Problems solved by technology

[0005] The technical solutions disclosed in patents such as US20010004942 involve judging whether placenta accreta occurs, but do not study the classification; CN104392145A discloses a method for predicting placenta accreta based on hidden Markov model, although the patent can be proposed by building However, none of them proposed a comprehensive and quantitative B-ultrasound evaluation method.

Embodiment 1

[0090] Example 1: Scoring indicators that can be used for placenta accreta typing

[0091] Data from 180 patients with a clinical diagnosis of placenta accreta were analyzed (clinical data were collected and verified by review of medical records). Through difference comparison, analysis and summary, select placental position, placental thickness, retroplacental hypoechoic zone, bladder line, placental lacuna, placental base blood flow, cervical blood sinus, cervical shape and cesarean section history as the predicted and actual The preoperative detection indicators related to the type of placenta accreta, intraoperative bleeding and intraoperative hysterectomy.

Embodiment 2

[0092] Example 2: Establishment of scoring system

[0093] In order to determine the consistency between the scoring index and the actual clinical classification (the clinical classification is judged by the intraoperative findings and / or pathological results). Aiming at the indicators described in Example 1, the clinical data and results of the above 180 patients with different types of placenta accreta were analyzed, and the "ultrasonic scoring scale of placenta accreta type" was established.

Embodiment 3

[0097] Embodiment 3: Detection data image processing

[0098]Image processing of placental position, placental thickness, retroplacental hypoechoic zone, bladder line, placental lacuna, placental basal blood flow, cervical blood sinus, cervical shape and cesarean section history, all algorithms are directly operated on the detection data . In medical image processing, the so-called volume data refers to a two-dimensional or three-dimensional data set composed of several cuboids with the same volume, and each element of it is called a voxel. Volume data is a generalization of the bitmap concept in two-dimensional or three-dimensional space, and two-dimensional or three-dimensional volume data is composed of uniformly distributed voxels.

[0099] Specifically, the present invention adopts the above-mentioned voxel processing method for images of placental position, placental thickness, retroplacental hypoechoic zone, bladder line, placental lacuna, placental base blood flow, ce...

Abstract

The invention relates to a video image reorganization processing method. The method comprises the steps that data collection of placenta position, placenta thickness, retroplacental low echo zone, glandulae vesicales, placenta lacuna, placenta basilar part blood flow, one or more cervix uteri blood sinus, cervix uteri shape and cesarean section history is conducted. In addition, the invention further relates to a video data processing module and a device using the processing module.

Description

technical field [0001] The invention relates to an image recognition processing method and a related non-invasive examination information system, in particular to a preoperative non-invasive examination information system. Background technique [0002] In recent years, under the influence of rising cesarean section rate and other factors, the incidence of placenta accreta is gradually increasing, and the rate of maternal death caused by complications of placenta accreta is also increasing, seriously threatening the lives of pregnant women , The preoperative classification, diagnosis and treatment of placenta accreta have always been a hot and difficult issue in the research of obstetrics and gynecology. [0003] Placenta accreta refers to the invasion of placental villi into the myometrium, reaching or even penetrating the uterine serosa, and in severe cases involving the bladder or even the rectum. Some researchers reported that the incidence rate of placenta accreta was 1...
