Abstract

The invention relates to a medical system comprising a detection device for detecting an object in at least two dimensions by x-rays. The detection device is constructed to detect the object and to produce data comprising a 2D data record or a sequence of 2D data records over time representing the object in a projection through the object in two dimensions and to output the data. The medical system comprises at least one storage device with a data input actively connected to the detection device and which is constructed to receive the data at the input side and to write on a storage medium, in particular a portable storage medium, in such a way that the storage medium represents the data so it can be read out again. The medical system is constructed to digitally transmit the data from the detection device through to the storage device.

Dependent claims

A medical system, comprising:

a detection device that detects an object in at least two dimensions and outputs a data record of the object;
a storage device actively connected to the detection device that receives the data record and writes the data records on a storage medium of the storage device, the data record being digitally transmitted from the detection device to the storage device;
and
an imaging processing device connected to the storage device that changes the data record according to a predetermined allocation rule and the changed data record is saved on the storage device,
wherein the imaging processing device comprises:
a high-pass filter that filters location-dependent spatial frequencies of the data record for intensifying an image contrast of the data record, and
a low-pass filter that filters the location-dependent spatial frequencies of the data record for attenuating the image contrast of the data record,
an image definition filter that filters the location-dependent spatial frequencies of the data record for reducing a location-dependent image resolution of the data record so that mutually adjacent pixels of the data record represents a same brightness and/or color value respectively,
wherein the detection device is configured to digitally transmit the data record to the storage device in a combination of binary, octal, or hexadecimal comprising binary and octal, binary and hexadecimal, or octal and hexadecimal, and
wherein the storage medium comprises at least two storage layers arranged parallel to each other.

7 more elements

A method for storing a data record of an object, comprising:

generating the data record of the object by detecting the object;
digitally transmitting the data record to a storage device;
optically storing the data record on a storage medium of the storage device for reading out the data record again;
changing the data record according to a predetermined allocation rule;
and
storing the changed data record on the storage medium of the storage device for reading out the changed data record again,
wherein the data record is changed according to the predetermined allocation rule by:
filtering location-dependent spatial frequencies of the data record by a high-pass filter for intensifying an image contrast of the data record,
filtering the location-dependent spatial frequencies of the data record by a low-pass filter for attenuating the image contrast of the data record,
filtering the location-dependent spatial frequencies of the data record by an image definition filter for reducing a location-dependent image resolution of the data record so that mutually adjacent pixels of the data record represents a same brightness and/or color value respectively,
wherein the data record is digitally transmit to the storage device in a combination of binary, octal, or hexadecimal comprising binary and octal, binary and hexadecimal, or octal and hexadecimal, and
wherein the storage medium comprises at least two storage layers arranged parallel to each other.
