ABSTRACT This study aimed to obtain details regarding treatment planning techniques for lung stereotactic body radiation therapy (SBRT) employed at each institution in Japan by using a questionnaire survey. An Internet questionnaire survey on SBRT procedures performed in 2016 was conducted by the QA/QC committee of the Japan Society of Medical Physics from April to June 2017. The questionnaire assessed two aspects: the environment for SBRT at each institution and the treatment planning techniques with and without respiratory motion management techniques (RMMT). Of the 309 evaluated responses, 218 institutions had performed SBRT. A total of 186 institutions performed SBRT without RMMT and 139 institutions performed SBRT with RMMT. When respiratory motion was ≥10 mm, 69 institutions applied RMMT. The leading RMMT were breath holding (77 institutions), respiratory gating (49 institutions) and real-time tumor tracking (11 institutions). The most frequently used irradiation technique was 3D conformal radiotherapy, which was used in 145 institutions without RMMT and 119 institutions with RMMT. Computed tomography (CT) images acquired under free breathing were mostly used for dose calculation for patients treated without RMMT. The usage ratio of IMRT/VMAT to SBRT is low in Japan, compared to elsewhere in the world (<20% vs ≥70%). Among the available dose calculation algorithms, superposition convolution was the most frequently used regardless of RMMT; however, 2% of institutions have not yet made heterogeneity corrections. In the prescription setting, about half of the institutions applied point prescriptions. The survey results revealed the most frequently used conditions, which may facilitate standardization of treatment techniques in lung SBRT.

Interpretive Process

Abstract. This article concerns the utility of ego psychoanalytic perspectives in Rorschach interpretation. Psychoanalytic ego psychology focuses on how people cope with events in their lives and how effectively they can meet challenges to their sense of well-being. The way people deal with experienced distress constitutes their defensive style and determines to a large extent what kind of person they are. Adequate defenses against anxiety promote comfortable and productive adjustment, whereas ineffective defenses typically cause adjustment difficulties and susceptibility to psychological disorders. In Rorschach assessment, the nature and effectiveness of a person’s defensive style can often be identified with a sequence analysis that integrates the structural, thematic, and behavioral features in the protocol. In particular, the sequential quality of responses, especially preceding and following instances of cognitive slippage, can help identify causes of upsetting concerns, defensive efforts to alleviating these concerns, and the adequacy of these defensive efforts in restoring equanimity. This interpretive process is illustrated with attention to implications for differential diagnosis and treatment planning in the Rorschach protocol of a 20-year-old suicidal woman.
