A medical training apparatus comprising an instrument holder with a medical instrument, a model patient body simulating a patient subject to medical treatment or examination, and an examination table on which the model patient body is placed. The medical training apparatus comprises a posture detection means for detecting the posture of the examination table, a medical instrument status detection means for detecting the working status of the medical instrument, an examination receiving status detection means for detecting the situation of the model patient body in medical treatment or examination, and a model patient body driving means housed in the model patient body. The model patient body driving means changes the facial or body expression of the model patient body, depending on combination of at least one of the posture detection signal output from the posture detection means and the medical instrument status detection signal output from the medical instrument status detection means, and the examination receiving status detection signal output from the examination receiving status detection means.

Medical training apparatus

A medical X-ray CT imaging apparatus, a medical X-ray CT image display device, and a medical X-ray CT image display method which perform CT imaging of living organs symmetrically located with respect to a predetermined plane and display CT images thereof. This is a method of displaying a medical X-ray CT image, where a CT image obtained by X-ray CT imaging, using a cone beam (B), of a first living organ and a second living organ which are symmetrically located with respect to the predetermined plane. In the present invention, the CT image of the first living organ and that of the second living organ are displayed for comparison on one display screen of a display means.
