Medical ultrasonic sensors to keep a close eye on the human body
Where are ultrasonic sensors used? (Medicine)

Since ultrasonic sensors can visualize the internal condition of the human body without damaging them, they are widely used in various medical inspections including prenatal examinations to which radiography cannot be applied.
Because of it's ability of real-time visualization, the sensors can also be used for tissue biopsy sampling or therapeutics while locating the target organ.

Ultrasonic sensors are now indispensable to the medical field.


Abdomen diagnosis
Mammary and thyroid glands diagnosis
Circulatory diagnosis
Transvaginal and transrectal diagnosis
Vascular diagnosis
Eye axis length measurement

*Besides the examples of diagnosis shown above, ultrasonic sensors are also used for many other different diagnostic and therapeutic applications


Abdomen diagnosis

Abdomen diagnosis

Ultrasonic sensors are used for diagnosis of internal organs including liver, kidneys, pancreas and gallbladder or watching fetal growth and health condition of the pregnant women.

How cool!Mechanical scan for 3D imaging


Mechanically moving the electronic scanning convex type probe over the abdomen of a pregnant woman in a fan shape will acquire 3D data to produce images. The moving speed and angle can be adjusted to acquire 3D image data suitable for your purpose of use.
From the 3D data, it is possible to obtain cross-section images at any given point of the axis (horizontal plane) perpendicular to the direction of propagation of ultrasonic waves from the probe that cannot be viewed in traditional 2D images. This provides even wider information for diagnosis.




Mammary and thyroid glands diagnosis

Mammary and thyroid glands diagnosis

Ultrasonic sensors are used for breast cancer check-ups to detect the presence of lumps under breasts or any changes in their shape, and for thyroid gland examinations to detect the presence of lumps inside the neck.

How Cool!Linear scan


This linear type uses the world's first "linear scan" technology that allows the built-in probe to directly move in a lateral direction (reciprocal scan) by a motor.
Compared to the traditional arc scanning, this linear scanning provides higher lateral resolution of diagnostic images.
The probe also has a flat surface that touches the target part of the human body (the surface that sends and receives ultrasonic waves). This geometry allows the probe to ensure more uniform contact with the irregular surface of breasts and other parts of the human body.




Cardiology diagnosis

Ultrasonic scanners are used for cardiac diagnosis to capture the size of the heart and to check it for shape or movement abnormality as well as to determine the heart blood flow condition.
