It is an object of the invention to improve the radiotherapy workflow. This object is achieved by a medical product configured to be used for image based radiotherapy planning. The medical product is configured to be connected to:—;a medical imaging system configured for acquiring medical images of a patient;—;a contour module configured for segmenting one or more contours based on one or more of the medical images and;—;a treatment planning system configured for calculating a radiotherapy plan based on the one or more contours. The medical product comprises a user interface configured to receive user input on a treatment target in the patient and to receive user input on a treatment technique. The medical product is configured to execute a data object readable to the medical imaging system, the contour module and the treatment planning system on the basis of the user input and wherein the data object comprises computer readable instructions for these systems and modules and wherein the systems and modules are configured to contribute to the creation of the radiotherapy plan based on the user input.
