【摘要】：目的研究相同超聲紋理在不同超聲儀上獲取的游程長度紋理測量值是否存在顯著差異。方法 30例正常志愿者,男女各半,分別在兩臺(tái)不同超聲儀的相同設(shè)置和不同設(shè)置條件下取右小腿外側(cè)腓腸肌縱切面圖像。用自行研制的軟件,以32×32像素點(diǎn)的正方形取樣框?qū)λD像中最典型的腓腸肌紋理進(jìn)行取樣,計(jì)算其游程長度紋理參數(shù),用配對(duì)t檢驗(yàn)檢測相同設(shè)置和不同設(shè)置下兩臺(tái)超聲儀上所取圖像的紋理測值是否差異顯著。結(jié)果配對(duì)t檢驗(yàn)結(jié)果顯示不同儀器相同設(shè)置和不同設(shè)置條件下配對(duì)的12個(gè)紋理參數(shù)中有9個(gè)存在顯著性差異(P0.05)。結(jié)論不論在相同設(shè)置還是不同設(shè)置下,相同對(duì)象相同部位的腓腸肌超聲紋理用不同的超聲儀取圖測量,游程長度測量的紋理測值大部有顯著的差異,這也就是說在各種超聲儀器上采集的圖像用游程長度分析進(jìn)行超聲紋理的測量,所測值不能進(jìn)行相互比較。
[Abstract]:Objective to study whether there are significant differences in the length texture measurement values of the same ultrasonic texture obtained on different supersonic instruments. Methods 30 normal volunteers, half male and half male, received longitudinal section images of the lateral gastrocnemius muscle of the right leg under the same setting and different setting conditions of two different supersonic instruments. The most typical gastrocnemius texture in the image was sampled with the square sampling box of 32 脳 32 pixels, and the run-length texture parameters were calculated. A paired t test is used to detect whether the texture values of the two supersonic images in the same and different settings are significantly different. Results the paired t test results showed that there were significant differences in 9 out of 12 texture parameters in the same settings and different settings of different instruments (P0.05). Conclusion whether in the same setting or different settings, the ultrasonic texture of the same object and the same part of gastrocnemius were measured by different ultrasound instruments, and most of the texture values measured by the length of run were significantly different. This means that the images collected on various ultrasonic instruments can not be compared with each other.
