CQUS

Ultrasound equipment quality control

In several technology application areas, various quality control (QC) procedures are utilized. Such procedures evaluate the general quality of the equipment used in many clinical procedures, for both diagnoses and treatments. Many diagnostic instruments in radiology and radiotherapy are routinely analyzed and tested by several QC procedures, and maintenance reports are provided to ensure the quality of the instruments.

Several research groups have jointly formulated and implemented QC practices for B-mode ultrasonography in Brazil. Several normative works have been conducted for the international establishment of QC procedures. Even with advances in the field, there are still major barriers to their application in Brazil. Typically, the QC process, including data recording and other paperwork, is performed entirely by hand, which increases the time required for the QC data acquisition and analysis and the susceptibility of human error. Additionally, the lost machine time could be used to diagnose patients, and the generated paperwork presents storage issues for the future analyses of the ultrasound equipment. A few efforts have been made to improve the data acquisition and semi-automatic processing. However, an efficient approach to basic QC tests in B-mode ultrasonography is lacking.

For this reason, CQUS was created to assist, as a computational system, the QC diagnostics of B-mode ultrasonography. The use of computational programs dedicated to the various QC tests is a promising alternative to reducing the required time for the procedures and guarantees the standardization of QC results.
