Photoacoustic (PA) or optoacoustic imaging is a relatively new imaging modality based on the detection of light-excited ultrasound waves, has emerged as one of the most exciting research areas in biomedical imaging over the past decade [1-4]. In PA imaging, nanosecond pulsed (or modulated) electromagnetic radiation is delivered into tissues to excite ultrasound waves via photon absorption and t...

Ultrasound is a widely used imaging modality for evaluation of the prostate. The main topic of diagnostic imaging is an improvement of prostate cancer diagnosis. The current available systematic prostate biopsy is performed only under ultrasound guidance, but new imaging techniques allow prostate cancer visualization and therefore improved detection. Evolving methods such as contrast-enhanced c...

Ultrasound is an increasingly popular imaging modality in image-guided interventions, due to its safety, accessibility, and low cost. But ultrasound imaging has a steep learning curve, and requires significant coordination skills from the operator. It is difficult to interpret cross-sectional anatomy in arbitrary angles, and even more challenging to orient a needle with respect to the ultrasoun...

the imaging of hepatocellular carcinoma (hcc) is challenging and plays a crucial role in the diagnosis and staging of the disease. a variety of imaging modalities, such as ultrasound, computed tomography (ct), magnetic resonance imaging (mri) and nuclear medicine are currently used in evaluating patients with hcc. although the best option for the treatment of these cases is hepatic resection or...

BACKGROUND Image contrast between normal tissue and brain tumours may sometimes appear to be low in intraoperative ultrasound. Ultrasound imaging of strain is an image modality that has been recently explored for intraoperative imaging of the brain. This study aims to investigate differences in image contrast between ultrasound brightness mode (B-mode) images and ultrasound strain magnitude ima...

up to 19% of breast malignancies may be missed by conventional imaging techniques, especially when they are concurrent or co-located with other benign lesions. however, more sensitive techniques, such as magnetic resonance imaging (mri), are often too expensive for routine use in developing countries. contrast-enhanced, dual-energy digital mammography (cesm) is a recently introduced imaging mod...

Image processing plays a vital role in the development of medical industry especially ultrasound medical images. Image acquisition is carried out using ultrasound equipments like transducer, scanner, and CPU and display device. There are mainly four modes of ultrasound imaging A-mode, M-mode, B-mode and Doppler-mode. Ultrasound imaging plays crucial role in medical imaging due to its non-invasi...

By transmitting acoustic energy into the body and receiving and processing the returning reflections, phased-array ultrasound systems can generate images of internal organs and structures, map blood flow and tissue motion, and provide highly accurate blood velocity information. Historically, the large number of high-performance phased-array transmitters and receivers required to implement these...
