Image-based Stereo Visual Servoing: 2d Vs 3d Features

This paper presents a visual servoing approach based on stereo vision. The pair of cameras is mounted on the end-e ector of the manipulator arm. Theoretical dev elopments are presented using either raw pixel coordinates, or 3D coordinates estimated from image features. No geometrical model is needed. The experimental setup is challenging: large rotations are involved, images are noisy ,and came...

A comparison of 2D and 3D kidney absorbed dose measures in patients receiving 177Lu-DOTATATE

Objective(s): To investigate and compare quantitative accuracy of kidney absorbed dose measures made from both 2D and 3D imaging in patients receiving 177LuDOTATATE (Lutate) for treatment of neuroendocrine tumours (NETs). Methods: Patients receiving Lutate therapy underwent both whole body planar imaging and SPECT/CT imaging over the kidneys at time points 0.5, 4, 24, and 96-120 hours after inj...

3D MRI gel dosimetry based on image intensity (A new approach)

Background: Since 1984 MRI gel dosimetry has been introduced as a potential technique for 3D dosimetry. Most of the studies have measured R1 (1/T1) or R2 (1/T2) properties of the gel depending on the gel type. We have studied image intensity change in the Fricke gel by different MRI protocols. Materials and Methods: Gel Dosimeters contain 0.4 mM ferrous sulphate, 1 mM NaCl, 50 mM H2SO4 and 1% b...

Evaluation of right ventricular volume and function by 2D and 3D echocardiography compared to MRI.

AIMS Radionuclide techniques, and recently MRI, have been used for clinical evaluation of right ventricular (RV) volumes function (RVEF) and volumes; but with the introduction of 3D echocardiography, new echocardiographic possibilities for RV evaluation independent of geometrical assumptions have emerged. This study compared classic and new echocardiographic and radionuclide estimates, includin...

3D/2D object-based coding of head MRI data

We propose a coding system featuring 3D encoding/2D decoding object-based functionalities. Any object of any 2D image of the dataset can be recovered at a finely graded up to lossless quality. Compression is improved by exploiting the full correlation among data samples by means of 3D DWT. A swift access to 2D images is obtained by enabling 2D decoding. Given the index of the image of interest ...
