Haemmerich D, Staelin S, TSAI J, Tungjitkusolmun S, Mahvi D, Webster J
Physiol Meas
. 2003 Jun;
24(2):251-60.
PMID: 12812412
Knowledge of electrical tissue conductivity is necessary to determine deposition of electromagnetic energy and can further be used to diagnostically differentiate between normal and neoplastic tissue. We measured 17 rats...

Haemmerich D, Ozkan R, Tungjitkusolmun S, TSAI J, Mahvi D, Staelin S, et al.
Med Biol Eng Comput
. 2002 Apr;
40(1):29-33.
PMID: 11954705
The resistivity of swine liver tissue was measured in vivo, during induced ischaemia and post-mortem, so that associated changes in resistivity could be quantified. Plunge electrodes, the four-terminal method and...

Haemmerich D, Staelin S, Tungjitkusolmun S, Lee Jr F, Mahvi D, Webster J
IEEE Trans Biomed Eng
. 2001 Oct;
48(10):1145-52.
PMID: 11585038
Radio-frequency (RF) ablation has become an important means of treatment of nonresectable primary and metastatic liver tumors. Major limitations are small lesion size, which make multiple applications necessary, and incomplete...

Cao H, Vorperian V, Tungjitkusolmun S, TSAI J, Haemmerich D, Choy Y, et al.
IEEE Trans Biomed Eng
. 2001 Apr;
48(4):425-33.
PMID: 11322530
This study investigated the flow effect on the lesion formation during radio-frequency cardiac catheter ablation in temperature-controlled mode. The blood flow in heart chambers carries heat away from the endocardium...

Tungjitkusolmun S, Vorperian V, Bhavaraju N, Cao H, TSAI J, Webster J
IEEE Trans Biomed Eng
. 2001 Apr;
48(2):194-201.
PMID: 11296875
We used the finite element method to study the effect of radio-frequency (RF) catheter ablation on tissue heating and lesion formation at different intracardiac sites exposed to different regional blood...

Tungjitkusolmun S, Woo E, Cao H, TSAI J, Vorperian V, Webster J
Med Biol Eng Comput
. 2000 Nov;
38(5):562-8.
PMID: 11094815
Finite element (FE) analysis has been utilised as a numerical tool to determine the temperature distribution in studies of radio frequency (RF) cardiac ablation. However, none of the previous FE...

Cao H, Vorperian V, TSAI J, Tungjitkusolmun S, Woo E, Webster J
IEEE Trans Biomed Eng
. 2000 Nov;
47(11):1518-24.
PMID: 11077746
While most commercial ablation units and research systems can provide catheter tip temperature during ablation, they do not provide information about the temperature change inside the myocardium, which determines the...

TSAI J, Cao H, Tungjitkusolmun S, Woo E, Vorperian V, Webster J
IEEE Trans Biomed Eng
. 2000 Jan;
47(1):41-8.
PMID: 10646278
The apparent resistance of a finite-thickness layer measured with a four-electrode plunge probe depends on the electrode insertion depth, electrode spacing, and layer thickness, as well as the resistivity ratio...

Tungjitkusolmun S, Woo E, Cao H, TSAI J, Vorperian V, Webster J
IEEE Trans Biomed Eng
. 2000 Jan;
47(1):32-40.
PMID: 10646277
The high current density at the edge of a metal electrode causes hot spots, which can lead to charring or blood coagulation formation during radio-frequency (RF) cardiac ablation. We used...
