Improved image quality with new ultrasound imaging techniques

A New Method in Image Steganography with Improved Image Quality

"Steganography” is a Greek origin word which means “hidden writing”. Steganography word is classified into two parts: Steganos which means “secret or covered” (where you want to hide the secret messages) and the graphic which means “writing” (text). In this paper, a new Steganography technique is presented, implemented and analyzed. The proposed method hides the secret message based on searchin...

Improved Image Quality in Phased Array Ultrasound by Deconvolution

High contrast and resolution in phased array ultrasonic images are of importance for accurate evaluation. The spread of the ultrasonic beam is one cause of the images being unsharp. One technique for reducing the influence of the beam spread, and thereby improving the image quality, is by deconvolving the data with the point spread function of the ultrasonic beam. By assuming that the material ...

Modern Liver Imaging Techniques – A New Era in Liver Ultrasound

Ultrasound: new techniques and imaging in iatrogenic conditions

ugust’s issue represents a new dawn for the AJUM. This is the first time the AJUM has been filled from start to finish with original scientific work. This represents a significant move towards eventual Medline listing. The Editorial Board is pleased to present seven original manuscripts in total which present on an array of subjects including saline sonovaginography to measure the rectovaginal ...

Image Quality Assessment Techniques

Image Quality assessment plays an important role in various image processing applications. It is still an active field of research. A great deal of effort has been made in recent years to develop objective image quality metrics that correlate well with perceived human quality measurement or subjective methods. Most full reference(FR) technique were derived based on pixel to pixel error such as ...
