Multiple-source quantitative photoacoustic tomography

Photoacoustic tomography (PAT) is a novel hybrid medical imaging technique that aims to combine the large contrast of optical coefficients with the high resolution capabilities of ultrasounds. We assume that the first step of PAT, namely the reconstruction of a map of absorbed radiation from boundary ultrasound measurement, is done. We focus on quantitative photoacoustic tomography (QPAT), whic...

Internet Tomography

Realizing a Source Authentic Internet

An innate deficiency of the Internet is its susceptibility to IP spoofing. Whereas a router uses a forwarding table to determine where it should send a packet, previous research has found that a router can similarly employ an incoming table to verify where a packet should come from, thereby detecting IP spoofing. Based on a previous protocol for building incoming tables, SAVE, this paper introd...

Multiple-bandwidth photoacoustic tomography.

Photoacoustic tomography, also referred to as optoacoustic tomography, employs short laser pulses to generate ultrasonic waves in biological tissues. The reconstructed images can be characterized by the convolution of the structure of samples, the laser pulse and the impulse response of the ultrasonic transducer used for detection. Although the laser-induced ultrasonic waves cover a wide spectr...

Assessment of transposition of the great arteries associated with multiple malformations using dual-source computed tomography

PURPOSE To determine the value of dual-source computed tomography (DSCT) in depicting the morphological characteristics and diagnosing the associated malformations for patients with transposition of the great arteries (TGA) before surgery. MATERIALS AND METHODS Twenty-five patients with TGA who underwent DSCT and transthoracic echocardiography (TTE) examination were retrospectively reviewed. ...
