Utilizing echoic intension and distribution from different organs and local details of human body, ultrasonic image can catch important medical pathological changes, which unfortunately may be affected by ultrasonic speckle noise. A feature preserving ultrasonic image denoising and edge enhancement scheme is put forth, which includes two terms: anisotropic diffusion and edge enhancement, contro...

When multiple microphones are used to reproduce multiple sources microphone interference, or bleed, can occur due to each microphone picking up more than one source. This paper proposes combining the crosstalk resistant adaptive noise canceller (CTRANC) algorithm with centred adaptive filters using an estimation of delay to suppress the interference, while making little change to the target sig...

A 47-year-old woman presented with shortness of breath and edema of lower limbs for 3 months. Echocardiography showed an iso-echoic lesion in the right atrium and IVC (Fig. 1a), while CT revealed an intensely enhanced mass in the region above (Fig. 1b and c). Debulking was successfully completed and histo-pathologic diagnosis is consistent with angiofibroma (Fig. 1d). Figure 1: (a) Transthoraci...

A 3.5-year-old Boxer breed bitch was referred to our clinic with a history of progressive and painless inguinal mass on the left side with no significant general symptoms. Ultrasonographic examination of the inguinal mass and abdomen revealed a hypo echoic area covered with a hyper echoic capsule in inguinal mass and also two 40-day-old live foetuses, respectively. During ventral midline laparo...
