The cryotherapy control system uses a cryotherapy unit 40 in which a cryotherapy probe (402 in FIG. 2) is brought into contact with the affected area of the patient 24 to freeze and treat the affected area, and a plurality of ultrasonic probes 54 and 55. An ultrasound image acquisition unit 51 that transmits and receives ultrasound to and from the patient 24 and acquires an ultrasound image using the received reflected echo signal, the cryotherapy probe (402), and the ultrasound probes 54 and 55 The three-dimensional position detection unit 9 for detecting the position and the plurality of ultrasonic images acquired by the ultrasonic image acquisition unit 51 at the positions of the plurality of ultrasonic probes 54, 55 An image processing unit 19 that synthesizes images and an image display unit 13 that displays an image of the cryotherapy region are provided.

術者29は、術具27を患者24の患部まで誘導するにあたって、超音波画像取得部51で撮像した画像を併せて確認している。超音波探触子54、55は超音波画像取得部51に接続されており、超音波探触子54、55によって複数の超音波画像を取得でき、これら取得された超音波画像を表示できるようになっている。
When guiding the surgical instrument 27 to the affected area of the patient 24, the surgeon 29 also confirms the image captured by the ultrasonic image acquisition unit 51. The ultrasonic probes 54 and 55 are connected to the ultrasonic image acquisition unit 51 so that a plurality of ultrasonic images can be acquired by the ultrasonic probes 54 and 55, and the acquired ultrasonic images can be displayed. It has become.

一方、術具27は冷凍治療部40と接続されており、例えば冷凍治療用プローブの温度など凍結治療情報がモニタ38に表示される。
On the other hand, the surgical instrument 27 is connected to the cryotherapy unit 40, and cryotherapy information such as the temperature of the cryotherapy probe is displayed on the monitor 38, for example.

<実施例1のアイスボールの検出の原理>
まず、超音波画像取得部51を用いたアイスボールの検出の原理について図4を用いて説明する
図4は、実施例1の超音波画像取得部51を用いたアイスボールの検出の原理を説明する図である。アイスボール501へは、患者24の体外から超音波探触子54、55によって連続して超音波503、505が送信される。このとき、超音波は密度の高い氷を透過せず反射するが、凍結領域512、522の境界面の画像、すなわちアイスボールとの境界面の画像511、521がそれぞれ得られる。
<Principle of Ice Ball Detection in Example 1>
First, the principle of ice ball detection using the ultrasonic image acquisition unit 51 will be described with reference to FIG. 4. FIG. 4 illustrates the principle of ice ball detection using the ultrasonic image acquisition unit 51 of Example 1. It is a figure to do. Ultrasonic waves 503 and 505 are continuously transmitted to the ice ball 501 from the outside of the patient 24 by the ultrasonic probes 54 and 55. At this time, the ultrasonic waves are reflected without passing through high-density ice, but images of the boundary surfaces of the frozen regions 512 and 522, that is, images 511 and 521 of the boundary surfaces with the ice balls are obtained, respectively.

超音波画像取得部51は、3次元位置検出のためのポインタが取り付けられた複数の超音波探触子54、55を用いてアイスボール像511、521を取得し、超音波画像取得部51のモニタ52に表示する(ステップS601)。
The ultrasonic image acquisition unit 51 acquires ice ball images 511 and 521 using a plurality of ultrasonic probes 54 and 55 to which pointers for three-dimensional position detection are attached, and the ultrasonic image acquisition unit 51 The information is displayed on the monitor 52 (step S601).

実施例1によれば、冷凍治療用プローブ402を患者の患部に接触させ当該患部を凍結して治療する冷凍治療部40と、超音波探触子54,55を用いて前記患者に超音波を送受信し、受信した反射エコー信号を用いて超音波画像を取得する超音波画像取得部51と、前記冷凍治療用プローブと前記超音波探触子の位置を検出する三次元位置検出部9と、前記超音波探触子54、55の複数の位置において前記超音波画像取得部51によって取得された複数の超音波画像を用いて前記冷凍治療領域の画像を合成する画像処理部19と、前記冷凍治療領域の画像を表示する画像表示部13と、を備えているので、冷凍治療を行う場所がMRI装置を設置したシールドルーム等に限られないから、冷凍治療制御システムは治療場所の制約を受けないという効果がある。
According to the first embodiment, the refrigeration therapy probe 402 and the freezing treatment portion 40 to treat by freezing the affected part is brought into contact with the affected area of the patient, the ultrasonic waves to the patient using the ultrasound probe 54, 55 An ultrasonic image acquisition unit 51 that transmits and receives and acquires an ultrasonic image using the received reflected echo signal, a three-dimensional position detection unit 9 that detects the positions of the cryotherapy probe and the ultrasonic probe, An image processing unit 19 that synthesizes images of the cryotherapy region using a plurality of ultrasonic images acquired by the ultrasonic image acquisition unit 51 at a plurality of positions of the ultrasonic probes 54 and 55; And an image display unit 13 for displaying an image of the treatment area, and the place where the cryotherapy is performed is not limited to the shield room or the like where the MRI apparatus is installed. There is no effect.

超音波画像取得部51は、3次元位置検出のためのポインタが取り付けられた複数の超音波探触子54、55、56を用いてアイスボールの超音波画像511、521、541を取得し、モニタ52に表示する(ステップS801)。
The ultrasonic image acquisition unit 51 acquires the ultrasonic images 511, 521, and 541 of an ice ball using a plurality of ultrasonic probes 54, 55, and 56 to which pointers for three-dimensional position detection are attached, The information is displayed on the monitor 52 (step S801).
