CBL teaching was carried out in the experimental group, and LBL teaching was carried out in the control group. According to the standardized training course design, after one year of image post-processing course teaching, the teaching effect was evaluated through closed-book examination, questionnaire survey and post-processing test. SPSS 20.0 was used for t-test and Mann-Whitney U test. Results:The scores of closed-book examinations (74.42±6.10) and post-processing test (73.47±6.03) in the experimental group were higher than those in the control group [(69.11±3.70) and (69.08±6.51)], and the difference was statistically significant ( P<0.05). The questionnaire survey showed that the students in the experimental group recognized CBL teaching in terms of learning interests stimulation, classroom atmosphere mobilization, clinical thinking cultivation, self-study ability training, and analysis of difficult and rare cases, etc. Conclusion:In the image post-processing course of standardized training of medical imaging technology, the rational application of CBL teaching mode is helpful to improve students' learning enthusiasm, self-learning ability, comprehensive analysis of clinical ability, practical ability, innovation consciousness and so on.

Exploration on teaching and experiment reform of medical imaging technology course from the perspective of "Internet Plus-based teaching diagnosis and reform" / 中华医学教育探索杂志

Medical imaging technology course has the characteristics of strong professionalism, complicated content to understand, and quickly updated knowledge. In traditional teaching mode, it takes teachers a lot of time to prepare lessons, and the teaching tools are limited like only taking use of blackboard, model and wall maps, which not only makes teaching content boring but also hardly stimulates students' initiative. Teaching reform of medical imaging technology courses from the perspective of "Internet Plus-based teaching and diagnosis reform" involves teaching content, teaching concept, teaching mode, teaching evaluation and experiments, etc., in which computer-aided teaching, flipped classroom, micro-course and high-quality resource-sharing course are used to increase experimental content, reform experimental teaching methods, and create "real-situation" experimental environment as well as other teaching diagnosis and reform measures, aiming to explore a new teaching pattern that meets the development of students majoring in medical imaging technology and the demand for social talents.

Deep Learning-Based Cardiac Imaging Data Measurement and Its Application in Diagnosis of Sudden Cardiac Death / 法医学杂志

In the field of forensic medicine, diagnosis of sudden cardiac death is limited by subjective factors and manual measurement methods, so some parameters may have estimation deviation or measurement deviation. As postmortem CT imaging plays a more and more important role in the appraisal of cause of death and cardiopathology research, the application of deep learning such as artificial intelligence technology to analyze vast amounts of cardiac imaging data has provided a possibility for forensic identification and scientific research workers to conduct precise diagnosis and quantitative analysis of cardiac diseases. This article summarizes the main researches on deep learning in the field of cardiac imaging in recent years, and proposes a feasible development direction for the application of deep learning in the virtual anatomy of sudden cardiac death at present.

Characteristics and enlightenment of teaching and clinical model of medical imaging in Italy / 中华医学教育探索杂志

Italian medical imaging education includes two parts: training for radiologists and for radiologic technologists. To be a radiologist, the six-year medical students after graduation must complete specialty training in radiology and pass the examination. Radiologic technologists are selected from the three-year bachelor graduates of medical imaging technology. There are basic medical science courses, cultural practice and clinical practice in medical college every year. Continuing medical imag-ing education includes lectures, case discussions and other forms. Radiologists are required to master all kinds of imaging techniques, working as clinical rotation in every section of medical imaging depart-ment. Patients need to make an appointment before having the medical imaging examination. Through the analysis of the characteristics of Italian medical imaging teaching and clinical patterns, the author puts forward the suggestion of putting emphasis on medical imaging curriculum reform, the full imple-mentation of the early clinical contact, and at the same time improving the professional medical image training mode to improve the radiologists' clinical ability.

O aparelho é como um automóvel; a pista é a paciente: para além do ensino de tecnologia no pré-natal / The apparatus is like a car; the road is the patient: beyond the teaching of technology in prenatal care

O presente estudo contempla as práticas e ideias envolvidas na formação acadêmica de um grupo social relevante: o dos médicos que, dada sua posição hierárquica significativa na produção da marca ultrassom obstétrico, parece-nos ser um ponto de "parada" interessante e fundamental no fluxo circular entre ideias, marcas e coisas que constituem esse objeto, ultrassom. A observação etnográfica da situação de ensino permite captar dinamicamente esse momento fundamental no qual os principiantes são apresentados a uma tecnologia que foi histórica (e provisoriamente) constituída como indispensável no acompanhamento pré-natal. Pretende-se, assim, apreender de que modo é produzida a "socialização visual" dos futuros profissionais; a pesquisa empírica evidenciou que, juntamente com um determinado tipo de olhar, outros elementos bastante heterogêneos também são ensinados aos futuros médicos. Uma tensão bastante presente no campo consiste na dicotomia entre uma abordagem eminentemente clínica e outra, de teor fortemente tecnicista. A eventual precariedade de dispositivos tecnológicos evidencia diversos paradoxos e incongruências nesta segunda tendência. As modificações ocorridas no desenrolar dos diversos processos que se articulam no campo observado são discutidas em termos do que são capazes de revelar sobre os grupos sociais envolvidos em sua produção.

This study analyzes the practices and ideas involved in the academic formation of an important social group: the doctors who, given their significant hierarchical position in the production of the obstetric ultrasound mark seem, in our opinion to be an interesting and fundamental "stopping" place in the circular flow of ideas, marks and things that form the ultrasound object. The ethnographic observation of the teaching situation allows the dynamic capture of this fundamental moment when beginners are introduced to a technology that was historically (and provisionally) considered indispensable in prenatal monitoring. The intention is thus to apprehend how the "visual socialization" of future professionals is produced; the empirical research showed that, together with a certain kind of gaze, other quite heterogeneous elements are also taught to the future doctors. A tension that is significantly present in the field is the dichotomy between an eminently clinical approach and another one that is strongly technicist. The contingent precariousness of technological devices evidences various paradoxes and incongruences in the latter. The changes during the development of the various processes that are articulated in the observed field are discussed in terms that provide insights into the works of the social groups that produced them.

'É... tá grávida mesmo! E ele é lindo!' A construção de 'verdades' na ultra-sonografia obstétrica / 'Yeah, you're pregnant all right! And he's beautiful!' The construction of 'truths' in obstetric ultrasonography

O ultra-som obstétrico sofreu uma transformação peculiar no Brasil, sendo uma tecnologia de imagem médica que progressivamente transformou-se em uma modalidade de 'consumo' e 'lazer'. Analisa-se a produção de 'verdades' construídas durante exames de ultra-som, calcadas nas crenças médicas e não-médicas acerca da 'objetividade' da imagem técnica. Baseia-se em material etnográfico obtido em clínicas de imagem do Rio de Janeiro. Os exames de ultra-som sublinham a questão da subjetividade/objetividade presente em todas as tecnologias de imageamento médico, por ser uma tecnologia dinâmica e interativa. Durante os exames os atores são agentes ativos, produzindo e reproduzindo 'verdades' médicas e não-médicas sobre a gravidez e o feto. Essas 'verdades' desempenham papel relevante no processo em que, simultaneamente, é reconfigurada a gravidez, o feto é subjetivado e uma prática médica se transforma em espetáculo. Essa produção funciona como um mecanismo de realimentação, reassegurando os atores acerca da saúde da gestante e do feto e, ao mesmo tempo, reafirmando o lugar da tecnologia de imagem médica como produtora privilegiada de verdades sobre os corpos.

Obstetrical ultrasound is a technology which has undergone a peculiar transformation. In Brazil what began as a medical imaging technology is progressively being transformed into a modality of consumption and 'leisure'. In this paper I discuss the production of 'truths' - founded on medical and non-medical beliefs about the 'objectivity' of medical imaging technologies -, during obstetrical ultrasound exams. The discussion is based on ethnographic material obtained in private imaging clinics in Rio de Janeiro, Brazil. Ultrasound exams underscore the subjectivity/objectivity issue belonging to all medical imaging technologies, due to the peculiarity of being a dynamic and interactive practice. During an obstetrical ultrasound the actors are active agents in producing or reproducing medical and non-medical 'truths' about the pregnancy and the fetus. Those 'truths' play a central role simultaneously reconfiguring the pregnancy, subjectivizing the fetus, and transforming a medical practice into a spectacle. This production acts as a feedback mechanism, reassuring the actors about the healthy state of the pregnant woman and the fetus as well as reaffirming the position of medical imaging technologies as privileged producers of truths about the human body.
