Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0038] Application overview

[0039] The pathological diagnosis of the lesion tissue plays an important guiding role in the judgment of the disease. Clinically, puncture surgery is usually performed under the guidance of lung CT (Computed Tomography, electronic computer tomography) images to obtain pathological specimens for the diagnosis of lesions. In puncture surgery, doctors need to determine the target lesion and puncture path.

Abstract

The invention discloses an image registration method and device, a training method and device, and a control method and device. The image registration method comprises the following steps: acquiring a segmentation result of a marker on a medical image and the position of a key point on the marker; according to the position of the key point on the marker and the position of the corresponding key point of standard segmentation, achieving the translation transformation of the marker, wherein the physical shapes of the marker and the standard segmentation are the same; inputting the segmentation result of the marker on the medical image into a registration model for rotation transformation, so that the segmentation result of the marker and the standard segmentation are registered, and accurate and rapid registration between an organ model formed after medical image modeling and a navigation device where a puncture needle is located can be achieved; therefore, incomplete correspondence between the puncture path of the puncture needle and the puncture path of the virtual puncture needle on the organ model is avoided.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image registration method and device, a training method and device, and a control method and device. Background technique [0002] In puncture surgery, doctors need to determine the target lesion and puncture path. When determining the target lesion and puncture path, it is usually possible to link the organ model on the computer with the navigation device where the puncture needle is located to generate a virtual puncture needle in the organ model on the computer for doctors to view the target lesion and puncture path. However, when the organ model on the computer is linked with the navigation device where the puncture needle is located, the accuracy and speed are often insufficient, resulting in the incomplete correspondence between the puncture path of the puncture needle and the puncture path of the virtual puncture needle.
