SYNTHETIC APERTURE
Description
A system with 64channels obtains the same image quality as in the system with 128channels as follows.
In a normal state, a system receives and transmits with the below 64 elements of B and C. First, receive and transmit with 64 elements of B and C, and store RF data into line memory.
Secondly, if you transmit with 64 elements of B and C, receive with 64 elements of A and D, and then add the stored data through synchronization, you will have the same premium image quality as that in a system with 128 channels.
In the above procedure, you have higher image quality than under the normal operation whereas frame rate decreases half as many as the original rate.
TRADEZOIDAL IMAGE
Description
Conventional rectangular images of linear-array probe have a weakness that it cannot display wide area.
To compensate the limitation, wide area can be produced with trapezoidal imaging and extends the field of view while maintaining resolution. It can be realized by grouping elements in the similar way as scanning method of linear probe and steering at an adequate angle per scanline.
With 20% more clinical information than a typical image, trapezoidal imaging is most useful in vascular and thyroid imaging, allowing complete measurements to be obtained in a single image.
(Comfortable and accurate Diagnosis by artifact-free color doppler)
Description
CAFE™ Plus is the abbreviation of ‘Compound Automatic Flash Elimination Plus’, which is mostly important in color flow imaging to acquire non-flash artifact image. When acquiring data of vessels by Doppler signal, useless flash artifacts arose, which we call clutter signal.
This clutter signal usually shows 100 times difference signal in actual Doppler signal. And thus, filtering algorithm is applied to get rid of the clutter signal.
High pass filter provides mode-specific non-linear filtering and eliminates the pixels that form flash artifacts for much clearer image. We call this automatic filtering algorithm, a CAFE™ Plus.
(CAFE™ Plus is the upgraded version of CAFE™).
Clinical benefits
Enables automatic volume scan with a single key motion as an electronic sector transducer
Scan volume of human body to enable 3D analysis of single section of internal volume Provide high-quality and sharp image with high resolution, high frame rate, wide dynamic range, excellent penetration, wide view angle using true 3D multi-beam Provide volume image enabling select single plane of internal volume to observe simultaneously and in realtime the mutual intuition of the 3 individual planes(coronal, sagittal, transverse) Application areas include 3D, 4D and realtime images of obstetrics, gynecology, and urology enabling new dimensional diagnosis of 3D and 4D of malformation, organ volume and status of blood flow. Volume mode provides coronal plane, not offered with 2D technology, to enable color and power 3D with excellent Doppler sensitivity and power Doppler sensitivity.
PULSE INVERSION HARMONIC IMAGING
Description
Pulse Inversion Harmonic image provides exceptional pure harmonic image in cardiac imaging.
It works by sending an ultrasound pulse into the body, then digitally storing the received fundamental signal as well harmonic signal.
Then, a pulse that is the inversion of the original fundamental signal is sent into the body and repeats digitally storing both inverse fundamental and harmonic signal Finally, these two pulses are summed so that the fundamental signals combines to provide exceptionally high spatial resolution.
The result of Pulse Inversion Harmonic Imaging is visualization of minute amounts of contrast agent with very high spatial resolution allowing confident assessment of cardiac imaging.
FINE™ FILTER
(Filtered image for noise reduction & edge enhancemet)
Description
FINE™ FILTER (Filtered Image for Noise reduction & Edge enhancement) technology provides excellent clear 2D images by accepting 2D filtering methods: edge enhancement and noise reduction filtering.
Figure 1 describes input signal and figure 2 describes filtered out put signal. As seen in the figure 2, FINE™ filtering reduces noise through low-pass filtering and smoothes the signal. In the mean time, high pass providers fine image with edge enhancement. FINE™ filter is applied in 2D real-time for edge enhanced signal and smooth filtering to provide better contrast resolution with small speckle pattern.
