PROBLEM TO BE SOLVED: To provide an ultrasonic image display apparatus capable of quickly puncturing a puncture needle by exchanging positions of a short-axis image and a long-axis image on a screen according to a direction of an ultrasonic probe.SOLUTION: A blood flow imaging apparatus as an ultrasonic image display apparatus uses an ultrasonic probe to simultaneously displays a short-axis image 8 and a long-axis image 9 on a same screen 10 on the basis of a reflection wave signal obtained by transmitting/receiving ultrasonic waves. When inputting an exchange signal for instructing to exchange the left/right of the positions of the images, the ultrasonic image display apparatus performs image processing of exchanging the left/right of the positions of the short-axis image 8 and the long-axis image 9, displaying the short-axis image without reversing the left/right of the short-axis image 8, and displaying by reversing the left/right of the long-axis image 9.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】超音波プローブの向きに応じて画面上における短軸像及び長軸像の位置を入れ替え、穿刺針の穿刺を迅速に行うことができる超音波画像表示装置を提供すること。【解決手段】超音波画像表示装置としての血流撮影装置において、超音波プローブを用い、超音波を送受信して得た反射波信号に基づいて、短軸像８と長軸像９とを同一画面１０上に同時に表示する。画像の位置の左右入れ替えを指示する切替信号の入力時に、短軸像８及び長軸像９の位置を左右入れ替えるとともに、短軸像８の画像を左右反転させずに表示する一方で９長軸像の画像を左右反転させて表示する画像処理を行う。【選択図】図３
