La tomographie d'emission est la principale methode d'imagerie fonctionnelle employee a l'heure actuelle pour le diagnostic medical. Malheureusement, encore actuellement, seules des informations qualitatives peuvent etre deduites des images obtenues

The paper presents a method involving fusion of anatomical data in the reconstruction applied to gated myocardial single photon emission computed tomography (SPECT). Anatomical data is introduced by using an active spline model of the thorax organs.

The objective of this study was to define the limits of echocardiography and to evaluate thoracic spiral CT angiography (TSCTA) for the diagnosis of pulmonary embolism (PE). One hundred twelve consecutive patients, hospitalised for suspected PE, were

The authors present the fusion of anatomical data as a method for improving the reconstruction in single photon emission computed tomography (SPECT). Anatomical data is used to deduce a parameterized model of organs in a reconstructed slice using spl

Thirty-five patients with suspected chronic osteomyelitis related to an orthopaedic device had 50 99Tcm-HMPAO-labelled leucocyte scans (LS). The scan appearances were compared with the bacteriological or clinical results and gave a sensitivity and sp

In this paper, gamma ray imaging using Fresnel zone plates is studied. We show that an M.T.F. can be associated with the coding—decoding process giving an evaluation of the final image quality. An experimental result corroborates the theoretical st

In coded aperture imaging applied to nuclear medicine, the ultimate limit is the Poisson noise of the gamma ray source. We show that the noise depends on the type of code. In particular we compare the signal to noise ratio between images obtained eit

A sequential method is developed to obtain a high resolution 3-D image distribution of the activity of a radioactive tracer. Two different types of reconstruction are presented. The first method, related to X or γ ray motion tomography, yields recon
