Bei herkömmlicher Aufnahmedosis muß in digitalen Radiographien eine geringere Erkennbarkeit venöser Katheter in Kauf genommen werden

Detection of low contrast catheters was found to be significantly decreased in storage phosphor radiographs obtained with standard exposure dose.

Durchleuchtungsdosis = fluoroscopic dose
https://books.google.de/books?id=IkX0BQAAQBAJ&pg=PA88&lpg=PA...

As I understand it, Aufnahmedosis (radiation dose) is a general term, a dose of radiation delivered during ANY radiographic examination (X-ray, CT, mammography, fluoroscopy).

Durchleuchtung (fluoroscopy), and its radiation dose, is a special type of radiographic examination where the radiation dose tends to be higher.

So, your terms are: radiation dose and fluoroscopy radiation dose. They refer to the same thing, i.e. radiation dose, but one is general and the other one is associated with a specific type of exam.

It's somewhat like saying: juice and orange juice.

HTH

Absorbed dose is the amount of energy deposited by radiation in a mass. The mass can be anything: water, rock, air, people, etc. Absorbed dose is expressed in milligrays (mGy).

Please also note the equivalent dose and effective dose.

Absorbed dose

The absorbed dose is the amount of radiation energy absorbed by tissue per mass of tissue. Skin typically receives the highest absorbed dose.

Kerma Area Product
The kerma area product (KAP) is a measure of dose integrated across the entire exposed field. KAP is sometimes called dose area product (DAP). It is usually expressed in mGycm2.

Durchleuchtung:

• Dosisflächenprodukt (DFP) – Gy×cm²
Das Dosisflächenprodukt entspricht der gesamten, bei einer Untersuchung das
Röhren-Austrittsfenster passierenden "Strahlenmenge". Das Dosisflächenprodukt wird mittels einer Ionisationskammer am Strahlenaustrittsfenster ermittelt. Es entspricht dem Produkt aus Dosis und Nutzstrahlenfläche.

Radiographie:

• Oberflächendosis
(ESD Entrance Surface Dose) – mGy
Die Oberflächendosis ist die Energiedosis (inkl. Rückstreuung) in einem bestimmten Abstand von der Strahlenquelle auf der Oberfläche des bestrahlten Körpers. Die Werte können mittels an der Hautoberfläche angeordneten Ionisationskammer gemessen werden. Dieses Verfahren wird in der Personendosimetrie mittels dem Thermolumineszenzdosimeter (TLD) angewendet.

• Organdosis – mSv
Die Organdosis ist die absorbierte Energiedosis in einem bestimmten Organ,
welche durch ionisierende Strahlung aufgenommen wurde. Sie ist relevant für die Auswirkung auf das betroffene Gebiet, das betrifft insbesondere die
strahlensensiblen Organe.

The following link clearly shows that absorbed dose is used within cardiac angiography (angiogram):

Radiation Dose to Patients From Cardiac Diagnostic Imaging

While often easy to measure, exposure and air kerma specifically measure ionization in air, not tissue, and thus do not directly quantify radiation’s effect on humans. Absorbed dose is the mean energy imparted to the matter in a volume by ionizing radiation, divided by the mass of the matter in the volume. The SI unit of absorbed dose, introduced at the 15th CGPM in 1975, is the gray (Gy), which is a special name for joule per kilogram.
