Quantitative Schlieren Image-Noise Reduction Using Inverse Process and Multi-Path Integration

Journal of Flow Control, Measurement & Visualization 2020年第2期8卷 25-44页

This report deals with introducing two new techniques based on a novel concept of complex brightness gradient in quantitative schlieren images, “inverse process” and “multi-path integration” for image-noise reduction. Noise in schlieren images affects the projections (density thickness) images of computerized tomography (CT). One spot noise in the schlieren image appears in a line shape in the density thickness image. Noise effect like an infectious disease spreads from a noisy pixel to the next pixel in the direction of single-path integration. On the one hand, the noise in the schlieren image reduces the quality of the image and quantitative analysis and is undesirable;on the other it is unavoidable. Therefore, the importance of proper noise reduction techniques seems essential and tangible. In the present report, a novel technique “multi-path integration” is proposed for noise reduction in projections images of CT. Multi-path integration is required the schlieren brightness gradient in two orthogonal directions. The 20-directional quantitative schlieren optical system presents only images of schlieren brightness in the horizontal gradient and another 20-directional optical system seems necessary to obtain vertical schlieren brightness gradient, simultaneously. Using the “inverse process”, a new technique enables us to obtain vertical schlieren brightness gradient from horizontal experimental data without the necessity of a new optical system and can be used for obtaining any optional directions of schlieren brightness gradient.

在日本中部关东地震进行地震学的泊松比测绘发现蛇纹石化橄榄石，因为在地壳和上地幔，蛇纹岩比其它岩石具有较高的泊松比。我们应用走时层析成像技术确定三维P波、S波速度模型，然后作出泊松比的三维图，这些模型显示出在20－70km深度范围内的板块上边界存在低速异常。在低速区20－45km深度上有一个泊松比大于0．3的区域，我们将其归因于蛇纹石化橄榄石，低速区的其他部分被解释为具有泊松比0．25的下斜大洋地壳。高泊松比区域的地震活动性较低并且板块间的耦合也比较弱，蛇纹岩的延展性与此相符。

Breast Conserving Surgery and Sentinel Lymph Node Biopsy under Local Anesthesia for Breast Cancer

引用

Journal of Cancer Therapy 2012年第5期3卷 810-813页

作者： shinichiro Kashiwagi Naoyoshi Onoda Tsutomu Takashima Yuka Asano Naoki Aomatsu Masanori Nakamura Hidemi Kawajiri Tetsuro Ishikawa Kosei Hirakawa Department of Surgical Oncology Osaka City University Graduate School of Medicine Osaka Japan

Background: Breast conserving surgery and sentinel lymph node biopsy has become the standard operation for early breast cancer. This operation has been performed under local anesthesia for patients that would like short-term admission or for those not indicated for general anesthesia due to complications. This report presents the outcomes of breast conserving surgery and sentinel lymph node biopsy under local anesthesia. Patients and Methods: The study included 61 patients with breast cancer that were all definitely diagnosed before surgery. The indications were preoperatively diagnosed localized DCIS, invasive carcinoma measuring less than 3 cm in tumor diameter on ultrasound, and tumors with negative axillary lymph nodes. The surgical procedures included breast conserving surgery associated with sentinel lymph node navigation biopsy. Results: The surgery could be performed under local anesthesia in all 61 patients, and no patient was converted to general anesthesia. Four patients had sentinel lymph node metastasis. Surgical stumps were positive in 18 patients (29.5%). Ten Gy of boost irradiation of the tumor bed was added to the conventional breast irradiation for these patients. There were no serious complications associated with surgery. Conclusion: Breast conserving surgery and sentinel lymph node biopsy for early breast cancer can be performed safely under local anesthesia. This procedure contributes to shortening the length of hospitalization and thereby saving medical resources without deceasing the quality of treatment.

Pancreatectomy and splenectomy for a splenic aneurysm associated with segmental arterial mediolysis

World Journal of Gastrointestinal Surgery 2015年第5期7卷 78-81页

Segmental arterial mediolysis(SAM) is characterized by intra-abdominal, retroperitoneal bleeding or bowel ischemia, and the etiology is unknown. A 44-year-old man complaining of abdominal pain was admitted to our hospital. He had been admitted for a left renal infarction three days earlier and had a past medical history of cerebral aneurysm with spontaneous remission. The ruptured site of the splenic arterial aneurysm was clear via a celiac angiography, and we treated it using trans-arterial embolization. Unfortunately, the aneurysm reruptured after two weeks, and we successfully treated it with distal pancreatomy and splenectomy. We recommended a close follow-up and prompt radiological or surgical intervention because SAM can enlarge rapidly and rupture.

Antibody markers in the diagnosis of inflammatory boweldisease

World Journal of Gastroenterology 2016年第3期22卷 1304-1310页

Inflammatory bowel disease(IBD), including Crohn's disease and ulcerative colitis, is a chronic intestinal inflammation of unknown etiology. The diagnosis of IBD is based on endoscopic, radiologic and histopathologic criteria. Recently, the search for a noninvasive marker that could augment or replace part of this diagnostic process has become a focus of IBD research. In this review, antibody markers, including microbial antibodies, autoantibodies and peptide antibodies, will be described, focusing on their common features. At present, no single marker with qualities that are satisfactory for the diagnosis and treatment of IBD has been identified, although panels of some antibodies are being evaluated with keen interest. The discovery of novel IBD-specific and sensitive markers is anticipated. Such markers could minimize the use of endoscopic and radiologic examinations and could enable clinicians to implement individualized treatment plans designed to improve the long-term prognosis of patients with IBD.

Prognostic Value of SUVmax of <sup>18</sup>F-FDG PET/CT in Early Stage Breast Cancer with No LN Metastasis

引用

Open Journal of Medical Imaging 2017年第3期7卷 112-123页

作者： Ryusuke Murakami Yoshimitsu Fukushima Hitomi Tani Kotomi Iwata shinichiro Kumita Maki Nakai Tomoko Kurita Keiko Yanagihara Hiroyuki Takei Miyuki Matsubara Department of Radiology Nippon Medical School Hospital Tokyo Japan Department of Breast Surgery Nippon Medical School Hospital Tokyo Japan Division of Diagnostic Pathology Nippon Medical School Hospital Tokyo Japan

Purpose: To investigate the correlation between SUVmax of FDG-PET/CT and pathological findings including prognostic factors in early-stage T1-T2 breast cancer patients with no LN metastasis. Materials and Methods: This retrospective study investigated 75 patients (mean age 58.9 years;age range 30 - 82 years) with invasive breast cancer who underwent FDG-PET/CT for preoperative staging. All patients underwent subsequent surgery without prior neoadjuvant chemotherapy or endocrine therapy, and those who were confirmed to have T1- or T2-stage by histopathology with no LN metastasis were included. Two patients who had no perceptible FDG accumulation on PET/CT scans were excluded. The correlations between the SUVmax of the tumor and the pathological and immunohistochemical data were evaluated. Results: The mean SUVmax for the total 73 tumors was 5.46 ± 4.05. The mean SUVmax was 3.95 ± 3.28 for the T1 stage group (n = 36) and 7.23 ± 4.10 (p p p p = 0.008), and high Ki-67 status (p < 0.001), respectively. Conclusion: In T1-T2 breast cancer with no LN metastasis, the SUVmax of FDG-PET/CT had significant positive relationships with several prognostic parameters of pathological status. Even in early-stage breast cancer patients, pretreatment FDG-PET/CT is useful for predicting malignant behavior and prognosis).

河流健康指标是评价河流健康状况和河流生态系统完整性的标尺,是准确、全面评价河流生态系统健康状况的基础。国内现有河流健康指标大多针对河流生态系统的结构性,而对河流的功能性关注不多。本文系统综述了国外河流功能性指标的研究进展与应用现状,并对两种的典型功能性指标的应用方法和评价标准进行介绍。以日本大山川减水河段环境流量修复为案例,使用典型功能性指标和结构性指标对环境流量修复效果进行评价,结果表明河流功能性指标能更好地反映河流生态系统对流量变动的响应。本文研究成果可为完善我国河流健康评估体系提供借鉴。
