The Application of Use Case Modeling in Designing Medical Imaging Information Systems

Table 3

Use case modeling characteristics and operational functions in medical imaging information systems.

N.	“Use case modeling” characteristics	Operational functions
1	A very realistic method for the patients, users and analyzers to have an accurate viewpoint about their own system	(i) Establishing a better correlation between medical imaging information system users, analyzers and developers.; (ii) Studying the weaknesses and strengths of the system.
2	Determining the operation framework and protocols	(i) Determining operation language specified conditions (in codes).; (ii) Defining operation exceptions.; (iii) Defining operation scale and time.; (iv) Defining concurrency several control processing.; (v) Defining conditions before and after the operation
3	Frequent relations between the units during data flow and health system processes	(i) Objects can be used again in designing medical imaging information systems.; (ii) The advantages of having an integrated system.
4	Classes can be used as standard patterns	(i) Redundancy reduction.; (ii) Setting new classes quickly.; (iii) Developing standards and their compatibility.; (iv) Easy support of the exceptions operation may face.
5	Designing the communication and information diagram of the system and parameters	(i) Exchange of information between patients and service providers.; (ii) Presenting a clear image of communication and information processes.; (iii) Determining performed operations in each time stage.; (iv) Determining the factor acting on the system.; (v) Determining the range of the project being implemented.; (vi) Having a basic mentality of the forgotten activities
6	Possibility of the information system users and analyzers concentration on the manner of the users interaction for performing an individual activity with the system	(i) Better understanding and collecting the requirements of system user.; (ii) Better relation between system user and analyzer.; (iii) Preparing the ground for better exchange of information between user and system analyzer.
7	Examining the involved information systems from different views	(i) Better understanding and modeling of the users requirements.; (ii) More complete recording of medical imaging information system.
8	Constant evaluation, control and filtering of the related information system	(i) Adopting the real requirements the users.; (ii) Medical imaging information system with high-quality.
