Description
Technical field
The present invention relates to ultrasonic diagnosis and medical instruments field, more particularly relate to a kind of through ultrasonic quantitative measurement and the system that analyzes development condition of baby skull.
Background technology
Mother's phenolics is calcareous can to cause the dysplasia of neonatal skull sutura with deficiency irony, and the malnutrition of age of sucking can have a strong impact on neonatal skull normal growth and intelligence development.The baby is very fast to the one year old speed of growth from being born, and balanced growth within postnatal a year can reach 12 centimetres like head circumference.The cradle bone growth and development needs enough vitamin D and calcium, replenishes as untimely, and " cephalus quadratus " deformity, i.e. craniotabes disease appear in the fontanel that is positioned at the crown closure that after birth, can delay.The ossific process of the closure reflection skull of bregma and sutura, the closed microcephaly that forms easily too early, closure is more common in rickets, hydrocephalus or cretinism etc. too late.Therefore monitoring baby's skull development condition has crucial meaning to its healthy growth in real time.But at present clinical skull development condition to the baby just comes subjective judgment through observation and touch, does not have quantitative methods to carry out objective measurement and analysis.
Summary of the invention
Can't quantitative measurement and the problem of analysis in order to overcome present development condition of baby skull; Development condition of baby skull quantitative measurement of the present invention and analytical system are applied to ultrasonic technique and electromagnetic location technology the baby skull measurement and analyze; Because the radiationless damage of ultrasound wave, so the present invention can be used safely in baby's skull measurement.
