Problems solved by technology

This puts forward high requirements for both doctors and patients who use ultrasound fusion imaging navigation. If the patient's breathing control is poor or the doctor has insufficient operating experience, satisfactory results are often not achieved, such as low registration accuracy and poor fusion accuracy. Imaging success rate decreased,
The current method for eliminating the influence of breathing mainly relies on doctors to manually judge the breathing phase or add sensors for simple breathing gating, but the effect is not good.

Embodiment 1

[0026] The block diagram of a typical ultrasound fusion imaging navigation system is as follows: figure 1 As shown (excluding the dotted line box): the ultrasound probe 101 transmits ultrasound to the human body inspection site, and the received echo signal is processed by the ultrasound imaging module 102 to obtain an ultrasound image of the target organ; another modality image data acquired in advance, such as CT or MR images are imported into the registration fusion module 105 before registration; the position sensor 103 fixed on the probe 101 continuously provides position information as the probe moves, and the six-freedom position of the probe is obtained through the positioning controller 104. degree (including vertical, lateral, longitudinal, pitch, roll, and sway) spatial orientation information; the registration fusion module 105 uses image information and position information to register and fuse the ultrasound image and another modality data; the display module 106...

Embodiment 2

[0044] When applying the ultrasound fusion imaging navigation system, usually many patients have relatively poor breathing control ability, and the acquisition and fusion of the registration video are carried out under the condition that the patient breathes freely. However, when the person breathes freely, the organs also Followed by more complex movements, the movement forms include both rigid movements such as translation and rotation, as well as non-rigid movements such as overall or local deformation caused by extrusion between organs. This makes the organ movement caused by breathing have a great impact on the fusion result, so it is necessary to weaken or eliminate the influence of breathing on registration and fusion. Based on this, this embodiment proposes a method for registering and fusing ultrasound images with another pre-acquired modality image. First, based on the ultrasound video and the position and orientation information of the position sensor, a method for d...

Embodiment 3

[0092] A method for fusing an ultrasound image and another pre-acquired modality image provided in this embodiment includes the following steps:

[0093] The playback step is to play or play back at least one section of pre-stored ultrasonic video data frame by frame according to the input playback instruction, the ultrasonic video data includes ultrasonic images obtained by collecting the target object from at least one plane, and corresponding to each frame of ultrasonic images. Position pointing information and respiratory position information, wherein the position pointing information is sensed by the position sensor fixed on the ultrasonic probe during the ultrasonic image acquisition process, and the respiratory position information is obtained by the respiratory sensor fixed on the target object during the ultrasonic image acquisition process Sensing the breathing of the target object;

[0094] In the registration step, multiple frames of ultrasound images are selected ...

Abstract

The present application relates to an ultrasound fusion imaging method and an ultrasound fusion imaging navigation system. The ultrasound fusion imaging method comprises: a selection step, comprising selecting at least one ultrasound image from at least one previously stored piece of ultrasound video data according to an input instruction, wherein the ultrasound video data comprises an ultrasound image obtained by acquiring a target object from at least one plane and location-pointing information corresponding to the ultrasound image; a registration step, comprising registering the selected at least one ultrasound image with a modality image, wherein the registration process uses the location-pointing information of the at least one ultrasound image; and a fusion step, comprising image fusion of the registered ultrasound image with the modality image. The present invention differs from the existing registration-fusion methods based on real-time ultrasound in using a recorded registration video by scanning a target object prior to registration, and then selecting one or more ultrasound images to perform registration.

Description

technical field [0001] The present application relates to ultrasound imaging technology, in particular to a method for fusing an ultrasound image with another pre-acquired modality image, and an ultrasound fusion imaging navigation system. Background technique [0002] More than one imaging system can be used for clinical imaging of target objects, so that medical staff can obtain medical images of various modalities, such as CT (Computed Tomography, computerized tomography) images, MR (Magnetic Resonance, magnetic resonance, etc.) ) images, ultrasound images, etc. The principle of ultrasound fusion imaging navigation is to establish the spatial correspondence between real-time ultrasound images and other modality data (such as CT or MR images) acquired in advance through a spatial positioning device (usually a magnetic positioning sensor bound to the probe). , and superimpose and display the ultrasound with the corresponding data section of another modality to achieve the ...
