Design of a front-end integrated circuit for 3D acoustic imaging using 2D CMUT arrays
(IEEE-INST Electrical Electronics Engineers Inc, 2005-12)
Integration of front-end electronics with 2D capacitive micromachined ultrasonic transducer (CMUT) arrays has been a challenging issue due to the small element size and large channel count. We present design and verification ...
Coherent array imaging using phased subarrays. Part II: Simulations and experimental results
(IEEE-INST Electrical Electronics Engineers Inc, 2005-01)
The basic principles and theory of phased subarray (PSA) imaging imaging provides the flexibility of reducing I he number of front-end hardware channels between that of classical synthetic aperture (CSA) imaging-which uses ...
Film formation from pure and mixed latices; transient fluorescence study
(Academic Press Inc Elsevier Science, 2005-11-15)
A fast transient fluorescence technique was used to study latex film formation induced by organic solvent vapor. Mixtures of pyrene (P)- and naphthalene (N)-labeled and/or pure naphthalene-labeled latex films were prepared ...
Photon transmission study on conformational ordering of iota-carrageenan in CaCl2 solution
(Taylor & Francis Inc, 2005-06)
Coil-to-double helix (c-h) and double helix-to-dimer (h-d) phase transitions of iota-carrageenan in CaCl2 solution upon cooling were studied using photon transmission technique. Photon transmission intensity, I-iota r was ...
Coherent-array imaging using phased subarrays. Part I: Basic principles
(IEEE-INST Electrical Electronics Engineers Inc, 2005-01)
The front-end hardware complexity of a coherent array imaging system scales with the number of active array elements that are simultaneously used for transmission or reception of signals. Different imaging methods use ...
