Digital Imaging and Communications in Medicine. What is DICOM? Why is it important? The standard language of PACS. Includes scheduling, work list, exam data, technologists notes, radiologists report, inventory, billing What are a few examples of a HIS? epic, cerner, meditech What are a few examples of a RIS? McKesson, GE Imagecast What are a few examples of PACS? Centricity, VistA What is the function of a PACS system? Image management. What image quality factor lets us see very tiny things or slight variation in borders? Spatial resolution What characteristics do we aim for in an IR? durabilityĮxposure latitude What does HIS stand for? hospital information system- database containing all patient record information except for radiology What does RIS stand for? Radiology Information System. in an IR with very high exposure latitude a tech's technique could be bad and it would compensate for it. What do we mean when we talk about an IR's exposure latitude? It's the range of MAS or kVp that an IR can compensate for, I.E. More shades of gray, allows for greater contrast. When we talk about an IR's dynamic range, what do we mean? The larger an IR's dynamic range is the greater it can discriminate between varying degrees of exit beam intensity. When we say an IR is high or low speed, what do we mean? A high speed IR is desirable because it means it is sensitive and responsive to low doses of exit beam radiation. transcribed report Can a CR image plate receive light from another image source? Yes. What is the typical CR workflow? -Ordered Does PSP's ability to absorb energy fatigue over time? Yes. Loses about 25% of energy within 8 hours.

What does PSP stand for? photo stimulable phosphor Can PSP hold on to energy indefinitely? No. Image plate must be erased via intense white light. digital signal is amplified and read by ADC

Photo detector in reader reads released photon and converts it to digital signal. As the laser strikes the phosphor it strikes the excited electron. Identify the components and process in which an Xray is captured and read via CR -penetrating X ray is captured in PSP when impacted electron becomes excited. Technique creep should replace dose creep in trying to minimize dose as much as possible.

The exposure latitude and dynamic arrange allows you to be lazy. Dose creep happens when techs are not reducing exposures as frequently as with film IR.

Shot histogram and stored histogram are compared and allow the software to decide what values to include or not include. What is histogram analysis used for? Software has stored histogram models, each having a shape characteristic of the anatomic region and projection. Y=incidence of pixels at each exposure level. What do the X & Y axis on a histogram indicate? X=amount of exposure Image and assess the raw data prior to image display. Histogram analysis is an image-processing technique commonly used to identify the edges of an It converts high energy xrays directly to electrons, which are captured via a TFT matrix. Which indirect DR systems use an A/D Converter? Both CCD/CMOS + TFT Which IR systems use a scintillator? DR Indirect CCD/CMOS + TFT Which IR systems don't use a scintillator? DR Direct TFT, CR (uses a phosphor) What is a PSP typically composed of? barium fluorohalide doped with europium (BaFX:Eu) How does a direct DR TFT system differ from an indirect one? A direct system has a single capture/conversion layer made of A-Se. How, primarily, do a TFT and CCD/CMOS system differ? A TFT reads electrons, a CCD/CMOs reads photons. Photoconductive material, amorphous silicon array(ASi), converts low energy light to electrons. Converts high energy x ray photons to low energy light. Scintillator (CsI & Gadolinium Oxysulfide) in a needle formation. What are the steps of a DR, Indirect, TFT system? 1.
