This paper presents bent crystals obtained by low energy plasma enhanced chemical vapour deposition technique, which could be further improved for medical applications to focus gamma rays. Medical imaging plays an important role in the field of nuclear medicine and the use of bent crystals to focus energetic gamma rays used for imaging of radioactivity in the human body is our interest. An innovative technique to obtain curved crystals is proposed in this work. Surface profilometry measurements were done to find the curvature of curved crystals
