Real-time clinical applications such as robotic lung surgery, tumor localization, atelectasis diagnosis, tumor motion prediction for radiation therapy of lung cancer, or surgery training are in need of biomechanical models of lungs, not necessarily highly accurate, but with good computational properties. These properties can include one or several of the following: low computation time, low memory resource requirement, a low number of parameters, and ease of parameter identification in real-time. Among the numerous existing models of lung parenchyma, some may be well suited for real-time applications; however, they should be extensively assessed against both accuracy and computational efficiency criteria to make an informed choice depending on the requirements of the application.

Diffraction calculations in few-bit formats, such as single-precision floating-point and fixed-point numbers, are important because they yield faster calculations and lower memory usage. However, these methods suffer from low accuracy owing to the loss of trailing digits. Fresnel diffraction is widely known to prevent the loss of trailing digits.

There are still unanswered questions about the safety of fragrances. In this conference paper, fragrance allergy will be considered in the context of a wider discussion concerning the prevalence and causes of contact dermatitis. No criteria for a reliable diagnosis of 'contact dermatitis' are available.

Background: There are still open questions about the safety of fragrances.
Objectives: To evaluate the evidence concerning the frequency of contact dermatitis to fragrances in the general population and selected subgroups and the risk factors for sensitization and clinical manifestations.
Methods: Review of published data.
