The knowledge and experience of specialists is now within your reach.

Diagnostic imaging, that development of technology enabled to bring useful information,
is essential for today’s medicine. However, there is a shortage of the specialists to diagnose
as highly specialized knowledge and skill are neccesary for diagnosis.
Medical Shinansha resolves this problem
by knowledge processing of specialists on medical information.

function1Diagnostic imaging navigation

Doc.navi guides users to select very likely diagnosis step by step from “procedure”, “region”, and “basic finding”.

(1)Procedure > (2)Region > (3)Baseic finding > (4)Dianosis

function2Imaging cases search

Selected and useful case images have information of “patient attribute”, “definitive diagnosis”, “medical record” and “specialist’s explanation.” From “basic finding”, “diagnosis”, etc. imaging cases to compare your patient’s one with are searched immediately, which helps you to diagnose efficiently.

Case explanation

Each case imaging contains specific explanations commented by specialists
how they figured it out.

Eirou Sakai, M.D.

Unsatisfied quality of medical imaging and wrong interpretation of the medical imaging are quite harmful for the patients. The quality of diagnosis of interns and residents and supportive reading by radiological technologists depend on the individuals. I do expect that Doc.navi will support users to improve their comprehensive capacity to read and interprete the medical imaging.

Tester’s VOICE doctors, interns and residents in hospitals or clinics, etc.

  • This is a real professional tool for accurate diagnosis and supports making prompt decisions for the patients.
  • When interpretation of medical imagings is fairly difficult, sample cases displayed guide us to make right diagnosis.
  • Easy and supportive to explain diagnostic results to patients by showing patient' images.
  • Easy and quick to prepare the medical records.
  • Easy to understand the concept and procedure of diagnostic imaging.
  • Supportive to restudy and recollect about the clinical findings learned while interns and residents as post graduate trainings.

The effective tool to improve the skill of each learner

point 1
Possible to select the contents for your skill
You can select the contents from “Region”, “Finding” and “Diagnosis.” Set your learning preferences to match the skill you need.
point 2
4 levels questions
About 1000 well-selected educational cases are presented as questions. They are divided into 4 levels, introduction, beginner, intermediate and advanced. You can set up questions according to your level.
point 3
Gradual improvement
If you use the function “Hint” well, your level can up gradually. Get the most out of “Hint” when you just start learning. Improving your skill, you’ll reduce the use of “Hint” and step up your level gradually.

Users’ voice

The almost actual-size images

It is good for me to observe clear case images well on the monitor. In addition, we can see not only the images with lesions but also the normal cases. This helped me a lot.

Simulation of reading images

I simulated the know-how of interpretations such as where and how the lesions were and what they were suspected to be finally. This was good chance for me to think about images neccesary for radiological technologists.

Preparation before getting a position

Knowing images necessary for diagnosis lets us get conscious of reading images useful for diagnosis and treatment. I want to acquire the skill and knowledge at clinical scenes.

Grab the skill to suspect any abnormality in the medical imaging at sight!

The role of medical imaging are getting more and more important in today’s medical science. Development of the modern medical imaging technologies has been providing rather detailed and accurate images that are essential as one of the most important diagnostic tools. Medical images are not just simple data but are valuable information of patients. Interpretation is the work to change mere data of the images into valued information of the patients. Acquiring the skill to interpret the information from the medical imaging is not only the power to understand the patients but also contribute to medical science. Due to cost efficiency, chest radiographs are the most applicable examinations for diagnosing the lung diseases in the most clinics and hospitals. Chest radiographs contain a variety of symptoms, and often provide the suspected diseases. I recommend the people studying medicine to become specialists to interpret the medical imaging by systematic learning methods. Simu.Doc contains many different types of cases that train you to find abnormalities in the medical images at sight. I am proud to introduce our “simu.Doc” to help you as the most powerful tool to get the skills.

What is Tutorial Database building  Diagnostic Imaging Tutor? Information comig in from the diagnosis flow process is provided by linking Knowledge Base with Imaging Case Database.

Knowledge Base

On the basis of huge case data, the knowledge base is constructed by extracting and grouping elements such as “region”,”basic findings”, and “diagnosis” necessary for diagnostic imaging and relating the respective elements. Thus, the evolution from data to knowledge has been realized by the Semantic Web technology that makes information have meanings.

Imaging Case Database

The imaging case database is constructed by extracting highly useful cases and adding information, such as patient's gender, age, definitive diagnosis and the reports given through correlation with the knowledge base, to the anonymized images of the cases. This has made it possible to use for a wide range of applications.
