A popular method introduced in ultrasound tomography is the Distorted Born Iterative Method (DBIM). Recently, the dual-frequency combination technique has been utilized to improve the reconstruction quality and increase the convergence rate of the DBIM. This method uses two frequencies, f1<\/jats:sub> (low) and f2<\/jats:sub> (high), to estimate the sound contrast in [Formula: see text] and [Formula: see text] iterations, respectively. However, the influence of these iteration parameters on the overall performance of the system is not yet known. In this paper, it is shown by using the simulation technique that if we do not pay attention to the choice of these parameters, the reconstruction quality might be worse than that using a single frequency. Furthermore, we focus on the best way to select the parameters in order to improve the reconstruction quality of ultrasound tomography. Given a fixed sum [Formula: see text] of [Formula: see text] and [Formula: see text], simulation results show that the best value of [Formula: see text] is [Formula: see text]\/2; this choice of parameters offers a normalized error that reduces by 67.6%, compared to the conventional DBIM using a single frequency. <\/jats:p>","DOI":"10.1177\/0037549716630605","type":"journal-article","created":{"date-parts":[[2016,2,20]],"date-time":"2016-02-20T03:44:12Z","timestamp":1455939852000},"page":"267-276","update-policy":"http:\/\/dx.doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Influence of dual-frequency combination on the quality improvement of ultrasound tomography"],"prefix":"10.1177","volume":"92","author":[{"given":"Quang-Huy","family":"Tran","sequence":"first","affiliation":[{"name":"Ha Noi Pedagogical University No2, Vietnam"},{"name":"VNU University of Engineering & Technology, Vietnam"}]},{"given":"Duc-Tan","family":"Tran","sequence":"additional","affiliation":[{"name":"VNU University of Engineering & Technology, Vietnam"}]},{"given":"Huu Tue","family":"Huynh","sequence":"additional","affiliation":[{"name":"VNU International University, Vietnam"}]},{"given":"Long","family":"Ton-That","sequence":"additional","affiliation":[{"name":"VNU International University, Vietnam"}]},{"given":"Linh-Trung","family":"Nguyen","sequence":"additional","affiliation":[{"name":"VNU University of Engineering & Technology, Vietnam"}]}],"member":"179","published-online":{"date-parts":[[2016,2,19]]},"reference":[{"key":"bibr1-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1109\/ULTSYM.1995.495819"},{"key":"bibr2-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-49197-2_46"},{"key":"bibr3-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1002\/jcu.1870100207"},{"key":"bibr4-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1007\/1-4020-5721-0_20"},{"key":"bibr5-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1088\/0266-5611\/21\/2\/015"},{"key":"bibr6-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1118\/1.1897463"},{"key":"bibr7-0037549716630605","first-page":"708","volume-title":"International conference on biomedical engineering and informatics","volume":"2","author":"Li C","year":"2008"},{"key":"bibr8-0037549716630605","first-page":"399408","volume":"24","author":"Jeong JW","year":"2005","journal-title":"IEEE Trans Med Imag"},{"key":"bibr9-0037549716630605","first-page":"147154","volume":"28","author":"Johnson SA","year":"2007","journal-title":"Acoust Imaging"},{"key":"bibr10-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1364\/OL.7.000111"},{"key":"bibr11-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1109\/TMTT.1984.1132783"},{"key":"bibr12-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4419-8588-0_96"},{"key":"bibr13-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1109\/58.738288"},{"key":"bibr14-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1088\/0266-5611\/17\/6\/307"},{"key":"bibr15-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1109\/TUFFC.2010.1713"},{"key":"bibr16-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1017\/CBO9781139644181"},{"key":"bibr17-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1109\/TMI.2009.2026274"},{"key":"bibr18-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1137\/S0895479897326432"},{"key":"bibr19-0037549716630605","doi-asserted-by":"publisher","DOI":"10.1109\/TUFFC.2008.621"},{"volume-title":"New developments on quantitative imaging using ultrasonic waves","year":"2009","author":"Lavarello R.","key":"bibr20-0037549716630605"},{"key":"bibr21-0037549716630605","unstructured":"Avinash CK, Slaney M.
