High density trans-admittance mammography development and preliminary phantom tests
BACKGROUND Malignant breast tumor tissue has a significantly different electrical impedance spectrum than surrounding normal tissues. This has led to the development of impedance imaging as a supplementary or alternative method to X-ray mammography for screening and assessment of breast cancers. However low spatial resolution and poor signal to noise ratio has limited the clinical application. ...
متن کاملA compensated radiolucent electrode array for combined EIT and mammography.
Electrical impedance tomography (EIT), a non-invasive technique used to image the electrical conductivity and permittivity within a body from measurements taken on the body's surface, could be used as an indicator for breast cancer. Because of the low spatial resolution of EIT, combining it with other modalities may enhance its utility. X-ray mammography, the standard screening technique for br...
متن کاملA New Trans-admittance Mode Biquad Filter using MO-VDTA
In this paper, a new trans-admittance-mode biquad filter configuration based on two multi output voltage differencing transconductance amplifiers (MO-VDTAs) as newly active elements is proposed which also consists of two grounded MOS resistors and two capacitors with one of the capacitor is being permanently grounded. The proposed configuration is competent of realizing trans-admittance-mode lo...
متن کاملA feasibility study of a rotary planar electrode array for electrical impedance mammography using a digital breast phantom.
A feasibility study of an electrical impedance mammography (EIM) system with a rotary planar electrode array, named RPEIM, is presented. The RPEIM system is an evolution of the Sussex MK4 system, which is a prototype instrument for breast cancer detection. Comparing it with the other planar electrode EIM systems, the rotation feature enables a dramatic increase in the number of independent meas...
متن کاملA New Trans-admittance-Mode Biquad Filter Suitable for Low Voltage Operation
The trans-admittance-mode (TAM) might act as a transforming bridge for voltage-mode to current-mode conversion. In this study a new low voltage operated electronically tunable TAM biquad filter structure realizing all the seven standard filtering functions namely; low-pass (LP), band-pass (BP), high-pass (HP), regular-notch (RN), low-pass-notch (LPN), high-pass-notch (HPN) and all-pass (AP) fro...
