Ultrasonic diagnostic apparatus, ultrasonic diagnostic method, and image processing program for ultrasonic diagnostic apparatus

Abstract

The present invention relates to an ultrasonic diagnostic apparatus, an ultrasonic diagnostic method, and an image processing program for the ultrasonic diagnostic apparatus. An image reconstruction unit converts B-mode image data and doppler mode image data into volume data with the common coordinate axes. A calculation unit calculates the estimated volume of a fetus based upon the volume data, and calculates the estimated weight of the fetus based upon a coefficient stored beforehand in a data storage unit and the estimated volume of the fetus thus calculated. A display unit displays the calculation results with respect to the estimated weight of the fetus etc. The ultrasonic diagnostic apparatus, the ultrasonic diagnostic method, and the image processing program for the ultrasonic diagnostic apparatus according to the present invention improves the operability of the ultrasonic diagnostic apparatus for calculating the estimated weight of a fetus.

Description

technical field [0001] The present invention relates to an ultrasonic diagnostic device, an ultrasonic diagnostic method, and an image processing program for the ultrasonic diagnostic device, and particularly to an ultrasonic diagnostic device and an ultrasonic diagnostic method capable of improving the operability of the ultrasonic diagnostic device. Background technique [0002] Conventionally, ultrasonic diagnostic apparatuses use sound waves, so there is no risk of being irradiated, so they have been used in the diagnosis of fetuses, etc., which are extremely vulnerable to radiation exposure. [0003] When an ultrasonic diagnostic apparatus is used for fetal diagnosis, a method of calculating an estimated fetal weight is conventionally known in order for a doctor or a technician (hereinafter referred to as "operator") to confirm the development status of the fetus. [0004] Using the previous method for calculating the presumed weight of the fetus, the current presumed w...

Problems solved by technology

[0010] However, in the conventional calculation method of estimated body weight or the method of applying the method proposed in JP-A No. 2-45046 to the conventional method of calculating estimated body weight of fetuses, the operator must sequentially display the fetal body weights required for the calculation of estimated body weight. After each tomographic image, measurement is performed based on each tomographic image. In addition, in order to calculate the estimated body weight with high accuracy, the operation panel provided on the input unit has to be displayed several times to display the optimal tomographic image. Said that the operation is more cumbersome

[0011] Therefore, although a method of calculating the estimated fetal weight using a tomographic image displayed by one display operation is also considered, for example, in the case of measuring BPD (biparietal diameter of the fetal head) by displaying a tomographic image of the fetal head, the When the tomographic image displayed by one display operation is not the tomographic image perpendicular to the fetal head (so-called axial tomographic image), but the tomographic image is scanned slightly inclined to the tomographic image on the axial plane, because the The ellipse becomes flatter, so a two-dimensional error occurs in the measurement, and as a result, the estimated weight of the fetus cannot be calculated with high accuracy

[0012] In addition, before calculating the estimated weight of the fetus, it is necessary to perform multiple operations on multiple items, but sometimes the operator forgets to operate one of the items. In this case, although it takes time to perform operations on other items, the Because I forgot to operate one item, the estimated fetal weight could not be calculated, and the estimated fetal weight had to be calculated again

Therefore, there is a problem that the operation is troublesome for the operator.
