  • Diagnostic X-rays

    A diagnostic X-ray is the oldest and most common medical radiology procedure. Radiologists use X-rays to help diagnose disease or injury inside your body. A machine directs a small, carefully calculated amount of radiation toward a specific part of the body to produce an image on a film on the other side of the body. Radiologists study the X-ray images to detect and diagnose disease or injury.

  • CT dosage

    Computed Tomography (CT) is currently one of the major contributors to the collective population radiation dose due to the increasing popularity of CT examinations as a non-invasive diagnostic tool. The evolution of CT scanner technology has turned their use from specialized into routine examination. More due diligence is required due to the high radiation dose of CT.

  • Where to from here?

    It is of the utmost importance that both clinical justification as well as technical optimization are implemented to maintain a high benefit to risk ratio. Solid interdisciplinary partnerships and research endeavours between clinical specialists and technology engineers will help to fast track developments in this area.

Masters topic:

Ventilation System Design for Use in Assisting Premature Infant Respiration Studies

Details:

This Masters' thesis presents a new ventilation device developed for pulmonary ventilation studies. The device utilises the recently developed design of a dual chamber system, with separate systems controlling the peak inspiratory pressure and end-expiratory pressure; however, improves on the previous design by incorporating a novel microprocessor controlled pneumatic bleed system to quickly and accurately control the pressures within the chambers, as well as maintaining a stable and consistent pressure profile. The new design includes a highly customisable timing control module to synchronise with image acquisition systems, which may be utilised for the control of other devices such as data acquisition devices or medical equipment. The new device has been assessed against two commercially available small animal ventilators in response to changes in ventilation parameters such as inspiration time, as well as peak inspiratory and end-expiratory pressures. The results show the new ventilator to be more stable, quick, accurate and consistent over all ventilation strategies in comparison to the other devices. This ventilator serves to increase the capacity of research within the neonatal respiration team at Monash University.
