Description
Technical Field
The invention relates to the field of pediatrics, in particular to a full-moon-shaped fetus shape analysis system.
Background
The pre-pregnancy examination refers to the physical examination before the couple is ready to become pregnant, so as to ensure that a healthy baby is born, thereby realizing the prenatal care. The pre-pregnancy examination is different from the conventional physical examination, and mainly aims at the examination of the reproductive system and genetic factors. Both couples and couples do pre-pregnancy check of related items, which is the basic guarantee for the life health of children. The healthy baby must be a crystal in which healthy sperm and ovum are combined, so men should also check it. The optimal time for pre-pregnancy examination is 3-6 months before pregnancy.
If there are obvious hereditary diseases in the family, people pay attention to the examination during the birth and consult with doctors consciously. However, some parents are carriers of a certain genetic disease gene as normal people, and the genetic disease is probably transmitted to the next generation although the parents do not have the disease. For example, a albinism child has the same parents as the normal child, but has the appearance of white skin and pale yellow hair. At present, there are thousands of genetic diseases, and most of them have no root treatment. Once a hereditary patient is born, the patient cannot be cured radically, which brings trouble and heavy burden to the patient, family and society. Therefore, the prevention of the genetic diseases is important, and various examination measures are required to avoid the birth of children with the genetic diseases.
However, the current pregnancy test device determines whether the detected proportion of the head of the full-term fetal fetus occupying the whole body type is abnormal or not depending on the personal experience of the doctor, so that the determination result lacks objectivity and reliability.

Detailed Description
Embodiments of the term formed fetus topography analyzing system of the present invention will be described in detail with reference to the accompanying drawings.
The content of the pre-pregnancy examination of the human body by adopting the related medical instruments mainly comprises the following steps:
(1) general examination: such as height, weight, blood pressure and heart rate measurement, thyroid palpation, cardiopulmonary auscultation, liver and spleen palpation, four-limb spine examination, internal surgery, orthopedic examination, ear-nose-throat, oral cavity and ophthalmic examination.
(2) Laboratory examination: liver function (glutamic-pyruvic transaminase), serological five tests of hepatitis b, kidney function (creatinine), blood fat, blood sugar, blood routine (hemoglobin, erythrocytes, leukocytes and classification, platelets), thyroid function test (thyroid stimulating hormone), blood group (including ABO and RH blood groups), eugenic four items (rubella virus IgG antibody assay, toxoplasma IgM and IgG antibody assay, cytomegalovirus IgM antibody and IgG antibody assay, herpes simplex virus), G-6PD (6-phosphoglucose dehydrogenase), thalassemia screening, treponema pallidum screening, aids antibody, sex hormone level assay, urinary sediment analysis.
(3) And (3) electrocardiographic and imaging examination: electrocardiogram, high-frequency mammary gland color ultrasound, and B ultrasound (liver, gallbladder, spleen, pancreas, kidney, bladder, and uterus adnexa).

(5) Special inspection: if necessary, following the medical advice, the people with diabetes, hypertension and over-obesity also need to perform related special detection to ensure that the mother and fetus smoothly pass through the whole pregnancy and delivery period.
However, in the actual pregnancy test operation, for example, the judgment of whether the head of the full-term fetal fetus is abnormal or not depends on manual work, and automatic auxiliary judgment cannot be performed in a machine mode, so that the judgment efficiency is low and the judgment result is not accurate enough.
In order to overcome the defects, the invention builds a full-moon formed fetus shape analysis system, and can effectively solve the corresponding technical problem.

In addition, DDR3 video memory can be regarded as an improved version of DDR2, which has many similarities, and mainly adopts an FBGA packaging mode of 144Pin ball-type pins. However, the DDR3 core is improved: the DDR3 video memory adopts 0.11 micron production technology, and the power consumption is obviously reduced compared with the DDR 2. In addition, the DDR3 video memory adopts the "Pseudo Open Drain" interface technology, and as long as the voltage is appropriate, the display chip can directly support the DDR3 video memory. Of course, the longer latency (CAS latency) of video memory particles has been a common problem of high frequency video memory, and DDR3 is no exception, with DDR3 having CAS latency of 5/6/7/8 compared to DDR2 of 3/4/5. Surprisingly, DDR3 has no dramatic technical advance over DDR2, but the performance advantage of DDR3 is still significant: (1) the power consumption and the heat generation are small: the training of DDR2 is absorbed, energy consumption and heat productivity are reduced on the basis of controlling cost, and DDR3 is more easily accepted by users and manufacturers. (2) The working frequency is higher: due to the fact that energy consumption is reduced, DDR3 can achieve higher working frequency, the defect of long delay time is made up to a certain degree, and meanwhile, the DDR3 can serve as one of selling points of the video card, which is already shown on the video card matched with the DDR3 video memory. (3) The overall cost of the display card is reduced: the DDR2 video memory granule specification is mostly 4M X32 bit, and the 128MB video memory commonly used with middle and high-end video cards needs 8. The DDR3 video memory specification is mostly 8M X32 bit, the single particle capacity is large, and the 128MB video memory can be formed by 4 particles. Therefore, the area of the display card PCB can be reduced, the cost can be effectively controlled, and in addition, the display memory power consumption can be further reduced after the particle number is reduced. (4) The universality is good: DDR3 has better compatibility with DDR2 than DDR is changed to DDR 2. Because the key characteristics such as pins, packaging and the like are not changed, the DDR3 video memory can be adopted by slightly modifying the display core matched with the DDR2 and the video card designed by a public edition, and the cost is greatly reduced for manufacturers. At present, DDR3 is widely applied to most middle and high-end display cards which are newly existed.
