[Radiomics for Molecular Classification and Treatment Strategy].
Abstract After the end of human genome project, the cost of genetic analysis has rapidly declined with the advancement of next-generation sequencers. In addition, the relationship between various diseases and genes has been clarified. Therefore, it is likely that genetic testing may be performed in daily clinical practice in the near future. In such background, a novel research 'radiomics' is spreading to offer a new viewpoint for the use of genotype in radiological field which has traditionally focused on the analysis of imaging phenotypes. Radiomics is applied to the molecular classification or treatment strateg...

[Dose and Radiation Quality Optimized Heavy-Ion Radiotherapy].
Abstract The biological effectiveness of charged-particle beams depends not only on dose but also on radiation quality. The radiation quality of charged-particle beams has been most commonly represented by the linear energy transfer (LET) in radiation biology studies. We investigated a new therapeutic technique of charged-particle therapy in which two or more ion species are delivered in one treatment session for optimizing the dose and LET distributions in a patient. We refer the therapeutic technique as an Intensity Modulated composite PArtiCle Therapy (IMPACT). Helium, carbon, oxygen and neon ions are considere...

Abstract In 2016, the American Association of Physicists in Medicine (AAPM) has published a report of task group (TG) 100 with a completely new concept, entitled "application of risk analysis methods to radiation therapy quality management." TG-100 proposed implementation of risk analysis in radiotherapy to prevent harmful radiotherapy accidents. In addition, it enables us to conduct efficient and effective quality management in not only advanced radiotherapy such as intensity-modulated radiotherapy and image-guided radiotherapy but also new technology in radiotherapy. It should be noted that treatment p...

[MRI Connecting Functions and Anatomy: A New Bridge for Radiotherapy].
Abstract Advances in medical devices have allowed the use of CT, MRI, and PET-CT for the diagnosis of tumors and the detailed evaluation of the extent of lesions. For several decades, CT has been established as the gold standard modality for the treatment planning of radiotherapy, while MRI has emerged as a tool to evaluate the functional characteristics of tumors without radiation exposure. To further optimize precision radiation therapy, we should consider how functional images can be used in the workflow for radiation therapy. In this regard, MRI, as a modality without the need for a contrast agent, may allow m...

[Nuclear Medicine for Optimized Treatment Strategy and Real-Time Therapy Imaging].
Abstract PET and SPECT provide us with information about biological quantitative values at localized area, even at the deep component of human. They usually have been used for diagnosis, but when combining with radiotherapy, PET and SPECT images would be helpful to make a decision on radiation-dose distribution for treatment because the patient images can be obtained in the similar condition under radiation therapy. In addition, anti-tumor effect of radiation therapy is now precisely controlled for target. Therefore, precise information of tumor, such as extent of tumor and heterogeneity within tumor, would make t...

Abstract Current status of deformable image registration (DIR) and auto-segmentation for various medical imaging types (e.g., CT, MR, and CBCT) is reported. First, we introduce the advantage/disadvantage of DIR between (1) CT and CT, (2) CT and CBCT, (3) MR and MR, and (4) CT and MR. Next, we explain an atlas-based segmentation. Our explanation about DIR and auto-segmentation will help for understanding DIR technique. PMID: 31168032 [PubMed - in process] (Source: Igaku Butsuri: Japanese Journal of Medical Physics)

[Use of Deformable Image Registration for Dose Accumulation].
Abstract Deformable image registration (DIR) can be used for accurate dose mapping between multiple radiotherapy image set. Dose accumulation based on DIR is playing an important role in advanced radiation therapy, such as 4 dimensional radiation therapy and adaptive Radiotherapy. The accuracy of dose mapping depends on the accuracy of the deformation vector fields arising from DIR and on the local dose gradient in the irradiated geometry. Therefore, in clinical use, patient-specific verification should be performed. In this article, challenges and points to notice on DIR based dose accumulation are overviewed and...

[Review of Deformable Image Registration for Clinical Application].
Abstract One of the characteristics of deformable image registration (DIR) is to detect anatomical coincidence points between two different images. The advantages of using DIR with radiotherapy are as follows. (1) to support the determination of the target using images of modality and series different from the treatment plan image, and (2) to evaluate the dose administered to the target and risk organs by summing the multiple dose distributions. Although DIR has been widely used in the field of external irradiation, application in the field of brachytherapy has been widespread in recent years. Also, the use of DIR...

[Outline of Deformable Image Registration for Clinical Use].
This article focuses the algorithm and fundamental matters of DIR by introducing intensity-based, contour-based algorithms, and hybrid algorithm. The intensity-based algorithm calculates the DVF by optimizing the index that measures the degree of coincidence of the intensity of two images. On the other hand, the contour-based algorithm calculates DVF by applying a physical model that moves the contour points on the moving image to the corresponding contour points of the target image. Recently, hybrid methods using both image intensity information and contour information can also be used. Factors influencing accuracy of DIR...
