The paper reviews the methods of digital imaging for photogrammetric purposes. Currently, two architectures compete with each other: the full frame CCD array and the linear array CCD. It seems, that in a long term the full frame will overcome the deficiencies of low spatial resolution and small image format. But it is no question that for the time being three-line imaging is the leading concept...

Structural health monitoring of plate like structures, using transducer arrays located suitably on the structure, finds applications in monitoring aerospace structures. These plates are anisotropic, with wave propagation properties varying with direction. Thus any technique for imaging this plate structure needs to take this into account. In this paper, a phased addition reconstruction algorith...

Introduction: In coronary MRA signal-to-noise ratio (SNR) is of primary concern as it limits the achievable spatial resolution for a given, tolerable scan time. One approach to increase the base SNR has been the design and application of multi-element coil arrays featuring up to 128 independent receive channels [1]. With 32element coil arrays becoming standard for cardiac imaging [2], attention...

The geometric calibration of a spaceborne thermal-infrared camera with a high spatial resolution and wide coverage can set benchmarks for providing an accurate geographical coordinate for the retrieval of land surface temperature. The practice of using linear array whiskbroom Charge-Coupled Device (CCD) arrays to image the Earth can help get thermal-infrared images of a large breadth with high ...

Photoacoustic imaging (PAI) is an emerging biomedical imaging technology, which can potentially be used in the clinic to preoperatively measure melanoma thickness and guide biopsy depth and sample location. We recruited 27 patients with pigmented cutaneous lesions suspicious for melanoma to test the feasibility of a handheld linear-array photoacoustic probe in imaging lesion architecture and me...

Abstract. In this paper we consider narrow band, active array imaging of weak localized scatterers when only the intensities are recorded at an array with N transducers. We consider that the medium is homogeneous and, hence, wave propagation is fully coherent. This work is an extension of our previous paper [21] where we showed that using linear combinations of intensityonly measurements, obtai...

Despite the technical advances in radiological imaging modalities that have occurred in recent years in detecting foreign bodies like wood and plastics, they are not very often relied upon. Five of the six cases reported below seen over a period of 6 months, had a delayed presentation and ultrasound was found to be very useful in detecting and planning the treatment. The author strongly recomme...

Introduction:  The  success  of  hyperthermia  depends  on  the  accuracy  of  the  temperature  monitoring in the tumor and the surrounding normal tissue. In this study, the temperature changes  were determined by computing the speckle displacement in the ultrasound digital images. Speckle  tracking algorithm was used to compute the displacement.  Materials and Methods: The experiment was perf...
