ULTRASOUND SYSTEM FOR CONTROLLING TO DISPLAY ACCORDING TO MEASURED VALUE OF OBJECT AND METHOD THEREOF}

Embodiments of the present invention relate to a method for identifying an abnormality of a fetus by using a fetus's trunk length and a fetus's neck thickness measured from a volume image obtained by scanning a fetus.

The ultrasound system transmits an ultrasound signal from a body surface to a predetermined part of the body (ie, an object such as a fetus or an organ), and uses the information of the ultrasound signal reflected from tissues of the body to determine the soft tissue tomography or blood flow. It is a device for obtaining images.

These ultrasound systems are compact, inexpensive, displayable in real time, and have high stability because they do not have exposure to X-rays, and thus have X-ray diagnostics, computerized tomography (CT) scanners, magnetic resonance image (MRI) devices It is widely used with other image diagnosis apparatuses, such as a nuclear medical diagnostic apparatus.

On the other hand, a common method of discriminating Down syndrome fetus is to measure the thickness of the fetal neck translucency (NT) by ultrasound system. In particular, babies with chromosomal abnormalities or heart malformations, including Down syndrome, are often thickened in the neck. Therefore, the doctor measures the thickness of the transparent part at the back of the fetus's neck using an ultrasound system, and if the thickness is greater than 2.5 mm, the doctor examines the fetal abnormality by more precise methods such as chorionic biopsy or amniotic fluid. You see.

However, since the thickness of the neck brace, which is normally measured according to the age of the fetus, varies, the thickness of the neck brace for judging Down syndrome is compared with the length of the fetus's body suitable for the age of the fetus. There is a need for an accurate judgment.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to or limited by the embodiments. Like reference symbols in the drawings denote like elements.

FIG. 1 is a diagram illustrating an internal configuration of an ultrasonic inspector for controlling display according to a measured value of an object in an embodiment of the present invention.

Referring to FIG. 1, an ultrasound inspector 100 (hereinafter, referred to as an “ultrasound inspector”) that controls display according to a measurement value of an object includes a first measuring unit 110, a second measuring unit 120, and a determining unit 130. ), The display controller 140, and the mapping table 150.

The ultrasound inspector 100 acquires a volume image of the object 170 through a scan using the probe 160. The ultrasound inspector 100 may scan the object 170 that the probe 160 contacts, and acquire a volume image. For example, an object is a concept including a fetus and an organ, and the ultrasound scanner 100 may generate a 3D volume image by scanning a fetus located in a mother's abdomen.

As an example of generating a volume image, the ultrasound inspector 100 may set Regions of Interest for an object through a scan unit (not shown), and place seeds within the set ROI. Can be. In this case, when the object is a fetus, the seed may be located near a fetal neck translucency (NT). Thereafter, the scan unit scans the fetus using 3D ultrasound to create image data, thereby generating a volume image of the object.

The first measurement unit 110 generates length data associated with the object from the volume image of the object obtained through the scan. In an embodiment, when the object is a fetus, the first measuring unit 110 identifies the head and the torso of the fetus in the volume image and identifies the 'length from the head to the torso' (CRL: Crown Rump). Length) can be generated as the length data.

The second measurement unit 120 generates measurement data at a selected measurement point in the volume image. In an embodiment, when the object is a fetus, the second measuring unit 120 is selected as a measuring point around the neck of the fetus (NT, Nuchal Translucency), and identifies and identifies the selected fetal neck translucent band. The 'thickness of the neck transparent band' can be generated as the measurement data.

2 is a diagram illustrating an example of generating length data and measurement data from volume images acquired from an object.

Referring to FIG. 2, the first measurement unit 110 may generate the length CRL from the head of the fetus to the hip as the length data 210. The length data may change in length as the fetus ages.

The second measurement unit 120 may be selected as a measurement point around the neck of the fetus neck (NT), and generate the selected thickness of the neck of the fetus as the measurement data 220. The measured data also changes in the thickness of the neckband as the fetus ages.

Therefore, the length data and the measured data measured according to the age of the fetus can be changed in proportion or inversely.

Measuring the neckline of the fetus is a common way to differentiate Down's syndrome fetus. In fetuses with chromosomal abnormalities or heart abnormalities, including Down syndrome, the neck is often thickened. Therefore, the doctor measures the thickness of the transparent portion on the back of the fetus's neck through the ultrasound scanner 100, if the thickness of the portion is more than 25mm, abnormalities of the fetus in a more precise method such as chorionic biopsy or amniocentesis Let's take a look.

However, since the thickness of the neck brace to determine Down syndrome is changed according to the age of the fetus, it is necessary to accurately determine the abnormality of the fetus according to the correlation between the trunk length measured by the age of the fetus and the thickness of the neck brace. .

To this end, the determination unit 130 determines a correlation between the length data and the measurement data, and determines the risk level for the measurement data.

The mapping table 150 records the permissible ranges for the measurement points for each length data. The allowable range for the measurement point may include a length that can be determined that the thickness of the neck transparent belt measured according to the age of the fetus is normal. For example, the mapping table 150 records the length of the neck strap greater than '18 mm 'or less than '22 mm' in an allowable range in correspondence with the length data (40 mm) of the 12 weeks fetus, and the length data of the 16 weeks fetus. Corresponding to (50mm), the thickness of the neck strap can be recorded as the allowable range of greater than 20mm or less than 25mm.

The determination unit 130 may determine whether the measurement data is included within the allowable range recorded in the mapping table 150 corresponding to the generated length data as the correlation. For example, when the measured length data is '39 mm ', the determining unit 130 determines whether the measured data is included in an allowable range larger than '18 mm' or smaller than '22 mm 'between the length data and the measured data. It can be judged as correlation.

The determination unit 130 (1) if it is determined that the measurement data is included within the allowable range, determine the risk to 'low', and (2) if it is determined that the measurement data is not included within the allowable range The risk may be determined as 'high'. For example, the determination unit 130 determines that the risk is low when the measured length data is included in an allowable range larger than 18 mm or smaller than 22 mm when the measured length data is '39 mm '. If not included (less than '18 mm 'or greater than '22 mm'), the risk may be determined as 'high'.

The display controller 140 displays the determined risk on the screen area displaying the volume image. Alternatively, the display control unit 140 displays the determined risk level in a pop-up form, or divides the screen into a plurality of screen areas including a first screen area and a second screen area, and the length of the first screen area. The measured value related to the data may be displayed, or the determined risk may be displayed on the second screen area.

Therefore, the ultrasound scanner 100 accurately grasps the thickness of the neck transparent belt that varies depending on the age of the fetus so that the accurate examination of the fetus can be made.

3 is a diagram illustrating an example of displaying a risk level on measurement data on a screen area.

Referring to FIG. 3, the display controller 140 may display a risk (low risk: low) determined by the determiner 130 on a screen area displaying the volume image (310).

Alternatively, the display controller 140 may display the determined risk in a popup form (risk 'high') (310).

Alternatively, the display control unit 140 divides the screen into a plurality of screen areas including a first screen area and a second screen area, and measures measured values (CRL: 40 mm and 20 mm related to the length data in the first screen area). , 20.5mm, HC: 20mm, BPD: 20.5mm) or the determined risk (NT: 3mm, risk: high) on the second screen area (330). For reference, HC stands for Head Circumference, which means head circumference, and BPD stands for Biparietal diameter, which means skull diameter.

4 is a flowchart illustrating a procedure of a display control method according to a measured value of an object in an ultrasound inspector according to an exemplary embodiment of the present invention.

Referring to FIG. 4, in operation 410, the ultrasound inspector 100 generates length data associated with the object from the volume image of the object obtained through the scan. In an embodiment, when the object is a fetus, the ultrasound scanner 100 identifies the head and the torso of the fetus in the volume image, and identifies the length CRL from the identified head to the torso as the length data. Can be generated.

In operation 420, the ultrasound inspector 100 generates measurement data at a selected measurement point in the volume image. In an embodiment, when the object is a fetus, the ultrasound scanner 100 is selected as a measuring point around the neck of the fetus neck (NT), to identify the selected neck of the fetus, and the identified neck The thickness can be generated as the measurement data.

In operation 430, the ultrasound scanner 100 determines a correlation between the length data and the measurement data to determine a risk level for the measurement data. The ultrasound inspector 100 may determine whether the measurement data is included within the allowable range recorded in the mapping table 150 corresponding to the generated length data as the correlation. For example, if it is determined that the measurement data is within the allowable range, the ultrasound inspector 100 determines the risk to be 'low', and if it is determined that the measurement data is not included within the allowable range, the ultrasound degree is determined. It can be determined as 'high'.

Thereafter, the ultrasound scanner 100 displays the determined risk on the screen area displaying the volume image 310, displays the determined risk in a pop-up form 320, or displays the screen on the first screen area. And a plurality of screen areas including a second screen area, a measurement value related to the length data may be displayed on the first screen area, or the determined risk may be displayed on the second screen area (330). ).

Therefore, the ultrasound scanner 100 displays the risk on the screen area of the neck according to the correlation between the body length of the fetus and the thickness of the neck of the fetus on the screen area, allowing the doctor to intuitively check the risk of the fetus through the screen.
