A graphical user interface for automatic image registration software designed for radiotherapy treatment planning.

Medical imaging forms a vital component of radiotherapy treatment planning and its evaluation. The integration of the useful data obtained from multiple imaging modalities for radiotherapy planning is achieved by image registration softwares. In radiotherapy planning systems, normally the computed tomography (CT) slices are kept as a standard upon which other modality images (magnetic resonance imaging [MRI], single photon emission computed tomography [SPECT], positron emission tomography [PET], etc.) are aligned--automatically or interactively. Following validation of successful registration, they are resampled and reformatted, as per the requirements. This paper defines the minimum requirements of automatic image registration software for 3-dimensional (3D) radiotherapy planning and describes the implementation of a suitable graphical user interface developed in Visual Basic (version 5). The automatic image registration (AIR) routines freely available from Dr. Roger P. Woods, UCLA, (USA) were used in this software. This software could be easily implemented and was easy to use for image processing suitable for radiotherapy planning systems.

siDirect: highly effective, target-specific siRNA design software for mammalian RNA interference.

siDirect (http://design.RNAi.jp/) is a web-based online software system for computing highly effective small interfering RNA (siRNA) sequences with maximum target-specificity for mammalian RNA interference (RNAi). Highly effective siRNA sequences are selected using novel guidelines that were established through an extensive study of the relationship between siRNA sequences and RNAi activity. Our efficient software avoids off-target gene silencing to enumerate potential cross-hybridization candidates that the widely used BLAST search may overlook. The website accepts an arbitrary sequence as input and quickly returns siRNA candidates, providing a wide scope of applications in mammalian RNAi, including systematic functional genomics and therapeutic gene silencing.

Designing Radiotherapy Software Components and Systems That Will Work Together.

The radiation treatment planning and delivery process requires that many different computerized data sources, software tools, and computer control systems be smoothly integrated. These include computer-controlled accelerators and new digital imaging modalities. At the same time, the applications themselves are becoming increasingly complex. In radiotherapy, the variety of components to integrate is much greater than in other areas of clinical medicine, growing out of more than a 30-year history of use of highly stylized traditional computer applications and many rigid conventions and practices associated with these computer programs. The introduction of new tools and computer-controlled equipment influenced the evolution of radiotherapy planning software, leading us to take a new look at how radiotherapy planning is done. Addressing and solving these integration problems as a serious research undertaking is vital to continued success in deploying computer applications for clinical use. New software design ideas such as object oriented design, behavioral abstraction and mediators can solve these problems. Our experience shows that the time and effort to build high-quality adaptable modular systems can be kept modest and within the reach of a small development team.

Development of a software for the design of custom-made hip prostheses using an open-source rapid application development environment.

The present work describes a technology transfer project called HIPCOM devoted to the re-engineering of the process used by a medical devices manufacturer to design custom-made hip prostheses. Although it started with insufficient support from the end-user management, a very tight scheduling and a moderate budget, the project developed into what is considered by all partners a success story. In particular, the development of the design software, called HIPCOM Interactive Design Environment (HIDE) was completed in a time shorter than any optimistic expectation. The software was quite stable since its first beta version, and once introduced at the user site it fully replaced the original procedure in less than two months. One year after the early adoption, more than 80 custom-made prostheses had been designed with HIDE and the user had reported only two bugs, both cosmetics. The scope of the present work was to report the development experience and to investigate the reasons for these positive results, with particular reference to the development procedure and the software architecture. The choice of TCL/TK as development language and the adoption of well-defined software architecture were found to be the success key factors. Other important determinants were found to be the adoption of an incremental software engineering strategy, well suited for small to medium projects and the presence in the development staff of a technology transfer expert.

A strategy for empowerment: the role of midwives in computer systems implementation.

The procurement and implementation of patient administration systems has been done on numerous occasions in the past. The Rotunda project however encompassed major bespoke clinical developments which were going to impact upon large clusters of midwives, and medical staff to a lesser extent. A broad based four level structured methodology was used to implement the project which is significantly ahead of schedule. This methodology together with its strengths and weaknesses is comprehensively discussed. The empowerment of midwives, their roles in systems analysis and design, software testing and organisational re-engineering is described. The importance of undertaking comprehensive computer training is highlighted and a compact 10 h information technology course coupled with ongoing educational and related activities which could be adopted by any organisation is documented. The seven deadly sins of project management are mapped out. An update on benefits realisation is provided. Gender issues are also discussed.

Content preauthoring: preparing medical imaging information for multimedia authoring and quizzing.

Recent advances in multimedia development software and related hardware have given professionals and nonprofessionals tremendous power and flexibility to create multimedia education and training programs. Nevertheless, content organization remains a key and often neglected component of program development. Content preauthoring puts findings, diagnoses, differential diagnoses, and other standard radiologic concepts into a format that fosters logical program layout, centralized remediation, record keeping, decreased data entry, a variety of user levels, easy addition of cases, and linkage to a question-generating program. The goal of content preauthoring is to organize radiologic material into a hierarchical or spreadsheet-based structure that provides a logical basis for software design. By separating content design from software authoring, both processes become more manageable. This approach is applicable to visually oriented topics that focus on identification. The highly structured, goal-oriented nature of the method makes it particularly suitable for newcomers to multimedia authoring.

[Software and hardware for computer equipment designed for psychophysiological examination].

Principles of designing software and hardware for new computer equipment for psychophysiological examination were elaborated on the basis of theoretical prerequisites and of analysis of the use of equipment manufactured serially for quantitation of indices of the human higher nervous activity (HNA). The hierarchic structuring of software and hardware enabled, through unification of solutions, the development of new modifications of two equipment sets: computer-based unit "Psihomat" KPFK-99 for psychophysiological examination and computer-based unit "STABILOTEST" ST-01 for the evaluation of the central nervous system by the stability parameters in maintaining the vertical posture. The units have new improved functional features and provide the users with new computer technologies for dealing with research and practical tasks related with examination of human HNA parameters in health and pathology.

Development and adoption of a simple nonpoint source pollution model for Port Phillip Bay, Australia.

New computing tools and approaches allow tailored development of software to meet the needs of environmental managers. The processes required for such tailoring fit well with adaptive management concepts where, as knowledge and system understanding develop among managers, the software can be developed or replaced to match. This paper reports on development and adoption of a simple nonpoint source pollution modeling tool, including technical aspects of data support for modeling and social aspects of software design. The software, named FILTER, used a unit load model to generate expected pollutant loads from subcatchments of Port Phillip Bay, Australia. Monitoring data were used for calibration to modify the delivery of generated pollutants to receiving waters. Spatial, tabular, and charting software components were used to provide alternative forms of output visualization. FILTER was developed using a process that resulted in manager-stakeholders taking responsibility for setting of model parameter values and operation of the user interface, thereby encouraging uptake. The inclusive development process, tailoring of the software to manager needs and styles of usage, and matching of model complexity to data and knowledge, resulted in a successful application that has become the current agreed system representation among disparate stakeholder organizations.

A novel approach to data collection in a case-control study of cancer and occupational exposures.

BACKGROUND: In community and hospital-based case-control studies, the occupational data collected in interviews are usually limited to responses to general questions asked of all study subjects. A procedure is described in which more detailed information can be collected in an efficient, standardized and systematic way. METHODS: A generic work history is initially collected from all subjects using a computer-assisted interview. The work history includes job title, type of business, job activities, materials and chemicals, and tools and equipment used. After responses are entered into the computer by the interviewer, the computer searches a synonym file to identify possible job-specific modules relevant to the reported job. The modules are detailed questionnaires that address specific jobs administered after obtaining the generic work history. The modules are used to ask questions about the work environment; sources of exposure; factors affecting the movement of the agent from the source to the subject, such as local exhaust ventilation; and individual and job characteristics. After the interview is completed, the work history and responses to the modules are sent electronically to an industrial hygienist who reviews the information using a custom-designed software package. Where ambiguities or contradictions occur in information reported by the respondent, or for jobs for which no module had been developed, the industrial hygienist generates up to 10 additional questions per job. These questions are sent back to the interviewer for administration of a short, second interview. CONCLUSIONS: These procedures, which are being successfully implemented in an on-going case-control study of brain tumours, should improve disease risk estimates over those derived from more traditional approaches to exposure assessment.

Workflow analysis and evidence-based medicine: towards integration of knowledge-based functions in hospital information systems.

The large extent and complexity of scientific evidence described in the concept of evidence-based medicine often overwhelms clinicians who want to apply best external evidence. Hospital Information Systems usually do not provide knowledge-based functions to support context-sensitive linking to external information sources. Knowledge-based components need specific data, which must be entered manually and should be well adapted to clinical environment to be accepted by clinicians. This paper describes a workflow-based approach to understand and visualize clinical reality as a preliminary to designing software applications, and possible starting points for further software development.
