Breast cancer is the most prevalent cancer among women. Early diagnosis of breast cancer increases the chance for cure by 90%. “Berta” is a prototype system developed in the Department of Bio-medical Engineering, and it is used for 3-dimensional imaging, for diagnosis and for treatment of breast cancer. There are some unique requirements for the BERTA treatment bed system, partly resulting from the technology and partly from the system structure. In this thesis, instructions for designing and engineering of BERTA’s - treatment bed system, were formulated. The constraints and requirements of the environment and users were explored. In addition to the general requirements for medical equipment other factors which are specific to this application and system were considered when designing and engineering it. In order to understand the system’s mode of operation and to define requirements and constraints, we performed a detailed review of the settings in which the system is used, its users, the diagnosis and treatment/surgery processes as they occur, and various maintenance stages of the system. An analysis of the following 4 scenarios for using the system was done:
Each one of the scenarios was divided into tasks and subtasks. An analysis of possible problems was prepared for each stage of each task and subtask, and solutions were suggested for each of these problems. By analyzing the constraints, the tasks and the problems, we could define the requirements for the treatment bed, which turned into instructions for designing and engineering the bed. Following an analysis of the existing componenets and considering our own product requirements, three configurations for new designs of the treatment bed were presented, an analysis of each one was performed, and a preferred configuration was chosen for further development. The treatment bed designed in the project combines all the benefits of a modular bed with adjustable elements, and is constructed of two separate parts, mobile and static, this enables resetting the system for comparing the results of different scans. The chosen concept which is based on dividing the bed into two parts can easily help in expanding the designed bed for additional medical applications.
