TL;DR: The combined application of new intravascular ultrasound technology and other imaging examination methods, such as X-rays to use three-dimensional image technology to reconstruct new intvascular ultrasound image sequences, and provide doctors with clearer morphology and properties of tube wall lesions is explored.
Abstract: Since entering the 21st century, the application of ultrasound technology has developed rapidly. Intravascular ultrasound technology has been widely used in the diagnosis and treatment of cardiovascular diseases. With the help of computer image processing technology, it can provide clinicians with more accurate diagnosis. Based on the information to improve the success rate of clinical treatment. Based on this, this article combines the development history of intravascular ultrasound technology, explores the principles of new intravascular ultrasound technology, and analyzes the application of new intravascular ultrasound technology. On this basis, the preprocessing of intravascular ultrasound image data is discussed, involving the acquisition of intravascular ultrasound image data and image analysis. On this basis, explore the combined application of new intravascular ultrasound technology and other imaging examination methods, such as X-rays to use three-dimensional image technology to reconstruct new intravascular ultrasound image sequences, and provide doctors with clearer morphology and properties of tube wall lesions. In order to make a more accurate diagnosis of the lesion, a more detailed and accurate treatment plan can be given, which has extremely high clinical application value.

TL;DR: In this article, a flat panel detector, an object stage, a flat mirror and an X-ray source are sequentially arranged from top to bottom, and the centers thereof are located on the same line.
Abstract: The invention discloses an integral fluorescence transmission imaging system used for small animals; the structure of the imaging system is as follows: a flat panel detector, an object stage, a flat mirror and an X-ray source are sequentially arranged from top to bottom, and the centers thereof are located on the same line; two LBDs, the centers of which are arranged on the same horizontal line, are respectively arranged above both sides of the X-ray source; a filter and a charge-coupled device are positioned on the side of the non-working surface of the flat mirror; the filter and the charge-coupled device share a common axis which goes through the center of the flat mirror; and the flat panel detector and the charge-coupled device are connected with a computer via a data acquisition board. The invention takes the advantage of digital X-ray transmission imaging technology in terms of structural imaging to solve the problem of inaccurate tumor locating of the current integral fluorescent optical imaging technology. The invention adopts computers to fuse the images acquired by the digital X-ray transmission imaging technology and the integral fluorescent optical imaging technology, thereby acquiring more detailed tumor information. Therefore, an effective research tool is provided for researching the invasion, growth and translocation of the tumor.

TL;DR: In this article, the authors proposed an imaging technology capable of preventing deterioration in the image quality of a photographed image even when an object with a low luminance is photographed, where a gain of an amplifier for amplifying an image signal output from an imaging device of an imaging apparatus is made variable and a drive pulse received by the imaging device is switched in response to the gain setting.
Abstract: PROBLEM TO BE SOLVED: To provide an imaging technology capable of preventing deterioration in the image quality of a photographed image even when an object with a low luminance is photographed. SOLUTION: A gain of an amplifier for amplifying an image signal output from an imaging device of an imaging apparatus is made variable and a drive pulse received by the imaging device is switched in response to the gain setting. For example, when the gain is less than 12 dB, the drive pulse in a pattern A is set, wherein the number of storage gates of the imaging device is four, and when the gain is 12 dB or over, the drive pulse in a pattern B is set, wherein the number of storage gates of the imaging device is three. Although the amount of dark noises is decreased as the number of the storage gates of the imaging device is smaller, since the number of the storage gates is decreased as above in the case of a high gain, the S/N is not deteriorated. That is, the deterioration in the image quality of the photographed image can be prevented in photographing an object with a low luminance. COPYRIGHT: (C)2006,JPO&NCIPI

TL;DR: The aim of this article is to give a review of the basic principles of CT protocol design for the chest and the kinetics of contrast media injection.
Abstract: The past decade there has been an enormous advance in imaging technology, most obvious in the field of magnetic resonance imaging (MRI) and computed tomography (CT). Today nearly every radiology department has a multislice CT (MSCT) available for routine imaging, many of which are increasingly being replaced by last generation 16- and 64-slice CT scanners. However, the use of fast CT scanners requires a better insight in acquisition and contrast media injection protocols in order to achieve the best possible result. It is the aim of this article to give a review of the basic principles of CT protocol design for the chest and the kinetics of contrast media injection.

TL;DR: A review article will comprise the methodology as well as the current state of the art and standard of knowledge of magnetic resonance imaging of the lung using hyperpolarised (3)Helium.
Abstract: Current imaging methods of the lung concentrate on morphology as well as on the depiction of the pulmonary parenchyma The need of an advanced and more subtle imaging technology compared to conventional radiography is met by computed topography as the method of choice Nevertheless, computed tomography yields very limited functional information This is to be derived from arterial blood gas analysis, spirometry and body plethysmography These methods, however, lack the scope for regional allocation of any pathology Magnetic resonance imaging of the lung has been advanced by the use of hyperpolarised (3)Helium as an inhaled gaseous contrast agent The inhalation of the gas provides functional data by distribution, diffusion and relaxation of its hyperpolarised state Because anatomical landmarks of the lung can be visualised as well, functional information can be linked with regional information Furthermore, the method provides high spatial and temporal resolution and lacks the potential side-effects of ionising radiation Four different modalities have been established: 1 Spin density imaging studies the distribution of gas, normally after a single inhalation of contrast gas in inspiratory breath hold 2 Dynamic cine imaging studies the distribution of gas with respect to regional time constants of pulmonary gas inflow 3 Diffusion weighted imaging can exhibit the presence and severity of pulmonary airspace enlargement, as in pulmonary emphysema 4 Oxygen sensitive imaging displays intrapulmonary oxygen partial pressure and its distribution Currently, the method is limited by comparably high costs and limited availability As there have been recent developments which might bring this modality closer to clinical use, this review article will comprise the methodology as well as the current state of the art and standard of knowledge of magnetic resonance imaging of the lung using hyperpolarised (3)Helium
