The role of the radiotherapy technologist in gamma knife radiosurgery within a multidisciplinary team: the Lausanne experience

Objective: Integration of the radiotherapy technologist "know-how" in the Gamma Knife treatment processMaterials and Methods: Gamma Knife (GK) treatments started in July 2010 at the GK Center in C.H.U.V. with the Leksell Gamma KnifeR Perfexion?(Elekta AB, Sweden). The multidisciplinary GK team involves neurosurgeons, radio-oncologists, physicists, neuroradiologists, nurses and technologists, aiming at a full integration for optimal patient management.Results: Between July and December 2010, 60 patients have been treated. Required stereotactic imaging involves IRM, CT scan (and angiography for AVM). All the steps in the treatment process (Leksell coordinate frame fixation, imaging, planning, treatment) are supervised by the members of the multidisciplinary team. In our experience, radiotherapy technologist (RTT) have acquired an important role in the multidisciplinary team communication and integration. Specifically, the RTT are responsible of: supervision of the image acquisition, performing the Gamma Knife unit control tests, patient setup, and patient surveillance during treatment.Conclusion: RTT have a fundamental role in the communication within the team, between the team and the patient and also to assure the patient security. Our experience shows that it is possible and required to involve RTT in all steps of the GK treatment process, to guarantee the best GK treatment possible.

De la conception à la pratique Reconfiguration d'un dispositif de formation des enseignants aux technologies de l'information et de la communication.

Constatant que la formation des enseignants aux technologies de l'information et de la communication (TIC) pose des problèmes spécifiques, cet article a pour but d'engager une réflexion sur ce thème. Nos réflexions s'appuient sur une expérience de formation réalisée dans 23 écoles professionnelles suisses engagées dans un programme national de soutien à l'utilisation pédagogique des TIC. L'article décrit la manière dont le dispositif de formation prévu a été mis en pratique, les difficultés auxquelles il a donné lieu et les réponses que les acteurs ont élaborées pour faire face à ces difficultés. Nous montrons qu'une analyse du déroulement effectif d'un dispositif de formation et des transformations qu'il subit constitue un élément essentiel pour orienter les futures actions de formation et penser la place des apprenants dans un dispositif de formation.

Aptitudes communicationnelles et formations à la communication en oncologie : Discussion critique

Cet article consiste en une discussion critique de la question de la communication en matière de prise en charge du patient atteint de cancer et de l'enseignement des aptitudes communicationnelles en oncologie. Nous avons d'abord essayé de définir les contours de ce qu'est (ou devrait être) une communication adéquate en oncologie, pour ensuite aborder les concepts sous-tendant les formations à la communication dans ce domaine, le problème des recommandations d'experts et du type dominant d'évaluation se rapportant à ces formations ainsi que les contenus enseignés et ainsi véhiculés.

Integration of Bridge Damage Detection Concepts and Components (3 volumes), TR-636, 2013

This work is divided into three volumes: Volume I: Strain-Based Damage Detection; Volume II: Acceleration-Based Damage Detection; Volume III: Wireless Bridge Monitoring Hardware. Volume I: In this work, a previously-developed structural health monitoring (SHM) system was advanced toward a ready-for-implementation system. Improvements were made with respect to automated data reduction/analysis, data acquisition hardware, sensor types, and communication network architecture. The statistical damage-detection tool, control-chart-based damage-detection methodologies, were further investigated and advanced. For the validation of the damage-detection approaches, strain data were obtained from a sacrificial specimen attached to the previously-utilized US 30 Bridge over the South Skunk River (in Ames, Iowa), which had simulated damage,. To provide for an enhanced ability to detect changes in the behavior of the structural system, various control chart rules were evaluated. False indications and true indications were studied to compare the damage detection ability in regard to each methodology and each control chart rule. An autonomous software program called Bridge Engineering Center Assessment Software (BECAS) was developed to control all aspects of the damage detection processes. BECAS requires no user intervention after initial configuration and training. Volume II: In this work, a previously developed structural health monitoring (SHM) system was advanced toward a ready-for-implementation system. Improvements were made with respect to automated data reduction/analysis, data acquisition hardware, sensor types, and communication network architecture. The objective of this part of the project was to validate/integrate a vibration-based damage-detection algorithm with the strain-based methodology formulated by the Iowa State University Bridge Engineering Center. This report volume (Volume II) presents the use of vibration-based damage-detection approaches as local methods to quantify damage at critical areas in structures. Acceleration data were collected and analyzed to evaluate the relationships between sensors and with changes in environmental conditions. A sacrificial specimen was investigated to verify the damage-detection capabilities and this volume presents a transmissibility concept and damage-detection algorithm that show potential to sense local changes in the dynamic stiffness between points across a joint of a real structure. The validation and integration of the vibration-based and strain-based damage-detection methodologies will add significant value to Iowa’s current and future bridge maintenance, planning, and management Volume III: In this work, a previously developed structural health monitoring (SHM) system was advanced toward a ready-for-implementation system. Improvements were made with respect to automated data reduction/analysis, data acquisition hardware, sensor types, and communication network architecture. This report volume (Volume III) summarizes the energy harvesting techniques and prototype development for a bridge monitoring system that uses wireless sensors. The wireless sensor nodes are used to collect strain measurements at critical locations on a bridge. The bridge monitoring hardware system consists of a base station and multiple self-powered wireless sensor nodes. The base station is responsible for the synchronization of data sampling on all nodes and data aggregation. Each wireless sensor node include a sensing element, a processing and wireless communication module, and an energy harvesting module. The hardware prototype for a wireless bridge monitoring system was developed and tested on the US 30 Bridge over the South Skunk River in Ames, Iowa. The functions and performance of the developed system, including strain data, energy harvesting capacity, and wireless transmission quality, were studied and are covered in this volume.

The impact of communication skills training in oncology: a linguistic analysis.

This study aimed to investigate the impact of a communication skills training (CST) in oncology on clinicians' linguistic strategies. A verbal communication analysis software (Logiciel d'Analyse de la Communication Verbale) was used to compare simulated patients interviews with oncology clinicians who participated in CST (N = 57) (pre/post with a 6-month interval) with a control group of oncology clinicians who did not (N = 56) (T1/T2 with a 6-month interval). A significant improvement of linguistic strategies related to biomedical, psychological and social issues was observed. Analysis of linguistic aspects of videotaped interviews might become in the future a part of individualised feedback in CST and utilised as a marker for an evaluation of training.
