Ultrasound diagnosis apparatus is provided which easily recreates test conditions same as the past, comprising scanner, signal processor, display controller, storage, detector, collator, and controller. Scanner scans a subject with ultrasound waves through ultrasound probe. Storage previously stores first relevant information in which operation of the scanner, the signal processor, or the display controller in past test is related to a first relative position which is the relative position of ultrasound probe for the subject in the same past test. Detector detects a second relative position which is the present relative position of ultrasound probe for the subject. Collator collates the first relative position and the second relative position detected by the detector. Controller controls the scanner, the signal processor or the display controller based on the operation related to the first relative position, when the first relative position and the second relative position are matched in collation.
