Propagation of measurement noise through backprojection reconstruction in electrical impedance tomography
IEEE Transactions on Medical Imaging - Tập 21 Số 6 - Trang 566-578 - 2002
A framework to analyze the propagation of measurement noise through backprojection reconstruction algorithms in electrical impedance tomography (EIT) is presented. Two measurement noise sources were considered: noise in the current drivers and in the voltage detectors. The influence of the acquisition system architecture (serial/semi-parallel) is also discussed. Three variants of backprojection re...... hiện toàn bộ

Statistical analysis of nonlinearly reconstructed near-infrared tomographic images. II. Experimental interpretation
IEEE Transactions on Medical Imaging - Tập 21 Số 7 - Trang 764-772 - 2002
For pt. I see ibid., vol. 21, no. 7, p. 755-63 (2002). Image error analysis of a diffuse near-infrared tomography (NIR) system has been carried out on simulated data using a statistical approach described in pt. I of this paper (Pogue et al., 2002). The methodology is used here with experimental data acquired on phantoms with a prototype imaging system intended for characterizing breast tissue. Re...... hiện toàn bộ

Imaging of thoracic blood volume changes during the heart cycle with electrical impedance using a linear spot-electrode array
IEEE Transactions on Medical Imaging - Tập 21 Số 6 - Trang 653-661 - 2002
Electrical impedance (EI) measurements conducted on the thorax contain useful information about the changes in blood volume that occur in the thorax during the heart cycle. The aim of this paper is to present a new (tomographic-like) method to obtain this relevant information with electrical impedance measurements, using a linear electrode array. This method is tested on three subjects and the res...... hiện toàn bộ

Exact frequency-domain reconstruction for thermoacoustic tomography. II. Cylindrical geometry
IEEE Transactions on Medical Imaging - Tập 21 Số 7 - Trang 829-833 - 2002
For pt. I see ibid., vol. 21, no. 7, p. 823-8 (2002). Microwave-induced thermoacoustic tomography (TAT) in a cylindrical configuration is developed to image biological tissue. Thermoacoustic signals are acquired by scanning a flat ultrasonic transducer. Using a new expansion of a spherical wave in cylindrical coordinates, we apply the Fourier and Hankel transforms to TAT and obtain an exact freque...... hiện toàn bộ
