Embodiment Construction

[0036] Next, preferred embodiments of the present invention will be described based on the drawings.

[0037] The ultrasonic diagnostic apparatus 10 is generally installed in a medical institution such as a hospital, and is a medical device for performing ultrasonic diagnosis on a subject. The ultrasonic diagnostic apparatus 10 forms ultrasonic images for various inspections or measurements. The ultrasonic diagnostic apparatus 10 has a function of measuring the distance between two designated measurement points on a formed ultrasonic image. Next, the distance measurement function of the ultrasonic diagnostic apparatus 10 will be described by taking the measurement of the biparietal diameter for confirming the developmental state of the fetus as an example. In addition, the ultrasonic diagnostic apparatus 10 is a type of ultrasonic image processing apparatus in the specification of this application.

Abstract

According to the present invention, when measurement of a distance (fetal head biparietal diameter) on an ultrasonic image is started, a first mobile marker for designating a start point and a standard range display graphic are displayed. The standard range display graphic is a graphic that is centred on the first mobile marker and comprises two circular graphics having radii that are configured to be a lower limit and upper limit of a fetal head biparietal diameter standard range. A user can designate the start point while recognizing, via the standard range display graphic, an end point candidate range. Subsequently, an end point can be designated while recognizing the end point candidate range via a stationary standard range display graphic.

Description

technical field [0001] The invention relates to an ultrasonic image processing device, in particular to an ultrasonic image processing device for performing distance measurement on an ultrasonic image. Background technique [0002] Ultrasonic images are formed by an ultrasonic diagnostic apparatus that transmits and receives ultrasonic waves to and from a subject. Ultrasonic images can be used for various inspections or measurements. For example, the diameter of the fetal head (fetal head biparietal diameter) is measured in order to investigate the developmental state of the fetus. In this measurement, the distance from the cranium of the right head to the cranium of the left head is measured on an ultrasonic image (B-mode image) including a section of the fetal head. [0003] More specifically, usually on the B-mode image displayed on the display unit, a user such as a physician sequentially designates two measurement points, and the distance between the two measurement p...
