If the number of clicks is 2, the blood vessel object is selected. If the number of clicks is 3, the bone B object is selected. In this case, objects in the depth direction may be sequentially selected according to the number of clicks, such as the bone A object is selected.
  • the click pressure of the pointing device is used, the click pressure is detected by installing a pressure sensor inside the pointing device. For example, as shown in Figure 21, if the click pressure is 2kPa, the bone A object should be selected, and if it is 3kPa, the blood vessel object should be selected! /.

Abstract

L'invention concerne un dispositif d'affichage d'images médicales permettant de synthétiser de manière efficace une pluralité d'images tridimensionnelles afin de réduire le travail de l'opérateur et de permettre de écourter le temps nécessaire pour un diagnostic d'image au moyen de l'image synthétisée. Les objets ou les images synthétisées sont affichés au niveau de deux régions d'affichage ou plus. Le dispositif d'affichage d'images médicales sélectionne un objet affiché au niveau de chaque région d'affichage par un dispositif de pointage et déplace l'objet sélectionné vers les autres régions d'affichage. L'objet déplacé est synthétisé avecun objet affiché au niveau de l'autre région et l'objet synthétisé est affiché au niveau de sa région correspondante. De plus, dans le cas où une pluralité d'objets sont affichés au niveau d'une région d'affichage, une pluralité d'objets sont synthétisés et les objets synthétisés sont affichés au niveau de la région d'affichage.
