In a medical image diagnosis apparatus which forms a scanogram image of a subject and forms tomographic images under imaging conditions set by using the scanogram image, an imaging condition setting frameindependent of the scanogram imageis provided on a monitor. Desired imaging for which imaging conditions are to be set is designated by inputting a numeric value presenting an ordinal number for imaging in a numeric value input boxin the imaging condition setting frame. A pointer is set to a frame, a markor a dotted lineand dragged, thus enabling imaging conditions indicating the number of instances of imaging and image reconstruction and image reconstruction positions for the designated imaging. Settings in the imaging condition setting frameare reflected in a frameA and linesB on the scanogram imageindicating the number of instances of imaging and image reconstruction and image reconstruction positions. In this way, the frame, lines and so on displayed on the scanogram image and indicating the imaging conditions for the desired imaging can be operated speedily and correctly.

Medical image diagnosis apparatus

When CT imaging is effected by spiral scanning, an operator is required to set only one or two of three imaging conditions to be set, that is, a bed moving speed, a slice width of irradiation X-ray beams and an image reconstruction pitch. The CT apparatus according to the present invention determines in advance the relationship between these three imaging conditions so that when one or two of these imaging conditions are inputted, the remaining imaging condition or conditions are specified in the light of this relationship.
