Description

上記課題を解決するために本発明に係る治療支援装置は、医用画像撮像装置により被検体内部の病変部位を撮像して得られた被検体画像において、前記病変部位が撮像された病変領域を含む特定領域を設定する特定領域設定手段と、音響放射圧及び集束超音波を照射するプローブの位置を検出する位置検出手段と、前記音響放射圧による信号に基づいて前記集束超音波により前記被検体の組織変性が生じると推定される部位の位置情報を取得する情報取得手段と、前記プローブの位置と、前記組織変性が生じると推定される部位の位置情報と、に基づいて、前記被検体画像において前記組織変性が生じると推定される部位が撮像された治療予定領域を算出する治療予定領域算出手段と、前記治療予定領域が前記特定領域からはみだしている場合に警告を行う警告手段と、を備えたことを特徴とする。 In order to solve the above problems, a treatment support apparatus according to the present invention includes a lesion area in which a lesion site is imaged in a subject image obtained by imaging a lesion site inside a subject with a medical image imaging device. Specific area setting means for setting a specific area, position detection means for detecting the position of a probe that irradiates acoustic radiation pressure and focused ultrasound, and the focused ultrasound based on a signal from the acoustic radiation pressure information acquisition means for acquiring positional information of the portion is estimated to tissue degeneration occurs, the position of the probe, the position information of the area to be estimated and the tissue degeneration occurs, on the basis of, in the subject image A treatment planned region calculating means for calculating a treatment planned region in which a site estimated to cause the tissue degeneration is imaged, and a case where the treatment planned region protrudes from the specific region Characterized in that the warning means gives a warning, provided to.

また、本発明に係る治療支援システムは、被検体を撮像する医用画像撮像装置と、音響放射圧及び集束超音波を照射するプローブを備えた超音波診断治療装置と、前記医用画像撮像装置により被検体内部の病変部位を撮像して得られた被検体画像において、前記病変部位が撮像された病変領域を含む特定領域を設定する特定領域設定手段と、前記プローブの位置を検出する位置検出手段と、前記超音波診断治療装置が、前記プローブから照射される音響放射圧による信号に基づいて前記被検体の組織変性が生じると推定した部位の位置情報を取得する情報取得手段と、前記プローブの位置と前記組織変性が生じると推定した部位の位置情報と、に基づいて、前記被検体画像において前記組織変性が生じると推定された部位が撮像された治療予定領域を算出する治療予定領域算出手段と、前記治療予定領域が前記特定領域からはみだしている場合に警告を行う警告手段と、を備えたことを特徴とする。 In addition, a treatment support system according to the present invention includes a medical image imaging apparatus that images a subject, an ultrasonic diagnostic treatment apparatus that includes a probe that radiates acoustic radiation pressure and focused ultrasound, and the medical image imaging apparatus. In a subject image obtained by imaging a lesion site inside a specimen, a specific region setting unit that sets a specific region including a lesion region in which the lesion site is imaged, and a position detection unit that detects a position of the probe The ultrasonic diagnostic treatment apparatus acquires position information of a site that is estimated to cause tissue degeneration of the subject based on a signal by acoustic radiation pressure emitted from the probe, and the position of the probe wherein the position information of the sites was estimated to tissue degeneration occurs, based on the treatment pre said site is estimated that the tissue degeneration in a subject image caused is captured and A treatment plan area calculating means for calculating the area, the treatment plan area is characterized by comprising a warning means for performing a warning if protruding from the specific area.
