Abstract: A patient pallet has two sides, a proximal end and a distal end. The patient pallet is horizontally elongated and is positioned to support a human patient with the patient's body axis horizontal. The pallet is supported by a pedestal. The pedestal is vertically moveable so that the patient may be raised and lowered with respect to the floor. The pedestal receives the patient pallet so that the pallet can slide horizontally, parallel to the floor. A pallet support is horizontally spaced from the pedestal and is so located that the distal end of the patient pallet can be supported by the pallet support when the patient pallet is slid horizontally. In this way, the patient pallet is either supported by the pedestal alone or by the pedestal and the pallet support. In the latter instance, the patient pallet bridges between the pedestal and pallet support. Left and right horizontally elongated arm rests are provided.

Abstract: A method and apparatus for determining crystallization properties, such as the particle kinetics, of urine. A first feed solution is formulated as including synthetic urine plus an aliquot of natural urine. A second feed solution which includes synthetic urine is also formulated. The two feed solutions are combined in a continuous crystallizer and the particle densities or crystal populations of the contents of the crystallizer are measured. Finally, the particle kinetics, such as the nucleation and growth rate of the crystals, are calculated as a function of the measured particle densities. In the preferred embodiment, the first and second feed solutions each comprise synthetic urine plus an aliquot of natural urine, with the natural urine preferably having a concentration in the range of about three percent to thirty percent of the total.
