Imaging and Alignment for Image-Guided Radiation Therapy

Journal of Clinical Oncology, 2007
Image-guided radiation therapy is an exciting new area that focuses heavily on the potential benefit of advanced imaging and image registration to improve precision, thus limiting morbidity and potentially allowing for safe delivery of increased dose.

VLTI image alignment monitoring

SPIE Proceedings, 2003
In its current configuration, the VLT Interferometer (VLTI) combines the light collected by two telescopes and directs it towards the commissioning instrument called VINCI. In an interferometer, the optical path ranging from a telescope to the point where beams are combined is referred as an arm of the interferometer.

Automatic alignment of radionuclide images

Physics in Medicine & Biology, 1982
The variability of the position, dimensions and orientation of a radionuclide image within the field of view of a gamma camera hampers attempts to analyse the image numerically. A method is described for using a set of training images of a particular type, in this case right lateral brain images, to define the likely variations in the position ...

Alignment of X-ray bone images

2014 X International Symposium on Telecommunications (BIHTEL), 2014
Switching to digital technology from analog brought many changes, especially in storage of digital X-ray images. In cases of multiple fractures or need for imaging of a large area it is necessary to make more than one X-ray image for the observed part of body. This is often the case with spine, legs and arms.

Fast Fingerprint Image Alignment

2012
Fingerprint is one of the various modalities used in biometrics for authentication. An important issue, when designing a fingerprint–based biometric system / application is alignment of fingerprint images before feature extraction and matching. In this paper we present fingerprint alignment algorithm based on Principal Component Analysis (PCA).

Asymmetric gradient-based image alignment

2009 IEEE International Conference on Acoustics, Speech and Signal Processing, 2009
A new method for template-based image alignment is presented in this paper. A gradient-based optimization of motion compensated error difference is addressed to solve the image alignment problem. Its novelty lies in the minimized error, which considers the bi-directional compensation of the reference template and the current image onto each other in a ...

Aligning Islamic Spirituality to Medical Imaging

Journal of Religion and Health, 2015
This paper attempts to conceptualize Islamic spirituality in medical imaging that deals with the humanistic and technical dimensions. It begins with establishing an understanding concerning spirituality, an area that now accepted as part of patient-centred care.

Efficient alignment of fingerprint images

Object recognition supported by user interaction for service robots, 2003
Fingerprint matching is a common technique for biometric authentication. Solid state sensors for fingerprint recognition are used in small sized embedded systems. The size of these sensors makes it necessary to store several impressions of the same finger.

Aligning images with multiple objectives

2008 IEEE Congress on Evolutionary Computation (IEEE World Congress on Computational Intelligence), 2008
Most high level interpretation tasks in image analysis rely on image registration (alignment) process. Basically, image registration consists in finding the geometric transformation that best aligns two or several images. In this paper, we focus on mono-modality image alignment. The core task to do in this case is to put into correspondence two sets of
