A method for loading a sample for imaging by an optical tomography system. A sample volume including at least one microscopic sample and a viscous fluid is coaxially loaded into a sample delivery tube. The sample volume is impelled through a focus cell into a capillary tube, where the capillary tube has a smaller crossectional area than the sample delivery tube, so that a reduced volume of the at least one microscopic sample and viscous fluid is constrained to a central region within the capillary tube.

Abstract:
A patient ventilator system provides a controllable flow and volume of a mixed inhalation gas to a patient, and receives exhaled gas from the patient. The ventilator system includes gas flow controllers that mix air and oxygen, and provide the mixture to the patient with a controllable inhalation cycle. The ventilator system monitors the resulting patient pressures and volume of gas exhaled by the patient, as necessary. Compressed air is provided to the gas controller in the event of an absence of an external gas supply by a compressor. A controller permits the user of the ventilator system to control ventilation mode, gas pressure, composition, and flow rate of the mixed gas with a single control knob.
