What is the average radiology technologist salary by state?
We’ve identified ten states where the typical salary for a Radiology Technician job is above the national average. Topping the list is Massachusetts, with Hawaii and Connecticut close behind in second and third. Connecticut beats the national average by 6.3%, and Massachusetts furthers that trend with another $4,078 (8.0%) above the $51,107.
What is radiology, and is it covered?
What is radiology, and is it covered? By definition, radiology is the science dealing with X-rays and other high-energy radiation, especially the use of such radiation for the diagnosis and treatment of disease. It is used to detect an assortment of conditions, from abnormal internal growths to pregnancy, by use of an ultrasound.
What is the difference between CT and CR?
Both DR and CR modalities produce a 2D image of the object. In contrast, CT systems produce a 3D image that is created by taking multiple image 'slices' (usually many thousands) at different angles around a single axis of object rotation.
What does CR and DR mean in radiology?
Both computed radiography (CR) and digital radiography (DR) require the use of digital technologies which rely on computer networks and high-bandwidth web facilities. DR uses flat panel detectors based on direct or indirect conversion of X-rays to charge, which is then processed to produce a digital image.
What does CR modality mean?
Defined Terms for the Modality (0008,0060) tag are: CR. Computed Radiography. CT. Computed Tomography.
Which is better CR or DR?
DR offers superior throughput compared to CR because it embeds the imaging processing cycle in the acquisition task: images can appear as quickly as five seconds. CR involves more steps because cassette processing takes longer.
How does a CR system work?
Computed radiography (CR) uses a cassette similar to a film cassette. Instead of film, the cassette holds an imaging plate (IP), which is similar to an intensifying screen. Instead of emitting light when x-rays interact with it, the IP stores the x-ray energy in proportion to the intensity it receives.
What are CR imaging plates made of?
The imaging plate (IP) is a new and flexible X-ray sensor for the CR system which uses the conventional medical X-ray imaging system and can be employed as a substitute for the screen/film system. The IP is made by densely applying particles of inorganic crystals called photostimulable phosphor onto a polyester film.
What is CR plate?
The CR plate is inserted into a reader that contains a laser that scans across the imaging plate, releasing the stored energy causing the emission of light.
What are the types of computed radiography system?
computed radiography.direct digital radiography. flat panel detector (FPD) charge-coupled device (CCD)
What is DR in radiology?
Digital radiography (DR) is the direct conversion of transmitted X-ray photons into a digital image using an array of solid-state detectors such as amorphous selenium or silicon, with computer processing and display of the image.
Whats does DR mean?
DoctorDr. is a written abbreviation for Doctor. ...
What is credit and debit?
What are debits and credits? In a nutshell: debits (dr) record all of the money flowing into an account, while credits (cr) record all of the money flowing out of an account. What does that mean? Most businesses these days use the double-entry method for their accounting.
Does Dr mean I owe money?
Your bank must normally approve an overdraft in advance. Charges also apply if you use your overdraft facility or try to make a transaction when you do not have enough funds. Overdrawn balance is marked with the letters dr (meaning debit).

CR follows a simple 3-step process
When the IP is exposed to X-ray or gamma radiation, the phosphor layer in the plate stores the image. As the IP is read by the scanner, a focused laser releases the stored image in the form of visible light photons. These photons are collected and amplified by the scanner, converted to a digital signal and then transferred to a computer for processing and display..
What are the advantages?
Film radiography offers little opportunity to vary the technique, other than picking a different film type. CR also offers different imaging plates, but also there are many scanner control parameters that can be adjusted to the required inspection task, optimizing image quality and maximizing productivity.
High definition Computed Radiography
When used with correspondingly high resolution phosphor storage plates, the ScanX Discover HR meets all the stringent requirements of the EN14784, EN17636 and ASTM E2446 standards. This combination of high resolution imaging plates and the ScanX Discover HR scanner achieves a Basic Spatial Resolution (BSR) of 30 µm across all system classes.
What is Computed Radiography (CR) ?
Computed Radiography — or CR for short — is the use of a Phosphor Imaging Plate to create a digital image. CR uses a cassette based system like analog film and is more commonly considered to be a bridge between classical radiography and the increasingly popular fully digital methods.
What are the risks of CR?
What is Computed Radiography (CR) ? 1 Long time to view image 2 Risk of overexposure 3 High Maintenance
What is DR in radiology?
Digital Radiography (DR) is the latest advancement to the radiography field, using a digital x-ray detector to automatically acquire images and transfer them to a computer for viewing. This system is additionally capable of fixed or mobile use.
Do CR cassettes speed up workflow?
CR systems also do not speed up your workflow in the same way as a DR panel and can require more maintenance. CR cassettes may additionally run the risk of getting damaged if improperly stored or handled, but are much cheaper to replace if dropped than a wireless DR panel. Pros. Low initial investment.
Is CR the same as conventional film?
Often considered the most initially cost friendly choice, CR is used almost exactly like conventional film, and so requires few changes to your office or workflow, and requires a smaller initial investment compared to DR devices of similar quality.
Is digital radiography more expensive?
While it is the more expensive option, the Digital Radiography system comes to the table with much higher efficiency and quality that more than justifies the price for many users. Given its high volume capabilities it is often the choice for larger or busier clinics.
