Commissioned by the DraxImage biotechnological firm to design an automated quality control system to be integrated at the end of the production line of a specific drug, a group of students in mechanical engineering at McGill University brilliantly took up the challenge of putting engineering at the service of health. Called Radioactive Brachyseeds (in the form of a mini-capsule measuring 4.4 mm by 0.8 mm), the drug is the latest and most efficient protection against prostate cancer. Injected directly into the organ through the rectum using a special syringe, the geometry of the particles must be perfect. If not, the syringe can become blocked and cause enormous displeasure for the patient. As the demand has called for an increase in the production of this drug, human inspection is no longer sufficient. Using an analogical camera and the LabView computer program, the team of students succeeded in automating the visual inspection of the product while meeting their client’s specifications and requirements. Today, each sample can be meticulously analysed so as to purify the product and facilitate its administration.
