Abstract: Through analysis of a large number of DICOM images and Analysis of DICOM standard documents, we understand the structure and composition of the image. At the same time, we analyze the BMP image to obtain the structure of the BMP image, this paper proposes a method for converting DICOM images and BMP images.Keywords DICOM; BMP; data element; PixelGraph classification: tp317.4; tn911.73 Document Identification Code: article A No.: 1003-8868 (2004) 01-0013-03

Comparison of Dr dual-energy subtraction and DR chest X-ray and CT absorption dose in the chest; Research Institute of medical imaging, Nanjing General Hospital of Nanjing Military Region (210002) Wang Jun digital X-ray photography (DR) chest double-energy subtraction plays a role in the diagnosis of pneumothorax, pulmonary nodules and calcification in nodules, rib fracture, coronary artery calcification, etc. [1-5]. However, it brings medical benefit
each sampling point are calculated by interpolation, then, the accumulated color value and opacity value are calculated from the beginning to the back or from the back to the front until the light is completely absorbed or passed through the object. This method can well reflect the changes in the material boundary. Using the phong model, the introduction of mirror reflection, diffuse reflection, and environmental reflection can produce a good illumination effect, in medicine, the properties, sh

We will not mention the distinction between coordinate systems. Many books have written it and it is easy to understand.
Generally, the modeling coordinate system is used for modeling, and then the modeling coordinate system is first converted to the world coordinate system.
In the OpenGL coordinate system, the positive direction of Z points to the outside of the screen (belonging to the right-hand coordinate system

Optical zoom:
Optical zoom occurs when the positions of the lens, object, and focus change. When the imaging surface is moving horizontally, for example, the visual and focal length will change, and the farther scenes will become clearer, making people feel like objects are moving forward. Therefore, changing the focal length of a lens is optical zoom.
An optical zoom multiple is the ratio of the maximum focal length to the minimum focal length that a

more images and videos than humans can see, why don't we consider re-designing the camera for the machine? This allows us to look at the camera from a non-human perspective .」
In other words, computer vision algorithms do not always require high resolution and high image fidelity as the human eyes do. They can get a lot of information from the "transparent, lens-less camera" of Menon and ganghun Kim, even if the image quality is not high, the cost and occupied area will be greatly reduced. Thei

To share with you photography enthusiasts the evaluation of Canon SX510 HS camera Usage test.
Share list:
As a high-power optical zoom lens portable digital camera, Canon SX510 HS no matter in the hardware to improve the performance is very good, and the use of the new CMOS back-image sensor makes Canon SX510 HS photosensitive performance has been significantly improved, Can be in the wrong shooting environment can also take a clear high-quality photos.
In addition,

The key to improving the image clarity is to improve the photographic ability of the camera.2, lens and CCD sensor components of the configurationIn Figure one, we can see that the image formed on the CCD sensor is smaller than the original image, and the size of the CCD image surface is different.CCD imaging size is commonly u

In Python, the installation of a Third-party module is done through the Setuptools tool. Python has two package management tools encapsulated in Setuptools: Easy_install and Pip. PIP is currently recommended for use by the official.
If you are using a Mac or Linux, install the PIP itself this step can be skipped.
If you are using Windows, refer to the installation of the Python section to ensure that the PIP and add Python.exe to Path are selected during installation.
