Dunlee sponsored such an independent study which was conducted by hospital physicist Professor Robert L. Dixon, Ph.D and president of Radiological Physics Consultants, Inc. and past president of the American Association of Physicists in Medicine, to measure and evaluate the use of Dunlee tubes on GE CT systems. The objective was to determine if Dunlee X-ray tubes delivered an equivalent dose within the published GE specifications for its own CT scanners equipped with comparable X-ray tubes including both the GE VCT* and GE LightSpeed-16* scanners.
Through this methodical and statistically rigorous independent evaluation, it was determined that these replacement X-ray tubes are well-matched to that of GE in terms of the dose delivered by each to the head and body dosimetry phantoms for the standard CTDI scan techniques as published by GE in its Technical Manual.
As doctors and scientists are highly data-driven and expect verifiable evidence of any claim, replacement part manufacturers and other stakeholders should be eager to obtain independent verification of replacement part quality and technical specification matching and performance. That is particularly important where diagnostic quality and patient safety hang in the balance, such as in the replacement of CT scanner X-ray tubes that must measure up- literally- in every respect.
