Purpose: Although Computerized Tomography is one of the most useful diagnosis devices and Frequency of use by all kind of patient is higher than other device, it can be hardly to find out adequate data to planning of Computerized Tomography Unit. So questions have been raised about how to organize the unit. Methods: In order to suggest architectural guideline of Computerized Tomography Unit, expert interview, field survey and analysis to the floor plan have been conducted in this article. The area calculation was based on center line. Results: This article suggests a number of the guideline and the example of the planning which contains how to design Computerized Tomography Unit. Especially, in the case of the example on the planning, main points of the guideline is reflected. Implications: The result of this survey would be useful as a reference when the architect tries to design Computerized Tomography unit.

In a 36-month period, 23 selected Patients with Acute Cerebral Infarction were studied utilizing Computerized Tomography, Barthel Index in an attempt to correlate Brain Computerized Tomography findings with 1week, 4weeks rehabilitation and evaluate the influences of the size and location of the lesion. The study suggested that the size of the lesion had impact on 4 weeks rehabilitation. There was significant different between the patients with Middle Cerebral Artery Pial Territory Infarction(I.P.B.M.C.A.) lesion and the patients with Lacunar Infarction(L.I.), Striatocapsular Infarction(S.C.I.), Internal Watershed Infarction(I.W.I.) lesion, but there was no significant difference between the patients with L.I. lesion and the patients with S.C.I. lesion and the patients with I.W.I. lesion. The size and location of the lesion should be considered together in predicting the functional outcomes of Acute Cerebral Infarction.

Stellate ganglion block is a well established method for the management of certain pain syndromes (e.g., chronic regional pain syndrome, facial pain) in the cervicothoracic region and upper extremity. The stellate ganglion resides between the C7 transverse process and the head of the first rib. Anesthetic injections for the stellate ganglion block are typically made at the level of the transverse process of either the C6 or C7 vertebrae to avoid the pleura, vessels, and nerve roots. Method of positioning the needle tip directly at the ganglion has been described, but are problematic because of the risk of injury to or injection into adjacent structures. It is necessary to know the exact anatomic position of the stellate ganglion when permanent blockade is required by means of radiofrequency thermocoagulation. Whereas fluroscopy shows only bony feature, computerized tomography also images nerves, vessels, and lung, allowing accruate needle placement. We report a case of the percutaneous radiofrequency thermocoagulation of the stellate ganglion after computerized tomography-guided localization.

A general optimal recovery problem is to approximate a value of a linear operator on a subset (class) in linear space from a value of another linear operator (called information), measured with an error in given metric. We use this formulation to investigate the classical computerized tomography problem of inversion of the noisy Radon transform.

Computerized tomography has become more widely available in numerous centers throughout the world and is now recognized in many specialities as an important diagnostic procedure. The use of computerized tomography in oral and maxillofacial surgery is discussed. It has been found to be of special value in the diagnosis and assesment of expanding and infiltrating lesions of the jaws, fracture and infections, especially in the midface, in both adults and children.

This paper provides the design of system software for the management of radiation dose that is generated by using computerized tomography(CT). Recently, the radiation leakage incident of Japanese nuclear power plant was in the news internationally and there is a growing interest not only in nuclear power plant but in medical radiation exposure. In spite of the fact that currently safety management of radiation is under control only the workers of the radiation involved, now the exposure management of patients have been required. As surgery and inspections using the radiation have increased, this medical radiation exposure is increasing too. But it is a real situation that medical institutions don't know the level of radiation exposure applied to the patient. Therefore, a system for managing the radiation exposure of a patient from the medical institution is required. This paper proposes a design of a software program that manages the radiation exposure of CT which is a typical imaging tool to use the radiation in the medical institution. By check the amount of radiation dose and set the limit of dose, we would be of help to optimize the medical exposure of the patient.

Old architectural wood materials damaged by a fire were evaluated on the basis of wood species and scanning electron microscopy (SEM) observation of wood tissues in combination with energy dispersive X-ray spectroscopy (EDXS) analysis. Results of SEM observation showed that tracheid wall thickness of burned parts was very thin compared with undamaged and sound wood, and tylosoid in the resin canals disappeared after the exposure to fire. SEM-EDXS analysis indicated that carbon and oxygen peaks occurred in the original energy band, and the carbon peak was higher than that of the oxygen in the burned part. A computerized tomography was also undertaken to investigate the carbonization layer formed by fire and possible internal defects.

The purpose of this study was to measure the thickness of masticatory mucosa in the hard palate as a donor site for mucogingival surgery by using computerized tomography(CT), Thickness measurements were performed in 84 adult patients who took CT on maxilla for implant surgery and 24 standard measurement points were defined in the hard palate according to the gingival margin and mid palatal suture. Radiographic measurements were utilized after calibration for standardization. Data were analyzed to determine the differences in mucosal thickness by gender, age, tooth positions and depth of palatal vault. The results of this study were as follows: 1. Mean thickness of palatal masticatory mucosa was $3.93{\pm}0.6mm$ and females had significantly thinner mean masticatory mucosa($3.76{\pm}0.56mm$) than males($4.04{\pm}0.6mm$)(p<0.05). 2. The thickness of palatal masticatory mucosa increased by aging. 3. Depending on position, masticatory mucosa thickness increased from canine to premeolar, but decreased at the first molar, and increased again in the second molar region(p<0.0001). 4. No significant difference in mean thickness of palatal masticatory mucosa were indentified between low palatal vault group and high palatal vault group(p>0.05). The results suggest that canine and premolar area appears to be the most appropriate donor site for soft tissue grafting procedure. The measurement of the thickness of palatal masticatory mucosa by using computerized tomography can offer useful information clinically but further studies in as-sessing the validity and reliability of the method using computerized tomography is needed.

The degradation of image due to the finite size of sensing devices has been one of the problems in all digital imaging systems. The basic study on the improvement of the spatial resolution was carried out in both spatial and frequency domains by the resolution recovery techniques which have been used in optics. Here, the techniques were applied to CT (Computerized Tomography) system, and image with finer resolution was obtained by these techniques. The basic theory is described and the results of the simulation are shown.
