摘要：
The present invention relates to an absorbable implant materialcomposed of magnesium or a magnesium alloy and to a method for theproduction thereof. A disadvantage of known absorbable implants isthat the position of the implant during the medical implantationprocedure and immediately thereafter can only be tracked by meansof X-ray examinations. According to the invention, what is providedis an absorbable implant material comprising homogeneouslydistributed Fe-doped nanodiamonds in a matrix composed ofmagnesium or a magnesium alloy. Fe-doped nanodiamonds are harmlessto organisms. This allows the detection of the implant material inthe blood plasma of the patient by means of magnetic resonanceimaging.According to the invention, the absorbable implant materialaccording to the invention is produced by a method in whichmagnesium or a magnesium alloy is melted, Fe-doped nanodiamondsare added to the melt, and the melt composed of magnesium or amagnesium alloy that has been provided with Fe-doped nanodiamondsis subjected to an ultrasound treatment.
