The Thyroid Navigator is the 3D graphics model of around the thyroid. It developed to be utilized on the various medical scenes as the communication tool in any kind of disease of the thyroid. It displays clearly the perspective from the skin, the benign tumor, the thyroid cancer, the lymph node metastasis, tracheal invasion, the chronic thyroiditis, relationship of thyroid and trachea, recurrent laryngeal nerve, artery, and vein, a postop condition, a parathyroid-tumor. Please use for description to the patient, education scene, in a variety of medical scene. - The three dimensional model which specialized at the thyroid. - It displays 360 degrees rotated. - It displays a thyroid in 3 patterns, states of the skin, vessels and nerves, only nerve. - It displays some symptoms of tumor sample. - It introduces the image of the preoperative, the postop on each case basis. - It is ideal for teaching physicians, nurses, laboratory technicians to that aims to thyroidology. - Compatible language is English and Japanese. <詳細> サイロイド・ナビゲーターは、甲状腺とその周辺組織を詳細に再現した3Dグラフィックスモデルです。拡大、縮小、回転により容易に細部まで観察することができます。 甲状腺疾患の診療におけるコミュニケーションツールとして、患者様への説明や甲状腺を学ぶ医療従事者への教育など、さまざまな医療現場でご活用いただくことを目的として開発しました。 皮膚からの透視図、甲状腺の良性腫瘍、甲状腺癌、リンパ節転移、気管浸潤、慢性甲状腺炎、甲状腺と気管、反回神経、動静脈との関係、術後の状態、副甲状腺腫瘍などをわかりやすく表示し、さらに理解を深めることができます。 - - - - - - - - - - - - - - - - - - - - - - - - - - - - -   * 甲状腺に特化した3Dグラフィックスモデル  * 360度回転させて表示  * 甲状腺を“皮膚のある状態”、“血管と神経”、“神経のみ”の3パターンで表示  * 腫瘍の症状サンプルを数パターン表示  * 症例ごとに術前、術後のイメージを表示 - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Read full description

The app was developed and well-validated from real normal and hypothyroid human data and it features a simple and intuitive user interface, designed to promote understanding of the basic physiology of this complex endocrine system – by laypersons as well as by clinicians and clinical educators and researchers. THYROSIM is particularly useful for understanding and safely exploring effects of perturbing the real system, in various ways – without the need for any real human or animal experimentation. The DIRECTIONS and EXAMPLE explain and illustrate normal physiological conditions. Users can then conduct simulated ‘‘what-if’’ experiments, to challenge the simulation model with abnormal conditions – as explained on the app interface pages. For example, users can simulate hypothyroidism (when the thyroid hormone level in blood is too low) or thyroid hormone malabsorption from the gut. Patients with hypothyroidism can visualize the effects of thyroid hormone replacement therapy, promoting adherence to their doctor’s dosing prescriptions, and also understand better why they should take thyroid hormone replacement drugs without food – facilitating understanding of impaired absorption of the drug in the presence of food. Thyroid cancer patients (any layperson) can visualize the effects of partial or complete surgical removal of the thyroid gland (thyroidectomy) on blood hormone levels, and thereby understand why they need individualized hormone replacement therapy, and so on. Physicians and laypersons can use THYROSIM as a patient education tool. Scientists can use THYROSIM for clinical research purposes. Clinical and pharmacology educators can use THYROSIM to teach medical and pharmacology students basic thyroid hormone physiology and pathophysiology, complete with easy to understand graphical renditions of the results of “what-if” experimentation with the simulator. Trainees and other students can benefit from use of THYROSIM as a means to deepen and test their understanding the complexities of the “pituitary-thyroid axis”, the primary organ interactions regulating blood thyroid hormone levels by feedback control. The THYROSIM model has been the basis for several important clinical study applications for well over a decade, with details published in the medical journals Thyroid and Frontiers in Endocrinology.
