used for transmission between two or more medical imaging devices, and is characterized in that a device for simultaneous imaging of multiple medical imaging devices is provided outside the small animal bed; the system also includes a software-based The automatic registration and fusion of images is characterized by the use of a fusion method based on spatial point rigid body registration. This system can realize the registration and fusion of multi-modal medical images of small animals, and provide richer information for images collected by independent medical imaging equipment.

Description

technical field [0001] The invention belongs to the technical field of image registration and fusion of multimodal medical equipment, and in particular relates to an independent clinical or experimental small animal multimodal medical image registration and image fusion system. Background technique [0002] At present, multimodal medical imaging is mainly used in clinical work for diseases such as tumors, cardiovascular system, and nervous system. In the process of scientists' understanding and research of a certain disease, the establishment of animal models is very important for understanding disease-related diseases. The pathogenesis, evolution process, and new drug development and efficacy monitoring in the therapeutic field all play an irreplaceable role. Therefore, the research of multimodal medical imaging in the field of small animals is also gradually carried out. [0003] However, dedicated small animal multi-modal medical imaging equipment is expensive, and it is ...
