  • Recently the development of medical modality like as MRI, 3D US, DR etc is very active. Therefore it is more required not only the enhancement of quality in medical service but the improvement of medical system based on quantization, minimization, and optimization of high speed. Especially, as the changing into the digital modality system, it gets to start using ASIC(Application Specific Integrated Circuit) to realize one board system. It requires the implementation of hardware debugging and effective speedy algorithm with more speed and accuracy in order to support and replace existing device. If objected image could be linked to high speed process board with special interface and pre-processed using FPGA, it can be used in real time image processing and protocol of HIS(Hospital Information System). This study can support the basic circuit design of medical image board which is able to realize image processing basically using digitalized medical image, and to interface between existing device and image board containing image processing algorithm.

  • In this paper, we analysis 3 types of magnetic resonance image for determining whether brain infarction period is hyperacute or not. If its peirod is hyperacute, we can predict brain infarction transition direction. We use EPI(Echo Planar Image) for prediction of brain infarction transition direction. EPI is a good image for detecting brain infarction because EPI can detect the moving of water in brain which play an important role in deciding method of medical treatment. We utilize characteristics of 3 type of MRI and their relation in brain infarction patient for determining brain infarction period. By this method, we obtain each period characteristics and predict brain infarction transition direction more accurately comparing past method.

  • The classification of herniated intervertebral cervical disc types are clinically important, as treatment methods would be slightly different according to the specific type of the herniated disc. 423 patients who suffered from herniated intervertebral cervical discs were tested with Magnetic Resonance Imaging (MRI), to distinguish the type of the herniated discs. The followings are the results ; 1) The age of the patients tested ranged from 16 to 75 years old and the mean age of the patients was 41.4 years of age. 2) There were twice as many male patients, with a ratio of 288 : 135 men to women. 3) 101 patients suffered from single herniated discs, while 322 patients suffered from multi-herniated discs. 4) Of single herniated disc injuries, 52 patients had protruded discs (52%), while 25 patients had extruded discs (25%). 21 Patients (21%) had herniated intervertebral discs between $C_4{\sim}C_5$, and 51 patients (50%), and had the same injury between $C_5$ and $C_6$. 5) Of multi-herniated disc injuries, 140 patients had protruded discs(44%). while 45 patients had extruded discs (14%). 54 patients had both protruded and extruded discs(17%). 36 patients(11%), herniated discs $C_3{\sim}C_6$ ; 69 patients (21%), herniated discs $C_3{\sim}C_7$ ; 47 patients(15%) herniated discs $C_4{\sim}C_6$ and 67 patients(20%) herniated discs $C_5{\sim}C_7$.

  • We experienced a case of upper esophageal leiomyoma successfully excised by thoracoscopic surgery. A 29-year-old male was presented with retrosternal discomfort and mild dysphagia and an esophagogram revealed smooth fElling defect In the upper third of the intrathor cic esophagus, and esophagoscopy showed a submucosal tumor without mucosal infiltration. Chest CT and MRI were performed to confirm size, character and location of the esophageal mass, the absence of infiltration of surrounding structures, and to define mediastinal Iymphadenopathy. The tumor was excised by thoracoscopic surgery and it was diagnosed as leiomyoma (4$\times$2xlcm in size). The postoperative course was uneventful.

  • The artifacts in sonography is not always harmful. Sometimes it is beneficial for the evaluation of the water contents of the soft tissue and estimating the degree of inflammation and character of the regenerated tissue indirectly using artifacts such as acoustic shadowing and the enhanced transmission. It can also be useful to evaluate the possibility of aspiration of the calcifies masses by knowing of the contents of the water among them. Unlike the MRI it is useful to get real time informations with low cost in diagnosis and treatment of the soft tissue disease usinf artifacts in sonography.

  • According as society looks graying trend gradually, more shaped system that can achieve measuring health-state of old people more harmoniously construction required in field of old people's welfare and medical treatment. Health-state is measured by two methods of contact and non-contact. The first, for example measurement of blood pressure or electrocardiogram, requires that measuring equipments are attached on human body but the second, for example X-Ray or MRI, is not. But both of methods are have some of defect, for example attaching equipments, needing of the special equipments or the necessary time, etc. Therefore desirable method of monitoring system must have minimum interrupt about daily life. This study suggest the system that can monitor the user, especially old people's outward aging and health-state by use the PAN TILTER and CCD camera.

  • A 66-year-old man visited author's institute complaining of the swelling on the submandibular gland area. Clinically, the exophytic mass penetrated the skin of the submandibular area. On MRI, the lesion occupied the left submandibular space and extended downward, protruding exterior to the subcutaneous fat layer, but the center of the lesion was located on the side of the skin and the growth exterior to the skin was prominent. Demarcation of the lesion and the submandibular gland was unclear. Histopathologically the epithelial nests and keratin production were seen, then the biopsy result was squamous cell carcinoma. The stroma of lesion showed a myxoid characteristic and some ducts showed metaplasia of the ductal cells, which suggested the gland-origin carcinoma. However, lots of keratin production and carcinomatous change of cells continuous to the normal epithelium of the skin, the skin-origin carcinoma invading into the submandibular gland area could not be excluded.

  • Anomalies of the medial meniscus are rare and difficult to diagnose clinically. Among these anomalies, anomalous insertion of the medial meniscus into the anterior cruciate ligament is rare. Most of the reported cases had no relation to clinical symptoms and were found incidentally during arthroscopy. We report a rare case of anomalous insertion of the medial meniscus into the anterior cruciate ligament with a brief review of the literature.

  • Currently, x-ray is mostly used for the diagnosis of dental cavity and osteoporosis. The osteoporosis is broadly defined as a decrease in the amount of bone mass per unit volume of the bone. Clinically the manifestation of low bone mass presents a clinical problem to the general population as an increase in fracture risk and especially in aging population[1]. Although the amount of the irradiated x-ray to the human body for the clinical diagnosis is relatively small, the exposition of the x-ray to the human body should be minimized as much as possible, since the x-ray is an ionizing radiation. To investigate other possible systems replacing X-ray, ultrasonic imaging and MRI(Magneto-Resonance-Imaging) systems were studied. Unfortunately, an effective and safe diagnosis tool for detecting the dental cavity and the osteoporosis is currently lacking. (omitted)
