Embodiment 1

[0034] Please refer to figure 1 , which is a flow chart of the medical image display method in this embodiment, the medical image display method and device mainly include the following steps:

[0035] First, step S10 is executed to obtain scan data of multiple phases in the cardiac cycle of the subject;

[0036] Preferably, MDCT is used to scan to obtain scan data of multiple phases in the cardiac cycle of the subject. Specifically, the ways of using MDCT to scan and collect data include but are not limited to the following two ways: MDCT adopts electrocardiogram (EGC) gated retrospective spiral acquisition mode for data acquisition or MDCT adopts electrocardiogram (EGC)-triggered gated acquisition mode for data acquisition. data collection.

[0037] Next, step S11 is executed to reconstruct the first images of the multiple time phases based on the scan data;

[0038] Next, step S12 is executed to receive the first display parameters set by the user based on the first image...

Embodiment 2

[0062] Please refer to figure 2 , which is a schematic structural diagram of the medical image display device in this embodiment. Such as figure 2 As shown, the medical image display device includes: a scan data acquisition module, a first image reconstruction module, a first segmented image acquisition module, a second segmented image acquisition module and a phase position display module; the scan data acquisition module is used to obtain the subject The scan data of multiple time phases in the examiner's cardiac cycle; the first image reconstruction module is used to reconstruct the first images of the multiple time phases based on the scan data; the first segmented image acquisition module is used to receive The first display parameter set by the user based on the first image, and based on the first display parameter, the first image is segmented and the first segmented image is displayed; the second segmented image acquisition module is used to receive Reconstructing ...

Abstract

The invention provides a medical image display method and device. The medical image display method comprises the following steps of: obtaining multi-time-phase canning data of an examined person in a cardiac cycle; re-establishing a first multi-time-phase image based on the scanning data; receiving a first display parameter set by a user based on the first image; based on the first display parameter, segmenting the first image, and displaying a first segmented image after segmentation; receiving a second display parameter set by the user based on the first segmented image; re-establishing a second multi-time-phase image based on the second display parameter, and segmenting the second image to obtain a second segmented image after segmentation; and, counting image features based on the second segmented image, and highlighting the time phase position corresponding to the image according with specific features. On the basis of the medical image display method provided by the invention, multi-time-phase data and a three-dimensional MPR image of the examined person can be automatically re-established according to evaluation requirements of doctors; and thus, manual re-establishing of users and the heavy and complicated multi-time-phase image adjusting workload can be avoided.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a medical image display method and device. Background technique [0002] Transcatheter aortic valve implantation (TAVI) is a new minimally invasive valve replacement surgery developed in recent years. Before performing TAVI, it is necessary to conduct an accurate preoperative assessment of the patient's aortic valve annulus, valve condition, and other cardiovascular structures, and then select the replacement artificial valve and surgical plan according to the assessment results. [0003] Multi-detector-row CT (MDCT) is an important imaging method for preoperative evaluation of TAVI. MDCT imaging has high temporal and spatial resolution and can clearly display the aorta and other cardiovascular structures. The characteristics of a three-dimensional multi-planar reformation (MPR) image can be reconstructed. [0004] The evaluation results of the object based on the size evaluat...
