In the vicinity of the subject P placed on the bed in the supine position, the transmitter 31 of the position detection unit 30 is arranged in a predetermined direction with respect to the subject P. Then, after an operation for starting collection of image data is performed after the information on the body shape of the subject P and the 3D placement operation are performed from the operation unit 80, the ultrasound diagnostic apparatus 100 starts operation (step S1).

  The system control unit 90 instructs the imaging unit 50 and the image processing unit 60 to perform inspection. The B-mode data generation unit 41 of the data processing unit 40 in the imaging unit 50 starts from the reception unit 22 of the transmission / reception unit 20 with the tip of the ultrasonic probe 10 in contact with the vicinity of the first part of the examination part of the subject P. The output reception signal is processed to generate B mode data. Then, the generated B-mode data is output to the image data generation unit 43.

Still B-mode image data 70 is displayed in the first display area 65 of the screen 64a. In addition, the 3D model 71 is displayed in the second display area 66.

  Here, in order to determine the relative reference position of the ultrasonic probe 10 with respect to the 3D model 71 when the ultrasonic scanning is performed to generate the B-mode image data 70, the position of the ultrasonic probe 10 from the operation unit 80 is determined. When the operation for designating is performed, the placement unit 62 places a probe mark indicating the position of the ultrasonic probe 10 on the 3D model 71. Then, the 3D model 71 and the probe mark arranged on the 3D model 71 are output to the display unit 63. The display unit 63 displays the 3D model 71 and probe marks output from the arrangement unit 62 together with the B-mode image data 70 (step S3 in FIG. 4).

The B-mode image data thus displayed is displayed in real time. When a still operation is performed after the first storage operation is performed from the operation unit 80, the image data generation unit 43 displays the stationary B-mode image data on the display unit 63.

  When an n-th storage operation (n is an integer of 2 or more) for storing still B-mode image data is performed from the operation unit 80, the image data generation unit 43 converts the stored B-mode image data into stored image data that is still B-mode image data. The reduced image data of this image data is added. Further, the n-th position and angle data corresponding to the stored image data supplied from the system control unit 90 and the inspection information are added to the stored image data. Then, the image data storage unit 61 stores the saved image data to which the additional information composed of the reduced image data, the nth position and angle data, and the inspection information is added. Then, when collection of image data useful for diagnosis is completed and an operation for stopping collection is performed from the operation unit 8, the imaging unit 50 stops its operation.

  When an examination list display operation is performed from the operation unit 80 after the collection stop operation, the arrangement unit 62 reads the examination time and subject information included in the incidental information stored in the image data storage unit 61 to obtain an examination list. Data is created, and the created examination list data is displayed on the display unit 63.

  Next, when an examination selection operation for selecting an examination of the subject P from the examination list data is performed from the operation unit 80, the arrangement unit 62 displays the reduced image data, the position, and the reduced image data included in each supplementary information of the selected examination. The angle data, body shape information, 3D model 71, and mark position information are read from the image data storage unit 61. Then, 3D layout image data is generated based on the read information, and the generated 3D layout image data is displayed on the display unit 63 (step S5 in FIG. 4).

  Here, 3D reduced image data is generated by tilting the reduced image data generated by the first saving operation to an angle corresponding to the first angle data, and the generated 3D reduced image data is arranged at the mark position. Further, 3D reduced image data is generated by tilting the reduced image data generated by the n-th saving operation to an angle corresponding to the n-th angle data, and the generated 3D reduced image data is converted to the n-th time of the 3D model 71.
