摘要:
A system for performing a medical procedure on a patient is provided. The system can include an imaging head defining a field of view relative to the patient. The imaging head can include at least one transmitter that emits at least one signal in the field of view, and at least one receiver that receives at least one reflected signal from the field of view. The at least one reflected signal received can be based on at least one electrical property of at least one material in the field of view. The system can further include a workstation, which can determine, based on the at least one reflected signal received by the at least one receiver, a location of at least one boundary of the material within the field of view. The system can include a display that displays an image of the location of the at least one boundary.

Es wird eine Vorrichtung zum Auslesen von wenigstens einer insbesondere flexiblen Speicherfolie beschrieben. Die Auslesevorrichtung umfasst eine Leseeinrichtung zum Auslesen von auf der Speicherfolie gespeicherten Informationen einer Transporteinrichtung mit wenigstens einem Antriebsmittel zum Transportieren der Speicherfolie relativ zur Leseeinrichtung entlang eines Führungsmittels auf einem Transportweg. Der Transportweg ist in seiner Form an die Form eines Lesebereichs der Leseeinrichtung angepaßt. Es ist wenigstens ein im Wesentlichen fester Träger (1) für die Speicherfolie vorgesehen. Die Form und die Abmessungen des Trägers (1) sind an die Form des Transportweges angepaßt. Beim Transport der Speicherfolie mit dem Träger (1) kommt die Speicherfolie nicht mit dem Antriebsmittel in Kontakt. Außerdem wird der Träger (1) für die Speicherfolie beschrieben.

A scanning apparatus including a cylindrical member (12) and an optical system (14) . The cylindrical member rotates about a rotational axis (16) and has an outer surface (18) to support a storage phosphor sample (20) thereon. The optical system moves in translation in a direction (22) parallel to the rotational axis to scan the sample. The optical system comprises an opening (40) , an excitation beam (42) , an integrating member (50) , and a single detector (54) . The excitation beam (42) is directed through the opening (40) to impinge on a sample (20) and cause light to be emitted from the sample. The integrating member (50) reflects the emitted light using an interior three-dimensional polynomial surface providing diffuse reflection. The single detector (54) is disposed adjacent the integrating member (50) for collecting the reflected emitted light.

A medical image processing system (100) having: an input section (10) for inputting image information of a patient; an output section (90) for visualizing the image information of a patient inputted from the input section; and an image-attached information recording section (11); wherein, the image-attached information recording section records, as information attached to image information, at least one of information of the input section which has been used for inputting the image information, and information of the cassette (150) which has been loaded in the input section (10) and used for inputting the image information or on the stimulable phosphor sheet loaded in the cassette.
摘要:
In an image identification method a digital signal representation of a marker preferably having an outlook which varies with orientation is coupled to a radiation image so that the quadrant in which the marker is located is invariable.
摘要:
Data identifying a radiographic image are entered manually into an identification station and transferred by radiofrequency transmission from said identification station to a radiofrequency tag provided on a cassette conveying a photostimulable phosphor screen wherein a radiographic image has been stored.
摘要:
An x-ray photographic apparatus comprises an x-ray generator (13) for transmitting x-ray radiation through an object or patient under examination. The x-ray image obtained thereby is photographed by a television camera (14,15). The output from the camera is then converted into digital form by an analog-to-digital converter (16). The resulting digital data are successively stored in a memory (17) having a storage capacity just large enough to store data relating to one image frame. The data stored in the memory are read out by first readout means (10,18) and are then converted into analog form by a first digital-to-analog converter (27). A television monitor (28), which operates in synchronism with the reading out of data from the memory, is supplied with the output from the first D/A converter so that the monitor displays the image. A register (30) stores an amount of the output read from the memory which corresponds to one image line. Data are repeatedly read from this register by second readout means (9,21-1 to 21-n,24) and are converted into analog form by a second digital-to-analog converter (32). Data relating to one image line are then fed to a cathode ray tube (35), which applies a scanning light signal to photosensitive paper (37) to print the image line thereon. As each line of the image is printed on the paper, the paper is shifted in stepwise fashion by a stepping motor (42) so that a complete printed image is formed, corresponding to a selected one of the images produced by the transmission of x-ray radiation through the object or patient.
