Volumetric 3D displays are frequently purported to lack the ability to reconstruct scenes with viewer-position-dependent effects such as occlusion. To counter these claims, a swept-screen 198-view horizontal-parallax-only 3D display is reported here that is capable of viewer-position-dependent effects. A digital projector illuminates a rotating vertical diffuser with a series of multiperspectiv...

Objective: The purpose of this study was to determine if volume-rendered three-dimensional displays could improve the accuracy of reporting renal cortical scars in patients imaged with mTc dimercaptosuccinic acid (DMSA). Methods: We compared volume-rendered three-dimensional displays of SPECT data for 20 patients, with a total of 37 kidneys, with SPECT data displayed as transaxial, coronal and ...

UNLABELLED Two-dimensional SPECT display and three methods for integrated visualization of SPECT and MRI patient data are evaluated in a multiobserver study to determine whether localization of functional data can be improved by adding anatomical information to the display. METHODS SPECT and MRI data of 30 patients were gathered and presented using four types of display: one of SPECT in isola...

The present paper deals with the generation of Love waves in a layer of finite thickness over an initially stressed heterogeneous semi-infinite media. The rigidity and density of the layer are functions of temperature, i.e. they are temperature dependent.  The lower substratum is an initially stressed medium and its rigidity and density vary linearly with the depth. The frequency relation of Lo...

OBJECTIVE Stereoscopic vision display technology has been shown to be a useful tool in image-guided surgical interventions. However, the concept has not been applied to 3-dimensional echocardiography-guided cardiac procedures. We evaluated stereoscopic vision display as an aid for intracardiac navigation during 3-dimensional echocardiography-guided beating-heart surgery in a model of atrial sep...
