[en] A the design modification of the back seat frame used as a detector holder to support the operation of the integrated renograf has been done. Modification of the framework is done by replacing the structure that was hollow carbon steel 25 x 25 mm with a schedule 40 carbon steel pipe measuring 3/4 inch and with the hollow carbon steel the measures is 20 x 40 mm in thickness of 1.2 mm. Then performed the analysis using ANSYS software with loading parameters have been determined. The analysis showed that the maximum stress occurs at 1,7219 x 10⁸ Pa is still below the maximum limit of 2.4816 x 10⁸ Pa to be declared fit for use. With the proposed design modifications, the operation of the integrated renograf can be safe. (author)
