Dynamic tests of multi-detector radiometric system on central blood circulation phantom

Phantoms of organs and biological systems are widely used for verification of radioisotope protocols. The construction and operation of the heart and circulation phantom is described. The present model was designed for experimental testing of multi-detector radiometric system, prototype of which was designed in Ural Federal University as an extension and alternative to Anger camera and single-photon-emission tomography radionuclide diagnostics. The model represents vital dynamic properties of the single-chamber pulsing heart and circulation, featuring adjustable heart rate, blood volume, ejection fraction and flowrate. The trial experiments were performed with 99m Tc-pertechnetate to obtain time-activity curves and the ejection fraction was thus measured basing on first-pass radio angiography technique. © Published under licence by IOP Publishing Ltd

Morphometric parameters of the internal organs of a water deer (

The paper presents the results of a morphometric study of the internal organs of a water deer (Hydropotes inermis Swinhoe 1870) found in the southern part of the Primorsky Krai of Russia. For the first time, the linear and weight parameters were determined, the morphological features of the internal organs of the water deer were described
