|---|---|---|---|---|---|
| show | cross over
🗑
|
||||
| -substratum coat, used to glue emulsion to base -prevents bubbles during handling and processing | show 🗑
|
||||
| -made of gelatin -actually captures latent image -colloidal substance -chemically non reactive -distributes crystals evenly(prevents clumping=mottle) -clear, flexible -contains silver halide crystals | show 🗑
|
||||
| when would single emulsion film be used | show 🗑
|
||||
| show | identifies the batch of film (batch #)
🗑
|
||||
| what is the chronological history of the film screen base layer | show 🗑
|
||||
| provides mechanical support -inflamable -non-tear -flexible -stable/rigid -uniform lunicy -blue tint to reduce eye strain -archival quality | show 🗑
|
||||
| show | silver halide -95-98% are siver bromi -2-5% are silver iodide or silver chloride *the halides are bromide and iodide -this is what captures the latent image
🗑
|
||||
| show | silver halide crystals used in film today
🗑
|
||||
| show | -cubic -octhedral -polyhedral -irregular
🗑
|
||||
| show | -has lattice formation -chemically combined with ionic bonds(+ charged silver ions and - charged bromide and iodide ions) -each crystal has a point of imperfection called the sensitivity speck,this allows for latent image acquisition
🗑
|
||||
| show | -gold-silver sulfide

|
||||
| what kind of film would be used for chest and abdominal imaging | show 🗑
|
||||
| show | high resolution(requires more mas)
🗑
|
||||
| show | to significantly reduce pt dose
🗑
|
||||

🗑
|
||||

|
||||
| show | spot film
🗑
|
||||
| show | -inventory(first in first out) -sensitive to heat and humidity, radiation and light -store on end -static artifacts if too dry -store at <68 degrees 30-60% humidity -store 18 months unopened -store for 45-60 days once open
🗑
|
||||
| show | contains: -date -pt name -MR # -intitution name -exposed by xray or light -do not write on
🗑
|
||||
| what are the 4 possible states of film | show 🗑
|
||||
| show | -tube side-radiolucent -back side-radiopaque -blocker-pt info -purpose-light tight and good film/screen contact
🗑
|
||||
| show | at least 4ft from loading bench
🗑
|
||||
| what are the four main steps of the latent image formation Gurney-Mott hypothesis in film screen | show 🗑
|
||||
| what are the different types of static artifact | show 🗑
|
||||
| show | -light -heat -radiation -pressure
🗑
|
||||
| what is the main difference between direct exposure and screen film | show 🗑
|
||||
| show | 1.make a light exposure on a film 2.take in a dark room with no lights on 3.cover half off film with lead 4.turn on safe light for 30 seconds 5.turn light of and process film 6.you can then see if there is fog or not
