Image Quality Characteristics of Handheld Display Devices for Medical Imaging

Handheld devices such as mobile phones and tablet computers have become widespread with thousands of available software applications. Recently, handhelds are being proposed as part of medical imaging solutions, especially in emergency medicine, where immediate consultation is required. However, handheld devices differ significantly from medical workstation displays in terms of display character...

Radiology on handheld devices: image display, manipulation, and PACS integration issues.

Handheld personal digital assistants (PDAs) have undergone continuous and substantial improvements in hardware and graphics capabilities, making them a compelling platform for novel developments in teleradiology. The latest PDAs have processor speeds of up to 400 MHz and storage capacities of up to 80 Gbytes with memory expansion methods. A Digital Imaging and Communications in Medicine (DICOM)...

Image Retargeting for Small Display Devices

In this paper, we propose a novel image importance model for image retargeting. The most widely used image importance model in existing image retargeting methods is L1-norm or L2-norm of gradient magnitude. It works well under non-complex environment. However, the gradient magnitude based image importance model often leads to severe visual distortions when the scene is cluttered or the backgrou...

Photonic Devices for Imaging, Display, and Storage

Electronic and electro-optic devices are frequently used to display images obtained from the computer processing of data. Images, or digital pictures, are generally two-dimensional data structures that convey spatial information to the viewer. Images are collected through various means, from digital cameras to laser radar scanning systems and, once stored in a computer, can be manipulated mathe...
