Embodiment Construction

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0029] The present invention is based on the inventor's recognition and discovery of the following problems:

[0030] The development of an MR navigation system consists of three main tasks:

[0031] The first major task is the probe localization technique. In this technique, the physician is concerned with the orientation of the probe and the coordinates of the tip location. Existing probe positioning technologies are mainly divided into passive positioning and active positioning.

[0032] Passive localization technology is b...

Abstract

The invention discloses a magnetic resonance navigation method and device for a microwave thermal ablation operation of a liver, and relates to the technical field of medical instruments and magnetic resonance, and the method comprises the following steps: collecting a magnetic resonance anatomical image of a to-be-ablated area of the liver; identifying a microwave probe image and a lesion image from the anatomical image, and positioning tracking time coordinates of a microwave probe and a lesion according to the microwave probe image and the lesion image; and predicting actual coordinates of the current moment through the tracking moment coordinates of the microwave probe and the lesion, and generating a navigation path of the microwave probe according to the actual coordinates so as to carry out navigation on the microwave probe according to the navigation path. According to the method, real-time and accurate navigation information can be provided for doctors, the requirements of the doctors are met, system delay is effectively overcome, real-time feedback is achieved, and the operation experience of the doctors and patients is improved.

Description

technical field [0001] The invention relates to the technical fields of medical equipment and magnetic resonance, in particular to a magnetic resonance navigation method and device for microwave thermal ablation of the liver. Background technique [0002] During the microwave thermal ablation operation applied to the liver, medical image navigation is the key technology to assist the smooth implementation of the operation. With the guidance of medical images, doctors can determine the relative positional relationship between the probe and the lesion, so that the interventional equipment can enter the target area safely, quickly and accurately, and ensure the safety of vital organs such as the liver. Magnetic resonance imaging has become a potential imaging modality due to its advantages of no ionizing radiation, high tissue resolution, and multi-directional imaging. [0003] The basic process of MRI-guided microwave thermal ablation of the liver includes: before the operati...
