Background Breast cancer can present as non-mass lesions (NMLs) on ultrasound. However, knowledge of and understanding about NMLs are scarce. Purpose To retrospectively investigate the final outcomes sonographic breast determine clinical radiologic variables associated with malignancy Material Methods In our database ultrasound examinations between 2011 2014, we found 119 women 121 available histopathologic or follow-up (over 2 years) data. We collected (patient’s age, symptoms, mammographic...

Acceleration sensors are usually used to measure the vibration of a structure. Although this is most accurate method, it cannot be remotely because these contact-type sensors. This makes measurement difficult in areas that easily approached by surveyors, such as structures located high or dangerous areas. Therefore, method can structural without installing required for Many conventional studies have been carried out on non–contact-type methods using cameras. However, they applied with...

Anaplastic thyroid cancer (ATC) is a rare tumor with lethal clinical course despite aggressive multimodal therapy. Intensity-modulated radiotherapy (IMRT) may achieve good therapeutic outcome in ATC patients, and the role of IMRT should be assessed. We retrospectively reviewed outcomes for treated three-dimensional conformal (3D-CRT) or to determine optimal treatment option explore (RT). Materials and.Between December 2000 2015, 41 patients pathologically proven received RT sufficient dose...

This paper proposes an anomaly detection scheme based on LSTM autoencoder for energy management, which is to prevent states before they actually occur. When the prognosis of state detected, can be prevented by taking appropriate measures. However, it difficult determine normal and anomalous data, since consumption varies greatly depending weather, time, day week season. Thus, this using detect a data pattern that deviates from as state. Experimental results show discriminate observed...

In order to reduce the memory access time for a Single-Instruction Multiple-Data stream (SIMD) computer with pq processing elements attached host computer, multiaccess system is proposed. The proposed supports simultaneous data within 4-directional block (p /spl times/ q), row (1 pq), column (pq 1), forward-diagonal, and backward-diagonal subarray constant interval in an arbitrary position M N array of elements, where number modules, m, prime greater than pq. For simple fast address...

It is easy to segment the liver with existing methods using both basic place information (the exists on left of abdominal CT image) and distribution regular gray values. However, can not be used for segmenting an abnormal liver. Because values lesions do show original liver, lesion parts are regarded as in methods. In this study, we use adaptive threshold each slice angle line method segmentation images.
