Atraumatic CBF Measurement With the Scintillation Camera

A scintillation camera connected to a dedicated computer system was employed for atraumatic CBF measurements in 43 patients after intravenous injection of 35 to 55 raCi Xe in saline solution. To validate this method results were compared to flow values in the same patients measured after intracarotid Xe injection. While the correlation between i.e. and i.v. values was not satisfactory when a hi...

Camera Calibration Technique using Robust

In this paper we present an algorithm for camera and projector calibration of the liquid crystal range nder using space encoding technique. Because the accuracy of calibration is aaected by noises, and the variation of position or scale of the reference object in the input images, the least-median-of-squares technique is used in our approach, instead of the conventional least squares method. Th...

Clinical Significance of Scintillation Camera Electronics

Recent advances in collimator design and detector size, combined with radiopharmaceuticals having high photon yield, have resulted in diagnostic tests that may deliver photon fluxes in excess of the levels at which scintillation cameras can process the data. Moreover, these high rates of photon input may im pair certain parameters of image quality (1 ,2). For certain diagnostic tests, such as c...
