To verify the concept of our proposed scheme, we performed pulse-echo detection, and accessed therapeutic effects of human cervical cancer cells exposed to acoustic stimulation experiments using 100 MHz focused piezoelectric transducer triggered by PA with and without the proposed shunt-diode pre-linearizer scheme. In the pulse-echo detection responses, the peak-to-peak voltage of the echo signal when using the PA with shunt-diode pre-linearizer (49.79 mV) was higher than that when using the PA alone (29.87 mV). In the experimental results, the cell densities of cancer cells on Day 4 when using no acoustic stimulation (control group), the very high-frequency piezoelectric transducer triggered by PA only and PA combined with proposed pre-linearizer schemes (1 V and 5 V DC bias voltages) showed 100%, 92.8 \u00b1 4.2%, 84.2 \u00b1 4.6%, and 78 \u00b1 2.9%, respectively. Therefore, we confirmed that the shunt-diode pre-linearizer could improve the performances of the pulse signals of the PA, thus, enabling better therapeutic stimulation performances for cancer cell suppression.<\/jats:p>","DOI":"10.3390\/s19020357","type":"journal-article","created":{"date-parts":[[2019,1,17]],"date-time":"2019-01-17T03:02:03Z","timestamp":1547694123000},"page":"357","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Acoustic Stimulation by Shunt-Diode Pre-Linearizer Using Very High Frequency Piezoelectric Transducer for Cancer Therapeutics"],"prefix":"10.3390","volume":"19","author":[{"given":"Hojong","family":"Choi","sequence":"first","affiliation":[{"name":"Department of Medical IT Convergence Engineering, Kumoh National Institute of Technology, Gumi 39253, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7298-4147","authenticated-orcid":false,"given":"Se-woon","family":"Choe","sequence":"additional","affiliation":[{"name":"Department of Medical IT Convergence Engineering, Kumoh National Institute of Technology, Gumi 39253, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2019,1,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1935","DOI":"10.1109\/TBME.2016.2631224","article-title":"A Modulated Excitation Imaging System for Intravascular Ultrasound","volume":"64","author":"Qiu","year":"2016","journal-title":"IEEE Trans.
