Breast cancer is the first cause of mortality of women aged 55 to 75. It is only in the last decade that breast anatomy has started being seriously considered by pioneer radiologists such as M. Stravos, M. Teboul and D. Amy. Indeed, it is now widely admitted that 90% cancer lesions and mainly all the specific diseases of the breast initiate from the epithelium and develop first in the...

Three dimensional Optical Diffusion Tomography allows in vivo studies of tumour life without any stress or damage for the animal. We present hereafter theoretical and experimental results obtained with the system developed in our laboratory on phantoms and mice. The experimental set-up consists of a laser source (690nm) coupled to a motorized stage, a CCD camera and a tank to...

Fluorescence tomography modality is envisioned to be an economical functional quantitative measure and could benefit to the pharmacological industry for experiments on small animal. It consists in injecting cancer specific fluorescence marker and reconstructing the fluorescence by using the fluorescence tomography technique. The reconstructed fluorescence can be used as a marker of the...

Recent developments in the field of micro-CT imaging have revolutionized the ability to examine in vivo the living experimental animal models such as mouse with acceptable spatial resolution according to the animal size. One of the main requirements of in vivo imaging for biological researchers is a reduced acquisition and reconstruction time for screening purposes. We previously...

In previous works we have presented our multiplexing multi-pinhole SPECT imaging technique and its extensive applications in small-animal molecular imaging. SPECT combined with X-ray CT introduces anatomical information and improves acquisition (helps define axial region of interest), reconstruction (attenuation correction) and data analysis (aids segmentation). In this work we present a...

In Particle Induced X-ray Emission (PIXE), the production cross sections of characteristic X-rays are very large in comparison to those of continuous X-rays, which when integrated over the detector resolution are typically 3 orders of magnitude smaller. This feature is quite different from the case of electron bombardment, where the electron bremsstrahlung contributes predominantly to...

Imaging of soft tissue demands high sensitivity and contrast enhancing techniques in order to reliably detect and resolve structures and patterns of small size and of similar atomic composition. For these purposes, traditional X–ray transmission–based radiography is limited by the low and homogenous absorption of X–rays in soft tissue. Phase shift contrast imaging can bring additional...

Partial k-space acquisition is a subject of great interest in MRI. This type of acquisition usually consists of, in addition to the positive half of k -space, acquiring a number of negative frequencies beyond the k-space center, thus requiring an increase of acquisition time. Furthermore, the quality of the reconstructed image depends on the number of negative frequencies acquired. To...

Recently, the development of combined TEP/CT imaging systems led to a rapid expansion of this technique in clinical routine. Like for clinical routine, the development of dedicated PET scanners and micro- CT scanners for small animals encourages to have these two imaging modalities embedded on a common gantry. However, the juxtaposition of both modalities does not allow for extrapolating...
