Professor Jang Jin-ho developed ultrasonic array transducer appropriate for retinal disease diagnosis for the first time in the world
- Selected as a cover article on academic journal called IEEE Trans. on UFFC -
Sogang University Sogang Future Technology Center/Biointegrated Center/Department of Electronic Engineering Professor Jang Jin-ho research laboratory (Micro-Acoustic Functional Imaging Lab) announced an article. This was selected and published as the cover article in November 2015 edition of a renowned international journal called 'IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control'(Vol. 62, No. 14).
The title of published article is 'A 15-MHz 1-3 Piezocomposite Concave Array Transducer for Ophthalmic Imaging' and announced the research result about ultrasonic array transducer in concave shape that is appropriate for retinal disease diagnosis. And this was developed by professor Jang Jin-ho’s research team for the first time in the world.
Disease related to retinal includes detachment of the retina, diabetes retinopathy, retinal vein occlusion and so on. If the diagnosis and cure for disease related to retinal is not carried out on time, the patients have high chances of losing the sight. In order to accurately diagnose these retinal disease, it is necessary to have image device with high resolution of space in a wide range of image areas to do imaging of retinal’s transformation of shape due to disease and be able to accurately measure the speed change of retinal blood flow. However, so far there is no such image device that can provide all the necessary clinical information.
As announced in this article, ultrasonic array transducer in concave shape, as the ultrasonic sensor to transmit and receive ultrasonic signals, by assigning array elements in same shape as cornea and reduced the energy loss from cornea, at the same time, transmit and receive ultrasonic signals that have high frequencies. So when using this transducer in ultra-image device,can do imaging in wide area of retina parts also possible to have blood flow imaging, which can provide clinical information that is necessary for accurate diagnosis of retinal disease.
